Based on patch from David Gwynne 19285303Sgshapiro of the University of Queensland. 20285303Sgshapiro CONFIG: Allow connections from IPv6:0:0:0:0:0:0:0:1 to relay again. 21285303Sgshapiro Patch from Lars-Johan Liman of Netnod Internet Exchange. 22285303Sgshapiro CONFIG: New option UseCompressedIPv6Addresses to select between 23285303Sgshapiro compressed and uncompressed IPv6 addresses. The default 24285303Sgshapiro value depends on the compile-time option IPV6_FULL: 25285303Sgshapiro For 1 the default is False, for 0 it is True, thus 26285303Sgshapiro preserving the current behaviour. Based on patch from 27285303Sgshapiro John Beck of Oracle. 28285303Sgshapiro CONFIG: Account for IPv6 localhost addresses in 29285303Sgshapiro FEATURE(`block_bad_helo'). Suggested by Andrey Chernov 30285303Sgshapiro from FreeBSD and Robert Scheck from the Fedora Project. 31285303Sgshapiro CONFIG: Account for IPv6 localhost addresses in check_mail ruleset. 32285303Sgshapiro LIBMILTER: Deal with more invalid protocol data to avoid potential 33285303Sgshapiro crashes. Problem noted by Dimitri Kirchner. 34285303Sgshapiro LIBMILTER: Allow a milter to specify an empty macro list ("", not 35285303Sgshapiro NULL) in smfi_setsymlist() so no macro is sent for the 36285303Sgshapiro selected stage. 37285303Sgshapiro MAKEMAP: A change to check TrustedUser in fewer cases which was 38285303Sgshapiro made in 2013 caused a potential regression when makemap 39285303Sgshapiro was run as root (which should not be done anyway). 40285303Sgshapiro Note: sendmail often contains options "For Future Releases" 41285303Sgshapiro (prefix _FFR_) which might be enabled in a subsequent 42285303Sgshapiro version or might simply be removed as they turned out not 43285303Sgshapiro to be really useful. These features are usually not 44285303Sgshapiro documented but if they are, then the required (FFR) 45285303Sgshapiro options are listed in 46285303Sgshapiro - doc/op/op.* for rulesets and macros, 47285303Sgshapiro - cf/README for mc/cf options. 48285303Sgshapiro 49285303Sgshapiro8.15.1/8.15.1 2014/12/06 50285303Sgshapiro SECURITY: Properly set the close-on-exec flag for file descriptors 51285303Sgshapiro (except stdin, stdout, and stderr) before executing mailers. 52285303Sgshapiro If header rewriting fails due to a temporary map lookup failure, 53285303Sgshapiro queue the mail for later retry instead of sending it 54285303Sgshapiro without rewriting the header. Note: this is done 55285303Sgshapiro while the mail is being sent and hence the transaction 56285303Sgshapiro is aborted, which only works for SMTP/LMTP mailers 57285303Sgshapiro hence the handling of temporary map failures is 58285303Sgshapiro suppressed for other mailers. SMTP/LMTP servers may 59285303Sgshapiro complain about aborted transactions when this problem 60285303Sgshapiro occurs. 61285303Sgshapiro See also "DNS Lookups" in sendmail/TUNING. 62285303Sgshapiro Incompatible Change: Use uncompressed IPv6 addresses by default, 63285303Sgshapiro i.e., they will not contain "::". For example, 64285303Sgshapiro instead of ::1 it will be 0:0:0:0:0:0:0:1. This 65285303Sgshapiro permits a zero subnet to have a more specific match, 66285303Sgshapiro such as different map entries for IPv6:0:0 vs IPv6:0. 67285303Sgshapiro This change requires that configuration data 68285303Sgshapiro (including maps, files, classes, custom ruleset, 69285303Sgshapiro etc) must use the same format, so make certain such 70285303Sgshapiro configuration data is updated before using 8.15. 71285303Sgshapiro As a very simple check search for patterns like 72285303Sgshapiro 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. If necessary, 73285303Sgshapiro the prior format can be retained by compiling with: 74285303Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-DIPV6_FULL=0') 75285303Sgshapiro in your devtools/Site/site.config.m4 file. 76285303Sgshapiro If debugging is turned on (-d0.14) also print the OpenSSL 77285303Sgshapiro versions, both build time and run time 78285303Sgshapiro (provided STARTTLS is compiled in). 79285303Sgshapiro If a connection to the MTA is dropped by the client before its 80285303Sgshapiro hostname can be validated, treat it as "may be forged", 81285303Sgshapiro so that the unvalidated hostname is not passed to a 82285303Sgshapiro milter in xxfi_connect(). 83285303Sgshapiro Add a timeout for communication with socket map servers 84285303Sgshapiro which can be specified using the -d option. 85285303Sgshapiro Add a compile time option HESIOD_ALLOW_NUMERIC_LOGIN to allow 86285303Sgshapiro numeric logins even if HESIOD is enabled. 87285303Sgshapiro The new option CertFingerprintAlgorithm specifies the finger- 88285303Sgshapiro print algorithm (digest) to use for the presented cert. 89285303Sgshapiro If the option is not set, md5 is used and the macro 90285303Sgshapiro {cert_md5} contains the cert fingerprint. 91285303Sgshapiro However, if the option is set, the specified algorithm 92285303Sgshapiro (e.g., sha1) is used and the macro {cert_fp} contains 93285303Sgshapiro the cert fingerprint. 94285303Sgshapiro That is, as long as the option is not set, the behaviour 95285303Sgshapiro does not change, but otherwise, {cert_md5} is superseded 96285303Sgshapiro by {cert_fp} even if you set CertFingerprintAlgorithm 97285303Sgshapiro to md5. 98285303Sgshapiro The options ServerSSLOptions and ClientSSLOptions can be used 99285303Sgshapiro to set SSL options for the server and client side 100285303Sgshapiro respectively. See SSL_CTX_set_options(3) for a list. 101285303Sgshapiro Note: this change turns on SSL_OP_NO_SSLv2 and 102285303Sgshapiro SSL_OP_NO_TICKET for the client. See doc/op/op.me 103285303Sgshapiro for details. 104285303Sgshapiro The option CipherList sets the list of ciphers for STARTTLS. 105285303Sgshapiro See ciphers(1) for possible values. 106285303Sgshapiro Do not log "STARTTLS: internal error: tls_verify_cb: ssl == NULL" 107285303Sgshapiro if a CRLFfile is in use (and LogLevel is 14 or higher.) 108285303Sgshapiro Store a more specific TLS protocol version in ${tls_version} 109285303Sgshapiro instead of a generic one, e.g., TLSv1 instead of 110285303Sgshapiro TLSv1/SSLv3. 111285303Sgshapiro Properly set {client_port} value on little endian machines. 112285303Sgshapiro Patch from Kelsey Cummings of Sonic.net. 113285303Sgshapiro Per RFC 3848, indicate in the Received: header whether SSL or 114285303Sgshapiro SMTP AUTH was negotiated by setting the protocol clause 115285303Sgshapiro to ESMTPS, ESMTPA, or ESMTPSA instead of ESMTP. 116285303Sgshapiro If the 'C' flag is listed as TLSSrvOptions the requirement for the 117285303Sgshapiro TLS server to have a cert is removed. This only works 118285303Sgshapiro under very specific circumstances and should only be used 119285303Sgshapiro if the consequences are understood, e.g., clients 120285303Sgshapiro may not work with a server using this. 121285303Sgshapiro The options ClientCertFile, ClientKeyFile, ServerCertFile, and 122285303Sgshapiro ServerKeyFile can take a second file name, which must be 123285303Sgshapiro separated from the first with a comma (note: do not use 124285303Sgshapiro any spaces) to set up a second cert/key pair. This can 125285303Sgshapiro be used to have certs of different types, e.g., RSA 126285303Sgshapiro and DSA. 127285303Sgshapiro A new map type "arpa" is available to reverse an IP (IPv4 or IPv6) 128285303Sgshapiro address. It returns the string for the PTR lookup, but 129285303Sgshapiro without trailing {ip6,in-addr}.arpa. 130285303Sgshapiro New operation mode 'C' just checks the configuration file, e.g., 131285303Sgshapiro sendmail -C new.cf -bC 132285303Sgshapiro will perform a basic syntax/consistency check of new.cf. 133285303Sgshapiro The mailer flag 'I' is deprecated and will be removed in a 134285303Sgshapiro future version. 135285303Sgshapiro Allow local (not just TCP) socket connections to the server, e.g., 136285303Sgshapiro O DaemonPortOptions=Family=local, Addr=/var/mta/server.sock 137285303Sgshapiro can be used. 138285303Sgshapiro If the new option MaxQueueAge is set to a value greater than zero, 139285303Sgshapiro entries in the queue will be retried during a queue run 140285303Sgshapiro only if the individual retry time has been reached which 141285303Sgshapiro is doubled for each attempt. The maximum retry time is 142285303Sgshapiro limited by the specified value. 143285303Sgshapiro New DontBlameSendmail option GroupReadableDefaultAuthInfoFile 144285303Sgshapiro to relax requirement for DefaultAuthInfo file. 145285303Sgshapiro Reset timeout after receiving a message to appropriate value if 146285303Sgshapiro STARTTLS is in use. Based on patch by Kelsey Cummings 147285303Sgshapiro of Sonic.net. 148285303Sgshapiro Report correct error messages from the LDAP library for a range of 149285303Sgshapiro small negative return values covering those used by OpenLDAP. 150285303Sgshapiro Fix compilation with Berkeley DB 5.0 and 6.0. Patch from 151285303Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 152285303Sgshapiro CONFIG: FEATURE(`nopercenthack') takes one parameter: reject or 153285303Sgshapiro nospecial which describes whether to disallow "%" in the 154285303Sgshapiro local part of an address. 155285303Sgshapiro DEVTOOLS: Fix regression in auto-detection of libraries when only 156285303Sgshapiro shared libraries are available. Problem reported by 157285303Sgshapiro Bryan Costales. 158285303Sgshapiro LIBMILTER: Mark communication socket as close-on-exec in case 159285303Sgshapiro a user's filter starts other applications. 160285303Sgshapiro Based on patch from Paul Howarth. 161285303Sgshapiro Portability: 162285303Sgshapiro SunOS 5.12 has changed the API for sigwait(2) to conform 163285303Sgshapiro with XPG7.

Without this SHA2 algorithms may not 180261363Sgshapiro work properly, causing for example failures for certs 181261363Sgshapiro that use sha256WithRSAEncryption as signature algorithm. 182261363Sgshapiro When looking up hostnames, ensure only to return those records 183261363Sgshapiro for the requested family (AF_INET or AF_INET6). 184261363Sgshapiro On system that have NEEDSGETIPNODE and NETINET6 185261363Sgshapiro this may have failed and cause delivery problems. 186261363Sgshapiro Problem noted by Kees Cook. 187261363Sgshapiro A new mailer flag '!' is available to suppress an MH hack 188261363Sgshapiro that drops an explicit From: header if it is the 189261363Sgshapiro same as what sendmail would generate. 190261363Sgshapiro Add an FFR (for future release) to use uncompressed IPv6 addresses, 191261363Sgshapiro i.e., they will not contain "::". For example, instead 192261363Sgshapiro of ::1 it will be 0:0:0:0:0:0:0:1. This means that 193261363Sgshapiro configuration data (including maps, files, classes, 194261363Sgshapiro custom ruleset, etc) have to use the same format. 195261363Sgshapiro This will be turned on in 8.15. It can be enabled in 8.14 196261363Sgshapiro by compiling with: 197261363Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_IPV6_FULL') 198261363Sgshapiro in your devtools/Site/site.config.m4 file. 199261363Sgshapiro Add an additional case for the WorkAroundBrokenAAAA check when 200261363Sgshapiro dealing with broken nameservers by ignoring SERVFAIL 201261363Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time. 202261363Sgshapiro Problem noted by Pavel Timofeev of OCS. 203261363Sgshapiro If available, pass LOGIN_SETCPUMASK and LOGIN_SETLOGINCLASS to 204261363Sgshapiro setusercontext() on deliveries as a different user. 205261363Sgshapiro Patch from Edward Tomasz Napierala from FreeBSD. 206261363Sgshapiro Avoid compiler warnings from a change in Cyrus-SASL 2.1.25. 207261363Sgshapiro Patch from Hajimu UMEMOTO from FreeBSD. 208261363Sgshapiro Add support for DHParameters 2048-bit primes. 209261363Sgshapiro CONFIG: Accept IPv6 literals when evaluating the HELO/EHLO argument 210261363Sgshapiro in FEATURE(`block_bad_helo'). Suggested by Andrey Chernov. 211261363Sgshapiro LIBSMDB: Add a missing check for malloc() in libsmdb/smndbm.c. 212261363Sgshapiro Patch from Bill Parker. 213261363Sgshapiro LIBSMDB: Fix minor memory leaks in libsmdb/ if allocations 214261363Sgshapiro fail. Patch from John Beck of Oracle. 215261363Sgshapiro Portability: 216261363Sgshapiro Add support for Darwin 12.x and 13.x (Mac OS X 10.8 and 10.9). 217261363Sgshapiro On Linux use socklen_t as the type for the 3rd argument 218261363Sgshapiro for getsockname/getpeername if the glibc version is at 219261363Sgshapiro least 2.1. 220261363Sgshapiro Added Files: 221261363Sgshapiro devtools/OS/Darwin.12.x 222261363Sgshapiro devtools/OS/Darwin.13.x 223261363Sgshapiro 224249729Sgshapiro8.14.7/8.14.7 2013/04/21 225249729Sgshapiro Drop support for IPv4-mapped IPv6 addresses to prevent the MTA 226249729Sgshapiro from using a mapped address over a legitimate IPv6 address 227249729Sgshapiro and to enforce the proper semantics over the IPv6 228249729Sgshapiro connection. Problem noted by Ulrich Sporlein. 229249729Sgshapiro Fix a regression introduced in 8.14.6: the wrong list of 230249729Sgshapiro macros was sent to a milter in the EHLO stage. 231249729Sgshapiro Problem found by Fabrice Bellet, reported via RedHat 232249729Sgshapiro (Jaroslav Skarvada). 233249729Sgshapiro Fix handling of ORCPT parameter for DSNs: xtext decoding 234249729Sgshapiro was not performed and a wrong syntax check was applied 235249729Sgshapiro to the "addr-type" field. Problem noted by Dan Lukes 236249729Sgshapiro of Obludarium. 237249729Sgshapiro Fix handling of NUL characters in the MIME conversion functions 238249729Sgshapiro so that message bodies containing them will be sent 239249729Sgshapiro on properly. Note: this usually also affects mails 240249729Sgshapiro that are not converted as those functions are used 241249729Sgshapiro for other purposes too. Problem noted by Elchonon 242249729Sgshapiro Edelson of Lockheed Martin. 243249729Sgshapiro Do not perform "duplicate" elimination of recipients if they 244249729Sgshapiro resolve to the error mailer using a temporary failure 245249729Sgshapiro (4xy) via ruleset 0.

Problem noted by Lena. 258244833Sgshapiro Do not cache hostnames internally in a non case sensitive way 259244833Sgshapiro as that may cause addresses to change from lower case 260244833Sgshapiro to upper case or vice versa. These header modifications 261244833Sgshapiro can cause problems with milters that rely on receiving 262244833Sgshapiro headers in the same way as they are being sent out such 263244833Sgshapiro as a DKIM signing milter. 264244833Sgshapiro If MaxQueueChildren is set then it was possible that new queue 265244833Sgshapiro runners could not be started anymore because an 266244833Sgshapiro internal counter was subject to a race condition. 267244833Sgshapiro If a milter decreases the timeout it waits for a communication 268244833Sgshapiro with the MTA, the MTA might experience a write() timeout. 269244833Sgshapiro In some situations, the resulting error might have been 270244833Sgshapiro ignored. Problem noted by Werner Wiethege. 271244833Sgshapiro Note: decreasing the communication timeout in a milter 272244833Sgshapiro should not be done without considering the potential 273244833Sgshapiro problems. 274244833Sgshapiro smfi_setsymlist() now properly sets the list of macros for 275244833Sgshapiro the milter which invoked it, instead of a global 276244833Sgshapiro list for all milters. Problem reported by 277244833Sgshapiro David Shrimpton of the University of Queensland. 278244833Sgshapiro If Timeout.resolver.retrans is set to a value larger than 20, 279244833Sgshapiro then resolver.retry was temporarily set to 0 for 280244833Sgshapiro gethostbyaddr() lookups. Now it is set to 1 instead. 281244833Sgshapiro Patch from Peter. 282244833Sgshapiro If sendmail could not lock the statistics file due to a system 283244833Sgshapiro error, and sendmail later sends a DSN for a mail that 284244833Sgshapiro triggered such an error, then sendmail tried to access 285244833Sgshapiro memory that was freed before (causing a crash on some 286244833Sgshapiro systems). Problem reported by Ryan Stone. 287244833Sgshapiro Do not log negative values for size= nor pri= to avoid confusing 288244833Sgshapiro log parsers, instead limit the values to LONG_MAX. 289244833Sgshapiro Account for an API change in newer versions of Cyrus-SASL. 290244833Sgshapiro Patch from Hajimu UMEMOTO from FreeBSD. 291244833Sgshapiro Do not try to resolve link-local addresses for IPv4 (just as it 292244833Sgshapiro is done for IPv6). Patch from John Beck of Oracle. 293244833Sgshapiro Improve logging of client and server STARTTLS connection failures 294244833Sgshapiro that may be due to incompatible cipher lists by including 295244833Sgshapiro the reason for the failure in a single log line. Suggested 296244833Sgshapiro by James Carey of Boeing. 297244833Sgshapiro Portability: 298261363Sgshapiro Add support for Darwin 11.x (Mac OS X 10.7). 299244833Sgshapiro Add support for SunOS 5.12 (aka Solaris 12).

Based on a 313223067Sgshapiro patch from Dr. Werner Fink of SuSE. 314223067Sgshapiro If a job is aborted using the interrupt signal (e.g., control-C from 315223067Sgshapiro the keyboard), perform minimal cleanup to avoid invoking 316223067Sgshapiro functions that are not signal-safe. Note: in previous 317223067Sgshapiro versions the mail might have been queued up already 318223067Sgshapiro and would be delivered subsequently, now an interrupt 319223067Sgshapiro will always remove the queue files and thus prevent 320223067Sgshapiro delivery. 321223067Sgshapiro Per RFC 6176, when operating as a TLS client, do not offer SSLv2. 322223067Sgshapiro Since TLS session resumption is never used as a client, disable 323223067Sgshapiro use of RFC 4507-style session tickets. 324223067Sgshapiro Work around gcc4 versions which reverse 25 years of history and 325223067Sgshapiro no longer align char buffers on the stack, breaking calls 326223067Sgshapiro to resolver functions on strict alignment platforms. 327223067Sgshapiro Found by Stuart Henderson of OpenBSD. 328223067Sgshapiro Read at most two AUTH lines from a server greeting (up to two 329223067Sgshapiro lines are read because servers may use "AUTH mechs" and 330223067Sgshapiro "AUTH=mechs"). Otherwise a malicious server may exhaust 331223067Sgshapiro the memory of the client. Bug report by Nils of MWR 332223067Sgshapiro InfoSecurity. 333223067Sgshapiro Avoid triggering an assertion in the OpenLDAP code when the 334223067Sgshapiro connection to an LDAP server is lost while making a query. 335223067Sgshapiro Problem noted and patch provided by Andy Fiddaman. 336223067Sgshapiro If ConnectOnlyTo is set and sendmail is compiled with NETINET6 337223067Sgshapiro it would try to use an IPv6 address if an IPv4 (or 338223067Sgshapiro unparseable) address is specified. 339223067Sgshapiro If SASLv2 is used, make sure that the macro {auth_authen} is 340223067Sgshapiro stored in xtext format to avoid problems with parsing 341223067Sgshapiro it. Problem noted by Christophe Wolfhugel. 342223067Sgshapiro CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing 343223067Sgshapiro -T<TMPF> that is required, but failed for some cases 344223067Sgshapiro that did not use LDAP. This change has been undone 345223067Sgshapiro until a better solution can be implemented. Problem 346223067Sgshapiro found by Andy Fiddaman. 347223067Sgshapiro CONFIG: Add cf/ostype/solaris11.m4 for Solaris11 support. 348223067Sgshapiro Contributed by Casper Dik of Oracle. 349223067Sgshapiro CONTRIB: qtool.pl: Deal with H entries that do not have a 350223067Sgshapiro letter between the question marks. Patch from 351223067Sgshapiro Stefan Christensen. 352223067Sgshapiro DOC: Use a better description for the -i option in sendmail. 353223067Sgshapiro Patch from Mitchell Berger. 354223067Sgshapiro Portability: 355223067Sgshapiro Add support for Darwin 10.x (Mac OS X 10.6). 356223067Sgshapiro Enable HAVE_NANOSLEEP for FreeBSD 3 and later. Patch 357223067Sgshapiro from John Marshall. 358223067Sgshapiro Enable HAVE_NANOSLEEP for OpenBSD 4.3 and later. 359223067Sgshapiro Use new directory "/system/volatile" for PidFile on 360223067Sgshapiro Solaris 11. Patch from Casper Dik of Oracle. 361223067Sgshapiro Fix compilation on Solaris 11 (and maybe some other 362223067Sgshapiro OSs) when using OpenSSL 1.0. Based on patch from 363223067Sgshapiro Jan Pechanec of Oracle. 364223067Sgshapiro Set SOCKADDR_LEN_T and SOCKOPT_LEN_T to socklen_t 365223067Sgshapiro for Solaris 11. Patch from Roger Faulkner of Oracle. 366223067Sgshapiro New Files: 367223067Sgshapiro cf/ostype/solaris11.m4 368223067Sgshapiro 369203004Sgshapiro8.14.4/8.14.4 2009/12/30 370203004Sgshapiro SECURITY: Handle bogus certificates containing NUL characters 371203004Sgshapiro in CNs by placing a string indicating a bad certificate 372203004Sgshapiro in the {cn_subject} or {cn_issuer} macro. Patch inspired 373203004Sgshapiro by Matthias Andree's changes for fetchmail. 374203004Sgshapiro During the generation of a queue identifier an integer overflow 375203004Sgshapiro could occur which might result in bogus characters 376203004Sgshapiro being used. Based on patch from John Vannoy of 377203004Sgshapiro Pepperdine University. 378203004Sgshapiro The value of headers, e.g., Precedence, Content-Type, et.al., 379203004Sgshapiro was not processed correctly. Patch from Per Hedeland. 380203004Sgshapiro Between 8.11.7 and 8.12.0 the length limitation on a return 381203004Sgshapiro path was erroneously reduced from MAXNAME (256) to 382203004Sgshapiro MAXSHORTSTR (203). Patch from John Gardiner Myers 383203004Sgshapiro of Proofpoint; the problem was also noted by Steve 384203004Sgshapiro Hubert of University of Washington. 385203004Sgshapiro Prevent a crash when a hostname lookup returns a seemingly 386203004Sgshapiro valid result which contains a NULL pointer (this seems 387203004Sgshapiro to be happening on some Linux versions). 388203004Sgshapiro The process title was missing the current load average when 389203004Sgshapiro the MTA was delaying connections due to DelayLA. 390203004Sgshapiro Patch from Dick St.Peters of NetHeaven. 391203004Sgshapiro Do not reset the number of queue entries in shared memory if 392203004Sgshapiro only some of them are processed. 393203004Sgshapiro Fix overflow of an internal array when parsing some replies 394203004Sgshapiro from a milter. Problem found by Scott Rotondo 395203004Sgshapiro of Sun Microsystems. 396203004Sgshapiro If STARTTLS is turned off in the server (via M=S) then it 397203004Sgshapiro would not be initialized for use in the client either. 398203004Sgshapiro Patch from Kazuteru Okahashi of IIJ. 399203004Sgshapiro If a Diffie-Hellman cipher is selected for STARTTLS, the 400203004Sgshapiro handshake could fail with some TLS implementations 401203004Sgshapiro because the prime used by the server is not long enough. 402203004Sgshapiro Note: the initialization of the DSA/DH parameters for 403203004Sgshapiro the server can take a significant amount of time on slow 404203004Sgshapiro machines. This can be turned off by setting DHParameters 405203004Sgshapiro to none or a file (see doc/op/op.me). Patch from 406203004Sgshapiro Petr Lampa of the Brno University of Technology. 407203004Sgshapiro Fix handling of `b' modifier for DaemonPortOptions on little 408203004Sgshapiro endian machines for loopback address. Patch from 409203004Sgshapiro John Beck of Sun Microsystems. 410203004Sgshapiro Fix a potential memory leak in libsmdb/smdb1.c found by parfait. 411203004Sgshapiro Based on patch from Jonathan Gray of OpenBSD. 412203004Sgshapiro If a milter sets the reply code to "421" during the transfer 413203004Sgshapiro of the body, the SMTP server will terminate the SMTP session 414203004Sgshapiro with that error to match the behavior of the other callbacks. 415203004Sgshapiro Return EX_IOERR (instead of 0) if a mail submission fails due to 416203004Sgshapiro missing disk space in the mail queue. Based on patch 417203004Sgshapiro from Martin Poole of RedHat. 418203004Sgshapiro CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would 419203004Sgshapiro cause addresses not found in LDAP to be misparsed. 420203004Sgshapiro CONFIG: Using a CN restriction did not work for TLS_Clt as it 421203004Sgshapiro referred to a wrong macro. Patch from John Gardiner 422203004Sgshapiro Myers of Proofpoint. 423203004Sgshapiro CONFIG: The option relaytofulladdress of FEATURE(`access_db') 424203004Sgshapiro did not work if FEATURE(`relay_hosts_only') is used too. 425203004Sgshapiro Problem noted by Kristian Shaw. 426203004Sgshapiro CONFIG: The internal function lower() was broken and hence 427203004Sgshapiro strcasecmp() did not work either, which could cause 428203004Sgshapiro problems for some FEATURE()s if upper case arguments 429203004Sgshapiro were used. Patch from Vesa-Matti J Kari of the 430203004Sgshapiro University of Helsinki. 431203004Sgshapiro LIBMILTER: Fix internal check whether a milter application 432203004Sgshapiro is compiled against the same version of libmilter as 433203004Sgshapiro it is linked against (especially useful for dynamic 434203004Sgshapiro libraries). 435203004Sgshapiro LIBMILTER: Fix memory leak that occurred when smfi_setsymlist() 436203004Sgshapiro was used. Based on patch by Dan Lukes. 437203004Sgshapiro LIBMILTER: Document the effect of SMFIP_HDR_LEADSPC for filters 438203004Sgshapiro which add, insert, or replace headers. From Benjamin 439203004Sgshapiro Pineau. 440203004Sgshapiro LIBMILTER: Fix error messages which refer to "select()" to be 441203004Sgshapiro correct if SM_CONF_POLL is used. Based on patch from 442203004Sgshapiro John Nemeth. 443203004Sgshapiro LIBSM: Fix handling of LDAP search failures where the error is 444203004Sgshapiro carried in the search result itself, such as seen with 445203004Sgshapiro OpenLDAP proxy servers. 446203004Sgshapiro VACATION: Do not refer to a local variable outside its scope. 447203004Sgshapiro Based on patch from Mark Costlow of Southwest Cyberport. 448203004Sgshapiro Portability: 449203004Sgshapiro Enable HAVE_NANOSLEEP for SunOS 5.11. Patch from 450203004Sgshapiro John Beck of Sun Microsystems. 451203004Sgshapiro Drop NISPLUS from default SunOS 5.11 map definitions. 452203004Sgshapiro Patch from John Beck of Sun Microsystems. 453203004Sgshapiro 454182352Sgshapiro8.14.3/8.14.3 2008/05/03 455182352Sgshapiro During ruleset processing the generation of a key for a map 456182352Sgshapiro lookup and the parsing of the default value was broken 457182352Sgshapiro for some macros, e.g., $|, which caused the BlankSub 458182352Sgshapiro character to be inserted into the workspace and thus 459182352Sgshapiro failures, e.g., rules that should have matched did not. 460182352Sgshapiro 8.14.2 caused a regression: it accessed (macro) storage which was 461182352Sgshapiro freed before. First instance of the problem reported by 462182352Sgshapiro Matthew Dillon of DragonFlyBSD; variations of the same 463182352Sgshapiro bug reported by Todd C. Miller of OpenBSD, Moritz 464182352Sgshapiro Jodeit, and Dave Hayes. 465182352Sgshapiro Improve pathname length checks for persistent host status. Patch 466182352Sgshapiro from Joerg Sonnenberger of DragonFlyBSD. 467182352Sgshapiro Reword misleading SMTP reply text for FEATURE(`badmx'). Problem 468182352Sgshapiro noted by Beth Halsema. 469182352Sgshapiro The read timeout was fixed to be Timeout.datablock if STARTTLS 470182352Sgshapiro was activated. This may cause problems if that value 471182352Sgshapiro is lowered from its default. Problem noted by Jens Elkner. 472182352Sgshapiro CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset 473182352Sgshapiro to operate incorrectly. Problem found by Werner Wiethege. 474182352Sgshapiro LIBMILTER: Omitting some protocol steps via the xxfi_negotiate() 475182352Sgshapiro callback did not work properly. The patchlevel of 476182352Sgshapiro libmilter has been set to 1 so a milter can determine 477182352Sgshapiro whether libmilter contains this fix. 478182352Sgshapiro MAKEMAP: If a delimiter is specified (-t) use that also when 479182352Sgshapiro dumping a map. Patch from Todd C. Miller of OpenBSD. 480182352Sgshapiro Portability: 481182352Sgshapiro Add support for Darwin 9.x (Mac OS X 10.5). 482182352Sgshapiro Support shared libraries in Darwin 8 and 9. Patch from 483182352Sgshapiro Chris Behrens of Concentric. 484182352Sgshapiro Add support for SCO OpenServer 6, patch from Boyd Gerber. 485203004Sgshapiro DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing slash. 486182352Sgshapiro Added Files: 487182352Sgshapiro devtools/OS/Darwin.9.x 488182352Sgshapiro devtools/OS/OSR.i386 489182352Sgshapiro 490173340Sgshapiro8.14.2/8.14.2 2007/11/01 491173340Sgshapiro If a message was queued and it contained 8 bit characters in 492173340Sgshapiro a From: or To: header, then those characters could be 493173340Sgshapiro "mistaken" for internal control characters during a queue 494173340Sgshapiro run and trigger various consistency checks. Problem 495173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 496173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 497173340Sgshapiro it is by default) then even if the Linelimit parameter 498173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 499173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 500173340Sgshapiro Myers of Proofpoint. 501173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 502173340Sgshapiro work in earlier 8.14 versions. 503173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 504173340Sgshapiro background if a milter can reject or delete a recipient. 505173340Sgshapiro Prior to 8.14 this happened only if milter could delete 506173340Sgshapiro recipients. 507173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 508182352Sgshapiro documented), not when it was reached. Patch from 509173340Sgshapiro John Beck of Sun Microsystems. 510173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 511173340Sgshapiro specified (R=0) and forking (F=f) is requested. 512173340Sgshapiro When multiple results are requested for a DNS map lookup 513173340Sgshapiro (-z and -Z), return only those that are relevant for 514173340Sgshapiro the query (not also those in the "additional section".) 515173340Sgshapiro If the message transfer time to sendmail (when acting as server) 516173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 517173340Sgshapiro the message is refused (by a milter), sendmail previously 518173340Sgshapiro created a delivery status notification (DSN). Patch 519173340Sgshapiro from Doug Heath of The Hertz Corporation. 520173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 521173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 522173340Sgshapiro Problem noted by Eliot Lear. 523173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 524173340Sgshapiro compiled in but not offered by the server and the 525173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 526173340Sgshapiro If getting the result of an LDAP query times out then close the 527173340Sgshapiro map so it will be reopened on the next lookup. This 528173340Sgshapiro should help "failover" configurations that specify more 529173340Sgshapiro than one LDAP server. 530173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 531173340Sgshapiro be triggered under some circumstances (e.g., requiring 532173340Sgshapiro a system which does not have the compile time flag 533173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 534173340Sgshapiro of National Institute of Informatics, Japan. 535173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 536173340Sgshapiro logfile entry might have been wrong. Problem found by 537173340Sgshapiro Petra Humann of TU Dresden. 538173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 539173340Sgshapiro NULL, the message body was lost. Patch from Motonori 540173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 541173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 542173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 543173340Sgshapiro replacing files. 544173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 545173340Sgshapiro reading the /etc/mail/virtusers/ directory. 546173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 547173340Sgshapiro appropriate. 548173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 549173340Sgshapiro against an older libmilter.so shared library can use an 550173340Sgshapiro 8.14 libmilter.so shared library. 551173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 552173340Sgshapiro from the version number, however, the returned value was 553173340Sgshapiro correct for the current libmilter version. 554173340Sgshapiro 555168515Sgshapiro8.14.1/8.14.1 2007/04/03 556168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 557168515Sgshapiro it in its list of recipients and deliver to it if the 558168515Sgshapiro transaction is accepted. This is a regression introduced 559168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 560168515Sgshapiro found by Andy Fiddaman. 561168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 562168515Sgshapiro could not be set in 8.14.0. 563168515Sgshapiro If a server shut down the connection in response to a STARTTLS 564168515Sgshapiro command, sendmail would log a misleading error message 565168515Sgshapiro due to an internal inconsistency. Problem found by 566168515Sgshapiro Werner Wiethege. 567168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 568168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 569168515Sgshapiro Science and Mathematics. 570168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 571168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 572168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 573168515Sgshapiro m4 options for setting MaxNOOPCommands and 574168515Sgshapiro SharedMemoryKeyFile. 575168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 576168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 577168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 578168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 579168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 580168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 581168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 582168515Sgshapiro negotiation. Problem reported by Bryan Costales. 583168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 584168515Sgshapiro Patches from Bryan Costales. 585168515Sgshapiro PORTABILITY FIXES: 586168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 587168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 588168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 589168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 590168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 591168515Sgshapiro Software Systems. 592168515Sgshapiro New Files: 593168515Sgshapiro devtools/M4/depend/QNX6.m4 594168515Sgshapiro devtools/OS/QNX.6.x 595168515Sgshapiro include/sm/os/sm_os_qnx.h 596168515Sgshapiro 597168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 598168515Sgshapiro libmilter/docs/smfi_chgfrom.html 599168515Sgshapiro libmilter/docs/smfi_version.html 600168515Sgshapiro 601168515Sgshapiro8.14.0/8.14.0 2007/01/31 602168515Sgshapiro Header field values are now 8 bit clean. Notes: 603168515Sgshapiro - header field names are still restricted to 7 bit. 604168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 605168515Sgshapiro headers. 606168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 607168515Sgshapiro number of spaces after the colon would be changed to 608168515Sgshapiro exactly one space. 609168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 610168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 611168515Sgshapiro limit may be reached too early, e.g., the counter 612168515Sgshapiro may be off by a factor of 4 in case of a sequence of 613168515Sgshapiro .forward files that refer to others. Patch from 614168515Sgshapiro Motonori Nakamura of Kyoto University. 615168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 616168515Sgshapiro "sendmail -bs" can trigger an assertion because the 617168515Sgshapiro hostname of the client is undefined. It is now set 618168515Sgshapiro to "localhost" for the xxfi_connect() callback. 619168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 620168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 621168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 622168515Sgshapiro Patch from Nik Clayton. 623168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 624168515Sgshapiro permanent errors (5xy). This can be useful for testing. 625168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 626168515Sgshapiro per daemon socket: 627168515Sgshapiro DeliveryMode DeliveryMode 628168515Sgshapiro refuseLA RefuseLA 629168515Sgshapiro delayLA DelayLA 630168515Sgshapiro queueLA QueueLA 631168515Sgshapiro children MaxDaemonChildren 632168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 633168515Sgshapiro lookup key with the LDAP escaped contents of the 634168515Sgshapiro arguments specified in the map lookup. Loosely based 635168515Sgshapiro on patch from Wolfgang Hottgenroth. 636168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 637168515Sgshapiro from Nik Clayton. 638168515Sgshapiro If a client is rejected via TCP wrapper or some other check 639168515Sgshapiro performed by validate_connection() (in conf.c) then do 640168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 641168515Sgshapiro of the University of Illinois at Urbana-Champaign. 642168515Sgshapiro If a client terminates the SMTP connection during a pause 643168515Sgshapiro introduced by greet_pause, then a misleading message 644168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 645168515Sgshapiro et.al., patch from Matej Vela. 646168515Sgshapiro New command "mstat" for control socket to provide "machine 647168515Sgshapiro readable" status. 648168515Sgshapiro New named config file rule check_eom which is called at the end 649168515Sgshapiro of a message, its parameter is the size of the message. 650168515Sgshapiro If the macro {addr_type} indicates that the current address 651168515Sgshapiro is a header address it also distinguishes between 652168515Sgshapiro recipient and sender addresses (as it is done for 653168515Sgshapiro envelope addresses). 654168515Sgshapiro When a macro is set in check_relay, then its value is accessible 655168515Sgshapiro by all transactions in the same SMTP session. 656168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 657168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 658168515Sgshapiro number of "useless" commands before the SMTP server will 659168515Sgshapiro slow down responding. 660168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 661168515Sgshapiro enabled, the MTA can be asked to select a shared memory 662168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 663168515Sgshapiro a file where to store the selected key. 664168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 665168515Sgshapiro by recognizing some commands from them. If the first command 666168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 667168515Sgshapiro connection is terminated immediately. 668168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 669168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 670168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 671168515Sgshapiro New options B, z, and Z for DNS maps: 672168515Sgshapiro -B: specify a domain that is always appended to queries. 673168515Sgshapiro -z: specify the delimiter at which to cut off the result of 674168515Sgshapiro a query if it is too long. 675168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 676168515Sgshapiro to form the result of a lookup. 677168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 678168515Sgshapiro implicitly while building libsm, they must be explicitly 679168515Sgshapiro started by using "make check". 680168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 681168515Sgshapiro reported by the SATURN tool which has been developed by 682168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 683168515Sgshapiro Fix a potential race condition caused by a signal handler for 684168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 685168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 686168515Sgshapiro queue group selection. This has been disabled as it was not 687168515Sgshapiro intended. 688168515Sgshapiro New operator 'r' for the arith map to return a random number. 689168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 690168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 691168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 692168515Sgshapiro which may improve the communication performance on some 693168515Sgshapiro operating systems. Patch from John Gardiner Myers of 694168515Sgshapiro Proofpoint. 695168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 696168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 697168515Sgshapiro generate an additional blank line in the output as the last 698168515Sgshapiro line. 699168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 700168515Sgshapiro the "queue control process" (QCP) works now. 701168515Sgshapiro Increase the length of an input line to 12288 to deal with 702168515Sgshapiro really long lines during SMTP AUTH negotiations. 703168515Sgshapiro Problem noted by Werner Wiethege. 704168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 705168515Sgshapiro a missing initialization call for that case). Problem 706168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 707168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 708168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 709168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 710168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 711168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 712168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 713168515Sgshapiro the MTA will not attempt to open a statistics file on 714168515Sgshapiro each delivery. 715168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 716168515Sgshapiro clients whose IP address does not have proper reverse DNS. 717168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 718168515Sgshapiro and John Beck of Sun Microsystems. 719168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 720168515Sgshapiro clients which provide a HELO/EHLO argument which is either 721168515Sgshapiro unqualified, or is one of our own names (i.e., the server 722168515Sgshapiro name instead of the client name). Contributed by Neil 723168515Sgshapiro Rickert of Northern Illinois University and John Beck of 724168515Sgshapiro Sun Microsystems. 725168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 726168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 727168515Sgshapiro Based on contribution from William Dell Wisner. 728168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 729168515Sgshapiro the maximum line length of the smtp mailers. 730168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 731168515Sgshapiro to allow entries in the access map to be of the form 732168515Sgshapiro To:user@example.com RELAY 733168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 734168515Sgshapiro macros a milter should receive at those stages in the 735168515Sgshapiro SMTP dialogue. 736168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 737168515Sgshapiro for the HELO/EHLO command. 738168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 739168515Sgshapiro messages by using those values as second argument. 740168515Sgshapiro Patches from Nelson Fung. 741168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 742168515Sgshapiro ignores everything after it unless it is in quotes or 743168515Sgshapiro preceeded by a backslash. 744168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 745168515Sgshapiro directories, then it used for "make install" to create 746168515Sgshapiro the required installation directories. 747168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 748168515Sgshapiro executables (defaults to confCC). 749168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 750168515Sgshapiro has several changes which are listed below and documented 751168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 752168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 753168515Sgshapiro changed. It now refers only to the version of libmilter, 754168515Sgshapiro not to the protocol version (which is used only internally, 755168515Sgshapiro it is not user/milter-programmer visible). Additionally, 756168515Sgshapiro a version function smfi_version() has been introduced such 757168515Sgshapiro that a milter program can check the libmilter version also 758168515Sgshapiro at runtime which is useful if a shared library is used. 759168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 760168515Sgshapiro dynamically (i.e., at runtime) determine the available 761168515Sgshapiro protocol actions and features of the MTA and also to 762168515Sgshapiro specify which of these a milter wants to use. This allows 763168515Sgshapiro for more flexibility than hardcoding these flags in the 764168515Sgshapiro xxfi_flags field of the smfiDesc structure. 765168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 766168515Sgshapiro can act on the DATA command. 767168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 768168515Sgshapiro can receive also unknown SMTP commands. 769168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 770168515Sgshapiro can be used by the xxfi_header() callback provided the 771168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 772168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 773168515Sgshapiro xxfi_body() callback to skip over further body chunks 774168515Sgshapiro and directly advance to the xxfi_eom() callback. This 775168515Sgshapiro is useful if a milter can make a decision based on the 776168515Sgshapiro body chunks it already received without reading the entire 777168515Sgshapiro rest of the body and the milter wants to invoke functions 778168515Sgshapiro that are only available from the xxfi_eom() callback. 779168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 780168515Sgshapiro new recipients including ESMTP parameters. 781168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 782168515Sgshapiro envelope sender including ESMTP parameters. 783168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 784168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 785168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 786168515Sgshapiro a RCPT has been rejected can be checked by comparing the 787168515Sgshapiro value of the macro {rcpt_mailer} with "error". 788168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 789168515Sgshapiro wants to receive from the MTA for each protocol step 790168515Sgshapiro by invoking the function smfi_setsymlist() during option 791168515Sgshapiro negotiation. 792168515Sgshapiro LIBMILTER: A milter can receive header field values with all 793168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 794168515Sgshapiro protocol action. Also, if the flag is set then the MTA 795168515Sgshapiro does not add a leading space to headers that are added, 796168515Sgshapiro inserted, or replaced. 797168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 798168515Sgshapiro callback, the SMTP server will terminate the SMTP session 799168515Sgshapiro with that error to match the behavior of all other callbacks. 800168515Sgshapiro New Files: 801168515Sgshapiro cf/feature/badmx.m4 802168515Sgshapiro cf/feature/block_bad_helo.m4 803168515Sgshapiro cf/feature/require_rdns.m4 804168515Sgshapiro devtools/M4/UNIX/check.m4 805168515Sgshapiro include/sm/misc.h 806168515Sgshapiro include/sm/sendmail.h 807168515Sgshapiro include/sm/tailq.h 808168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 809168515Sgshapiro libmilter/docs/smfi_setsymlist.html 810168515Sgshapiro libmilter/docs/xxfi_data.html 811168515Sgshapiro libmilter/docs/xxfi_negotiate.html 812168515Sgshapiro libmilter/docs/xxfi_unknown.html 813168515Sgshapiro libmilter/example.c 814168515Sgshapiro libmilter/monitor.c 815168515Sgshapiro libmilter/worker.c 816168515Sgshapiro libsm/memstat.c 817168515Sgshapiro libsm/t-memstat.c 818168515Sgshapiro libsm/t-qic.c 819168515Sgshapiro libsm/util.c 820168515Sgshapiro sendmail/daemon.h 821168515Sgshapiro sendmail/map.h 822168515Sgshapiro 823161389Sgshapiro8.13.8/8.13.8 2006/08/09 824161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 825161389Sgshapiro the server can erroneously report that there is 826161389Sgshapiro insufficient disk space. Additionally make sure that 827161389Sgshapiro an internal variable is set properly to avoid those 828161389Sgshapiro misleading errors. Based on patch from Steve Hubert 829161389Sgshapiro of University of Washington. 830161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 831161389Sgshapiro the process that forks the daemon exited, i.e., if 832161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 833161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 834161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 835161389Sgshapiro David F. Skoll. 836161389Sgshapiro Avoid a crash when finishing due to referencing a freed variable. 837161389Sgshapiro Problem reported and diagnosed by Moritz Jodeit. 838161389Sgshapiro CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4 839161389Sgshapiro range (0..255). 840161389Sgshapiro LIBMILTER: The "hostname" argument of the xxfi_connect() callback 841161389Sgshapiro previously was the equivalent of {client_ptr}. However, 842161389Sgshapiro this did not match the documentation of the function, hence 843285303Sgshapiro it has been changed to {client_name}. See doc/op/op.me 844161389Sgshapiro about these macros. 845161389Sgshapiro 846159609Sgshapiro8.13.7/8.13.7 2006/06/14 847159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 848159609Sgshapiro crash while trying to send a mail due to a stack overflow, 849159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 850159609Sgshapiro happens because the recursion of the function mime8to7() 851159609Sgshapiro was not restricted. The function is called for MIME 8 to 852159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 853159609Sgshapiro To work around this problem, recursive calls are limited to 854159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 855159609Sgshapiro limit is treated as opaque and is not checked further. 856159609Sgshapiro Problem noted by Frank Sheiness. 857159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 858159609Sgshapiro SASL mechanisms that use the security layer, e.g., 859159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 860159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 861159609Sgshapiro a df file might have been left behind in the queue. 862159609Sgshapiro This was another side effect of the changes to the I/O 863159609Sgshapiro layer made in 8.13.6. 864159609Sgshapiro Several minor problems have been fixed that were found by a 865159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 866159609Sgshapiro distribution. See http://scan.coverity.com/ 867159609Sgshapiro Note: the scan generated also a lot of "false positives", 868159609Sgshapiro e.g., "error" reports about situations that cannot happen. 869159609Sgshapiro Most of those code places are marked with lint(1) comments 870159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 871159609Sgshapiro Hence an explicit assertion has been added in some cases 872159609Sgshapiro to avoid those false positives. 873159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 874159609Sgshapiro error then in some cases shared memory segments or pid 875159609Sgshapiro files were not removed. 876159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 877159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 878159609Sgshapiro reported by Akihiro Sagawa. 879159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 880159609Sgshapiro bug work-around. Hence if sendmail is linked against 881159609Sgshapiro either of these versions and compression is available, 882159609Sgshapiro the padding bug work-around is turned off. Based on 883159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 884159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 885159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 886159609Sgshapiro however, that list is no longer available. To avoid 887159609Sgshapiro further problems, no default value is available anymore, 888159609Sgshapiro but an argument must be specified. 889159609Sgshapiro Portability: 890159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c. Patch from 891159609Sgshapiro Pieter Bowman of the University of Utah. 892159609Sgshapiro 893157001Sgshapiro8.13.6/8.13.6 2006/03/22 894157001Sgshapiro SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server 895157001Sgshapiro and client side of sendmail with timeouts in the libsm I/O 896157001Sgshapiro layer and fix problems in that code. Also fix handling of 897157001Sgshapiro a buffer in sm_syslog() which could have been used as an 898157001Sgshapiro attack vector to exploit the unsafe handling of 899157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 900157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 901157001Sgshapiro Handle theoretical integer overflows that could triggered if 902157001Sgshapiro the server accepted headers larger than the maximum 903157001Sgshapiro (signed) integer value. This is prevented in the default 904157001Sgshapiro configuration by restricting the size of a header, and on 905157001Sgshapiro most machines memory allocations would fail before reaching 906157001Sgshapiro those values. Problems found by Phil Brass of ISS. 907157001Sgshapiro If a server returns 421 for an RSET command when trying to start 908157001Sgshapiro another transaction in a session while sending mail, do 909157001Sgshapiro not trigger an internal consistency check. Problem found 910157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 911157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 912157001Sgshapiro to a STARTTLS command despite the fact that it advertised 913157001Sgshapiro STARTTLS and that the code is not valid according to RFC 914157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 915157001Sgshapiro of a protocol error (which has been changed to a 916157001Sgshapiro temporary error in 8.13.5).

This structure is used decide whether there 948157001Sgshapiro is enough free disk space when selecting a queue, hence 949157001Sgshapiro without this change queue selection could fail if a df/ 950157001Sgshapiro subdirectory exists and is on a different filesystem 951157001Sgshapiro than the base directory. 952157001Sgshapiro Use the queue index of the df file (instead of the qf file) for 953157001Sgshapiro checking whether a link(2) operation can be used to split 954157001Sgshapiro an envelope across queue groups. Problem found by 955157001Sgshapiro Werner Wiethege. 956157001Sgshapiro If the list of items in the queue is larger than the maximum 957157001Sgshapiro number of items to process, sort the queue first and 958157001Sgshapiro then cut the list off instead of the other way around. 959157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 960157001Sgshapiro Fix helpfile to show full entry for ETRN. Problem noted by 961157001Sgshapiro Penelope Fudd, patch from Neil Rickert of Northern Illinois 962157001Sgshapiro University. 963157001Sgshapiro FallbackSmartHost should also be tried on temporary errors. 964157001Sgshapiro From John Beck of Sun Microsystems. 965157001Sgshapiro When a server responds with 421 to the STARTTLS command then treat 966157001Sgshapiro it as a temporary error, not as protocol error. Problem 967157001Sgshapiro noted by Andrey J. Melnikoff. 968157001Sgshapiro Properly define two functions in libsm as static because their 969157001Sgshapiro prototype used static too. Patch from Peter Klein. 970157001Sgshapiro Fix syntax errors in helpfile for MAIL and RCPT commands. 971157001Sgshapiro LIBMILTER: When smfi_replacebody() is called with bodylen equals 972157001Sgshapiro zero then do not silently ignore that call. Patch from 973157001Sgshapiro Gurusamy Sarathy of Active State. 974157001Sgshapiro LIBMILTER: Recognize "421" also in a multi-line reply to terminate 975157001Sgshapiro the SMTP session with that error. Fix from Brian Kantor. 976157001Sgshapiro Portability: New option HASSNPRINTF which can be set if the OS 977157001Sgshapiro has a properly working snprintf(3) to get rid 978157001Sgshapiro of the last two (safe) sprintf(3) calls in the 979157001Sgshapiro source code. 980157001Sgshapiro Add support for AIX 5.3. 981157001Sgshapiro Add support for SunOS 5.11 (aka Solaris 11). 982157001Sgshapiro Add support for Darwin 8.x.

Problem noted by Michael Sims. 1007147078Sgshapiro Deal with empty hostnames in hostsignature(). This bug could lead 1008147078Sgshapiro to an endless loop when doing LMTP deliveries to another 1009147078Sgshapiro host. Problem first reported by Martin Lathoud and 1010147078Sgshapiro tracked down by Gael Roualland. 1011147078Sgshapiro Make sure return parameters are initialized in getmxrr(). Problem 1012147078Sgshapiro found by Gael Roualland using valgrind. 1013147078Sgshapiro If shared memory is used and the RunAsUser option is set, then the 1014161389Sgshapiro owner and group of the shared memory segment is set to 1015147078Sgshapiro the ids specified RunAsUser and the access mode is set 1016147078Sgshapiro to 0660 to allow for updates by sendmail processes. 1017147078Sgshapiro The number of queue entries that is (optionally) kept in shared 1018147078Sgshapiro memory was wrong in some cases, e.g., envelope splitting 1019147078Sgshapiro and bounce generation. 1020147078Sgshapiro Undo a change made in 8.13.0 to silently truncate long strings 1021147078Sgshapiro in address rewriting because the message can be triggered 1022147078Sgshapiro for header checks where long strings are legitimate. 1023147078Sgshapiro Problem reported by Mary Verge DeSisto, and tracked 1024147078Sgshapiro down with the help of John Beck of Sun Microsystems. 1025147078Sgshapiro The internal stab map did not obey the -m flag. Patch from 1026147078Sgshapiro Rob McMahon of Warwick University, England. 1027147078Sgshapiro The socket map did not obey the -f flag. Problem noted by 1028147078Sgshapiro Dan Ringdahl, forwarded by Andrzej Filip. 1029147078Sgshapiro The addition of LDAP recursion in 8.13.0 broke enforcement of 1030147078Sgshapiro the LDAP map -1 argument which tells the MTA to only 1031147078Sgshapiro return success if and only if a single LDAP match is found. 1032147078Sgshapiro Add additional error checks in the MTA for milter communication 1033147078Sgshapiro to avoid a possible segmentation fault. Based on patch 1034147078Sgshapiro by Joe Maimon. 1035147078Sgshapiro Do not trigger an assertion if X509_digest() returns success but 1036147078Sgshapiro does not assign a value to its output parameter. Based 1037147078Sgshapiro on patch by Brian Kantor. 1038147078Sgshapiro Add more checks when resetting internal AUTH data (applies only 1039147078Sgshapiro to Cyrus SASL version 2). Otherwise an SMTP session might 1040147078Sgshapiro be dropped after an AUTH failure. 1041147078Sgshapiro Portability: 1042147078Sgshapiro Add LA_LONGLONG as valid LA_TYPE type for systems that use 1043147078Sgshapiro "long long" to read load average data, e.g., 1044147078Sgshapiro AIX 5.1 in 32 bit mode. Note: this has to be set 1045147078Sgshapiro "by hand", it is not (yet) automatically detected. 1046147078Sgshapiro Problem noted by Burak Bilen. 1047147078Sgshapiro Use socklen_t for accept(), etc. on AIX 5.x. This should 1048147078Sgshapiro fix problems when compiling in 64 bit mode. 1049147078Sgshapiro Problem first reported by Harry Meiert of 1050147078Sgshapiro University of Bremen. 1051147078Sgshapiro New Files: 1052147078Sgshapiro include/sm/sem.h 1053147078Sgshapiro libsm/sem.c 1054147078Sgshapiro libsm/t-sem.c 1055147078Sgshapiro 1056141858Sgshapiro8.13.3/8.13.3 2005/01/11 1057141858Sgshapiro Enhance handling of I/O errors, especially EOF, when STARTTLS 1058141858Sgshapiro is active. 1059141858Sgshapiro Make sure a connection is not reused after it has been closed 1060141858Sgshapiro due to a 421 error. Problem found by Allan E Johannesen 1061141858Sgshapiro of Worcester Polytechnic Institute. 1062141858Sgshapiro Avoid triggering an assertion when sendmail is interrupted while 1063141858Sgshapiro closing a connection. Problem found by Allan E Johannesen 1064141858Sgshapiro of Worcester Polytechnic Institute. 1065141858Sgshapiro Regression: a change in 8.13.2 caused sendmail not to try the 1066141858Sgshapiro next MX host (or FallbackMXhost if configured) when, at 1067141858Sgshapiro connection open, the current server returns a 4xy or 5xy 1068141858Sgshapiro SMTP reply code.

Previously a part of such a header would 1073141858Sgshapiro end up in the body of the message. Problem noted by 1074141858Sgshapiro Simple Nomad of BindView. 1075141858Sgshapiro Do not complain about "cataddr: string too long" when checking 1076141858Sgshapiro headers that do not contain RFC 2822 addresses. 1077141858Sgshapiro Problem noted by Rich Graves of Brandeis University. 1078141858Sgshapiro If a server returns a 421 reply to the RSET command between 1079141858Sgshapiro message deliveries, do not attempt to deliver any more 1080141858Sgshapiro messages on that connection. This prevents bogus "Bad 1081141858Sgshapiro file number" recipient status. Problem noted by 1082141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 1083141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 1084141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 1085141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 1086141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 1087141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 1088141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 1089141858Sgshapiro them off at a comma.

Problem found 1172132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 1173132943Sgshapiro Add support for LDAP recursion based on types given to attribute 1174132943Sgshapiro specifications in an LDAP map definition. This allows 1175132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 1176132943Sgshapiro URL which will in turn be queried. See the ``LDAP 1177132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 1178132943Sgshapiro Based on patch from Andrew Baucom. 1179132943Sgshapiro Extend the default LDAP specifications for AliasFile 1180132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 1181132943Sgshapiro include support for LDAP recursion via new attributes. 1182132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 1183132943Sgshapiro of cf/README for more information. 1184132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 1185132943Sgshapiro LDAP API/protocol version to use. The default depends on 1186132943Sgshapiro the LDAP library. 1187132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 1188132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 1189132943Sgshapiro and -p port. This also allows for the use of LDAP over 1190132943Sgshapiro SSL and connections via named sockets if your LDAP 1191132943Sgshapiro library supports it. 1192132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 1193132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 1194132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 1195132943Sgshapiro during a SMTP session then terminate it just like it is 1196132943Sgshapiro done for too many bad SMTP commands. 1197132943Sgshapiro Basic connection rate control support has been added: the daemon 1198132943Sgshapiro maintains the number of incoming connections per client 1199132943Sgshapiro IP address and total in the macros {client_rate} and 1200132943Sgshapiro {total_rate}, respectively. These macros can be used 1201132943Sgshapiro in the cf file to impose connection rate limits. 1202132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 1203132943Sgshapiro determines the length of the interval for which the 1204132943Sgshapiro number of connections is stored. Based on patch from 1205132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 1206132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 1207132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 1208132943Sgshapiro If enabled by the new ruleset greet_pause (see 1209132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 1210132943Sgshapiro amount of time before sending the initial 220 SMTP 1211132943Sgshapiro greeting. If any traffic is received before then, a 554 1212132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 1213132943Sgshapiro during that connection. 1214132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 1215132943Sgshapiro server could sleep for a very long time. Fix based on 1216132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 1217132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 1218132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 1219132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 1220132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 1221132943Sgshapiro misinterpret it as a permanent error. 1222132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 1223132943Sgshapiro all milters accepted the mail. This can increase 1224132943Sgshapiro performance if many mails are rejected by milters due to 1225132943Sgshapiro body scans. Based on patch from David F. Skoll. 1226132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 1227132943Sgshapiro header, whether provided by the client or generated by 1228132943Sgshapiro sendmail. 1229132943Sgshapiro New macro {client_connections} which contains the number of open 1230132943Sgshapiro connections in the SMTP server for the client IP address. 1231132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 1232132943Sgshapiro Mines de Paris. 1233132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 1234132943Sgshapiro to prevent confusion caused by running sendmail stop 1235132943Sgshapiro scripts two or more times, where the second and subsequent 1236141858Sgshapiro runs would report misleading error messages about sendmail's 1237132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 1238132943Sgshapiro for a discussion of the implications of this, including 1239132943Sgshapiro how to correct broken scripts which may have depended on 1240132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 1241132943Sgshapiro Support per-daemon input filter lists which override the default 1242132943Sgshapiro filter list specified in InputMailFilters. The filters 1243132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 1244132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 1245132943Sgshapiro your configuration relies on this behavior, you have to 1246132943Sgshapiro add those names to class 'w' yourself. Problem noted 1247132943Sgshapiro by Sander Eerkes. 1248132943Sgshapiro Support message quarantining in the mail queue. Quarantined 1249132943Sgshapiro messages are not run on normal queue displays or runs 1250132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 1251132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 1252132943Sgshapiro The -q command line option now can specify which queue to display 1253132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 1254132943Sgshapiro operates on lost queue items. 1255132943Sgshapiro Restricted mail queue runs and displays can be done based on the 1256132943Sgshapiro quarantined reason using -qQtext to run or display 1257132943Sgshapiro quarantined items if the quarantine reason contains the 1258132943Sgshapiro given text. Similarly, -q!Qtext will run or display 1259132943Sgshapiro quarantined items which do not have the given text in the 1260132943Sgshapiro quarantine reason. 1261132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 1262132943Sgshapiro new -Q option. See doc/op/op.me for more information. 1263132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 1264132943Sgshapiro quarantine reason is shown in a new line prefixed by 1265132943Sgshapiro "QUARANTINE:". 1266132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 1267132943Sgshapiro to quarantine messages in check_* (except check_compat) and 1268132943Sgshapiro header check rulesets. The $: of the mailer triplet will 1269132943Sgshapiro be used for the quarantine reason. 1270132943Sgshapiro Add a new quarantine count to the mailstats collected. 1271132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 1272132943Sgshapiro message if it is quarantined. 1273132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 1274132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 1275132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 1276132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 1277132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 1278132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 1279132943Sgshapiro lookup for the client IP address. Note: this is the same 1280132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 1281132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 1282132943Sgshapiro recipients received so far in a transaction. 1283132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 1284132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 1285132943Sgshapiro noted by Kai Schlichting. 1286132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 1287132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 1288132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 1289132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 1290132943Sgshapiro Wolfhugel of France Telecom Oleane. 1291132943Sgshapiro Do not silently truncate long strings in address rewriting. 1292132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 1293132943Sgshapiro Oceana Matrix Ltd. 1294132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 1295132943Sgshapiro support mutual authentication. From Kenneth Murchison of 1296132943Sgshapiro Oceana Matrix Ltd. 1297132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 1298132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 1299132943Sgshapiro format just like the STARTTLS related macros to avoid 1300132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 1301132943Sgshapiro Masarati of SysNet s.n.c. 1302132943Sgshapiro New option AuthRealm to set the authentication realm that is 1303132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 1304132943Sgshapiro of the University of Manitoba. 1305132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 1306132943Sgshapiro successful, otherwise relaying would be allowed if 1307132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 1308132943Sgshapiro is active. 1309132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 1310132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 1311132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 1312132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 1313132943Sgshapiro DIGEST-MD5 and LOGIN. 1314132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 1315132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 1316132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 1317132943Sgshapiro overwrite each other's pid files. 1318132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 1319132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 1320132943Sgshapiro Wolfhugel of France Telecom. 1321132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 1322132943Sgshapiro LogLevel 12 or higher. 1323132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 1324132943Sgshapiro try to use the SMTP command VERB to propagate this option 1325132943Sgshapiro to the MTA which in turn will show the delivery just like 1326132943Sgshapiro it was done before the default 8.12 separation of MSP and 1327132943Sgshapiro MTA. Based on patch by Per Hedeland. 1328132943Sgshapiro If a daemon is refusing connections for longer than the time specified 1329132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 1330132943Sgshapiro to high load, log this information. Patch from John Beck 1331132943Sgshapiro of Sun Microsystems. 1332132943Sgshapiro Remove the ability for non-trusted users to raise the value of 1333132943Sgshapiro CheckpointInterval on the command line. 1334132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 1335132943Sgshapiro subset of the functionality of the 's' flag. 1336132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 1337132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 1338132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 1339132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 1340132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 1341132943Sgshapiro causing subsequent messages to be sent instead of being 1342132943Sgshapiro discarded. This also caused milter callbacks to be called 1343132943Sgshapiro out of order after the SMTP session was reset. 1344132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 1345132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 1346132943Sgshapiro further information. 1347132943Sgshapiro New command line option -D logfile to send debug output to 1348132943Sgshapiro the indicated log file instead of stdout. 1349132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 1350132943Sgshapiro queue return and warning times for delivery status 1351132943Sgshapiro notifications. 1352132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 1353132943Sgshapiro at all. 1354132943Sgshapiro Several more return values for ruleset srv_features have been added 1355132943Sgshapiro to enable/disable certain features in the server per 1356132943Sgshapiro connection. See doc/op/op.me for details. 1357132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 1358132943Sgshapiro for DaemonPortOptions. 1359132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 1360132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 1361132943Sgshapiro of Northern Illinois University. 1362132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 1363132943Sgshapiro be tried as a last resort after all other fallbacks. This 1364132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 1365132943Sgshapiro view of inside the company, but an incomplete view of 1366132943Sgshapiro outside). From John Beck of Sun Microsystems. 1367132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 1368132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 1369132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 1370132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 1371132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 1372132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 1373132943Sgshapiro of the University of Illinois at Urbana-Champaign. 1374132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 1375132943Sgshapiro applications for use in the xxfi_eom() callback. 1376132943Sgshapiro New macro {time} which contains the output of the time(3) function, 1377132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 1378132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 1379132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 1380132943Sgshapiro terminate the SMTP session with a 421 error message. 1381132943Sgshapiro Get rid of dead code that tried to access the environment variable 1382132943Sgshapiro HOSTALIASES. 1383132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 1384132943Sgshapiro compile with -DUSE_TTYPATH=1. 1385132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 1386132943Sgshapiro the header value passed in without balancing quotes, 1387132943Sgshapiro parentheses, and angle brackets. Based on patch from 1388132943Sgshapiro Oleg Bulyzhin. 1389132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 1390132943Sgshapiro angle brackets when reading in rulesets. This allows 1391132943Sgshapiro rules to be written for header checks to catch strings 1392132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 1393132943Sgshapiro Based on patch from Oleg Bulyzhin. 1394132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 1395132943Sgshapiro some temporary errors like ECONNABORTED. 1396132943Sgshapiro Added list of CA certificates that are used by members of the 1397132943Sgshapiro sendmail consortium, see CACerts. 1398132943Sgshapiro Portability: 1399132943Sgshapiro Two new compile options have been added: 1400132943Sgshapiro HASCLOSEFROM System has closefrom(3). 1401132943Sgshapiro HASFDWALK System has fdwalk(3). 1402132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 1403132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 1404132943Sgshapiro change to using fcntl() locking until they can fix 1405132943Sgshapiro it. Be sure to update other sendmail related 1406132943Sgshapiro programs to match locking techniques. 1407132943Sgshapiro New compile time option NEEDINTERRNO which should be set 1408132943Sgshapiro if <errno.h> does not declare errno itself. 1409132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 1410132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 1411132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 1412132943Sgshapiro Center for Scientific Computing. 1413132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 1414132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 1415132943Sgshapiro Remove path from compiler definition for Interix because 1416132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 1417132943Sgshapiro Also use <sys/mkdev.h> to get the correct 1418132943Sgshapiro major()/minor() definitions. Based on feedback 1419132943Sgshapiro from Mark Funkenhauser. 1420132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 1421132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 1422132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 1423132943Sgshapiro cf/sendmail.schema for more information. 1424132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 1425132943Sgshapiro is of the form "user:group" when used for submit.mc. 1426132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 1427132943Sgshapiro of Northern Illinois University. 1428132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 1429132943Sgshapiro instructs the check_* (except check_compat) to quarantine 1430132943Sgshapiro the message using the given reason. 1431132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 1432132943Sgshapiro instead of "host" to avoid problem with looking up other 1433132943Sgshapiro DNS records than just A. 1434132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 1435132943Sgshapiro length of the interval for which the number of incoming 1436132943Sgshapiro connections is maintained. 1437132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 1438132943Sgshapiro rate control for individual hosts or nets. 1439132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 1440132943Sgshapiro number of open SMTP connections for individual hosts or nets. 1441132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 1442132943Sgshapiro slamming protection described above. The feature can 1443132943Sgshapiro take an argument specifying the milliseconds to wait and/or 1444132943Sgshapiro use the access database to look the pause time based on 1445132943Sgshapiro client hostname, domain, IP address, or subnet. 1446132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 1447132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 1448132943Sgshapiro rejections based on the unverified hostname of client, 1449132943Sgshapiro which turns on the same behavior as in earlier sendmail 1450132943Sgshapiro versions when delay_checks was not in use. See also entry 1451132943Sgshapiro above about check_relay being invoked with ${client_name}. 1452132943Sgshapiro CONFIG: New option confREJECT_LOG_INTERVAL to specify the log 1453132943Sgshapiro interval when refusing connections for this long. 1454132943Sgshapiro CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases 1455132943Sgshapiro this requires a change in a mc file. Requested by 1456132943Sgshapiro Ted Roberts of Electronic Data Systems. 1457132943Sgshapiro CONFIG: New option confAUTH_REALM to set the authentication realm 1458132943Sgshapiro that is passed to the Cyrus SASL library. Patch from 1459132943Sgshapiro Gary Mills of the University of Manitoba. 1460132943Sgshapiro CONFIG: Rename the (internal) classes {tls}/{src} to {Tls}/{Src} 1461132943Sgshapiro to follow the naming conventions. 1462132943Sgshapiro CONFIG: Add a third optional argument to local_lmtp to specify 1463132943Sgshapiro the A= argument. 1464132943Sgshapiro CONFIG: Remove the f flag from the default mailer flags of 1465132943Sgshapiro local_lmtp. 1466132943Sgshapiro CONFIG: New option confREQUIRES_DIR_FSYNC to turn off the compile 1467132943Sgshapiro time flag REQUIRES_DIR_FSYNC at runtime. 1468132943Sgshapiro CONFIG: New LOCAL_UUCP macro to insert rules into the generated 1469132943Sgshapiro cf file at the same place where MAILER(`uucp') inserts 1470132943Sgshapiro its rules. 1471132943Sgshapiro CONFIG: New options confTO_QUEUERETURN_DSN and confTO_QUEUEWARN_DSN 1472132943Sgshapiro to control queue return and warning times for delivery 1473132943Sgshapiro status notifications. 1474132943Sgshapiro CONFIG: New option confFALLBACK_SMARTHOST to define FallbackSmartHost. 1475132943Sgshapiro CONFIG: Add the mc file which has been used to create the cf 1476132943Sgshapiro file to the end of the cf file when using make in cf/cf/. 1477132943Sgshapiro Patch from Richard Rognlie. 1478132943Sgshapiro CONFIG: FEATURE(nodns) has been removed, it was a no-op since 8.9. 1479132943Sgshapiro Use ServiceSwitchFile to turn off DNS lookups, see 1480132943Sgshapiro doc/op/op.me. 1481132943Sgshapiro CONFIG: New option confMILTER_MACROS_EOM (sendmail Milter.macros.eom 1482132943Sgshapiro option) defines macros to be sent to milter applications for 1483132943Sgshapiro use in the xxfi_eom() callback. 1484132943Sgshapiro CONFIG: New option confCRL to specify file which contains 1485132943Sgshapiro certificate revocations lists. 1486132943Sgshapiro CONFIG: Add a new value (sendertoo) for the third argument to 1487132943Sgshapiro FEATURE(`ldap_routing') which will reject the SMTP 1488132943Sgshapiro MAIL From: command if the sender address doesn't exist 1489132943Sgshapiro in LDAP. See cf/README for more information. 1490132943Sgshapiro CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which 1491132943Sgshapiro instructs the rulesets on whether or not to do a domain 1492132943Sgshapiro lookup if a full address lookup doesn't match. See cf/README 1493132943Sgshapiro for more information. 1494132943Sgshapiro CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which 1495132943Sgshapiro instructs the rulesets on whether or not to queue the mail 1496132943Sgshapiro or give an SMTP temporary error if the LDAP server can't be 1497132943Sgshapiro reached. See cf/README for more information.

Problem noted by Andrzej Filip. 1617125820Sgshapiro Some ident responses contain data after the terminating CRLF which 1618125820Sgshapiro causes sendmail to log "POSSIBLE ATTACK...newline in string". 1619125820Sgshapiro To avoid this everything after LF is ignored. 1620125820Sgshapiro If the operating system supports O_EXLOCK and HASFLOCK is set 1621125820Sgshapiro then a possible race condition for creating qf files 1622125820Sgshapiro can be avoided. Note: the race condition does not 1623125820Sgshapiro exist within sendmail, but between sendmail and an 1624125820Sgshapiro external application that accesses qf files. 1625125820Sgshapiro Log the proper options name for TLS related mising files for 1626125820Sgshapiro the CACertPath, CACertFile, and DHParameters options. 1627125820Sgshapiro Do not split an envelope if it will be discarded, otherwise df 1628125820Sgshapiro files could be left behind.

This change has been made to 1936102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 1937102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 1938102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1939102528Sgshapiro modification causes a change of behavior if an IP net/address 1940102528Sgshapiro is listed in the access map with REJECT and a host/domain 1941102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1942102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1943102528Sgshapiro change was made on request of Neil Rickert of Northern 1944102528Sgshapiro Illinois University, the side effect has been found by 1945102528Sgshapiro Stefaan Van Hoornick. 1946102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1947102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1948102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1949102528Sgshapiro University. 1950102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1951102528Sgshapiro Fix from Andrzej Filip. 1952102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1953102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1954102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1955102528Sgshapiro NULL pointer.

In previous versions this could cause mail 209294334Sgshapiro not to be delivered if a queue file is repeatedly moved 209394334Sgshapiro by an external process whenever sendmail moved it back 209494334Sgshapiro into the right place. Some precautions have been taken 209594334Sgshapiro to avoid moving queue files if not really necessary. 209694334Sgshapiro sendmail may use links to refer to queue files and it 209794334Sgshapiro may store the path of data files in queue files. Hence 209894334Sgshapiro queue files should not be moved unless those internals 209994334Sgshapiro are understood and the integrity of the files is not 210094334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 210194334Sgshapiro University. 210294334Sgshapiro If an error mail is created, and the mail is split across different 210394334Sgshapiro queue directories, and SuperSafe is off, then write the mail 210494334Sgshapiro to disk before splitting it, otherwise an assertion is 210594334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 210694334Sgshapiro of INTERMETA. 210794334Sgshapiro Fix possible race condition that could cause sendmail to forget 210894334Sgshapiro running queues.

Based on patch from Dirk Meyer 212194334Sgshapiro of Dinoex. 212294334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 212394334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 212494334Sgshapiro Polytechnic Institute. 212594334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 212694334Sgshapiro if several mails are sent in one session and some of them 212794334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 212894334Sgshapiro Change timeout check such that cached information about a connection 212994334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 213094334Sgshapiro Based on patch from David Burns of Portland State University. 213194334Sgshapiro Properly count message size for mailstats during mail collection. 213294334Sgshapiro Problem noted by Werner Wiethege. 213394334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 2134168515Sgshapiro patch from Motonori Nakamura of Kyoto University. 213594334Sgshapiro Provide workaround for getopt() implementations that do not catch 213694334Sgshapiro missing arguments. 213794334Sgshapiro Fix the message size calculation if the message body is replaced by 213894334Sgshapiro a milter filter and buffered file I/O is being used. 213994334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 214094334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 214194334Sgshapiro Problem noted by Werner Wiethege. 214294334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 214394334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 214494334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 214594334Sgshapiro Properly deal with a case where sendmail is called by root running 214694334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 214794334Sgshapiro Lusky of ISS Atlanta. 214894334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 214994334Sgshapiro directories are used and mail is sent to a mailing list 215094334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 215194334Sgshapiro of Concordia University. 215294334Sgshapiro Fix class map parsing code if optional key is specified. Problem 215394334Sgshapiro found by Mario Nigrovic. 215494334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 215594334Sgshapiro incoming messages. A leading dot is always stripped by the 215694334Sgshapiro SMTP receiver regardless of whether or not it is followed by 215794334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 215894334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 215994334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 216094334Sgshapiro Elvers. 216194334Sgshapiro Correct the statistics gathered for total number of connections. 216294334Sgshapiro Instead of being the exact same number as the total number 216394334Sgshapiro of messages (T line in mailstats) it now represents the 216494334Sgshapiro total number of TCP connections. 216594334Sgshapiro Be more explicit about syntax errors in addresses, especially 216694334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 216794334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 216894334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 216994334Sgshapiro are used.

Based on 217794334Sgshapiro patch by Bryan Costales. 217894334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 217994334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 218094334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 218194334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 218294334Sgshapiro errors. By doing so, the host was marked as having a 218394334Sgshapiro temporary problem and other mail destined for that host was 218494334Sgshapiro queued for the next queue run. Problem noted by Fletcher 218594334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 218694334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 218794334Sgshapiro and Neil Rickert of Northern Illinois University. 218894334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 218994334Sgshapiro which drop the connection instead of responding to the 219094334Sgshapiro command). 219194334Sgshapiro Portability: 219294334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 219398121Sgshapiro available. 219494334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 219594334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 219694334Sgshapiro settings. Patch from Elias Halldor Agustsson of 219794334Sgshapiro Skyrr. 219894334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 219994334Sgshapiro noted by John Beck. 220094334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 220194334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 220294334Sgshapiro Rajesh Somasund of Hewlett-Packard. 220394334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 220494334Sgshapiro SMTP AUTH information. This feature was actually added in 220594334Sgshapiro 8.12.0 but a release note was not included. 220694334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 220794334Sgshapiro parameter is set and the LDAP lookup returns a temporary 220894334Sgshapiro error. 220994334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 221094334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 221194334Sgshapiro Krzysztof Oledzki. 221294334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 221394334Sgshapiro initialization as aliases are not needed for the MSP. 221494334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 221594334Sgshapiro is in use. Patch from Andrzej Filip. 221694334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 221794334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 221894334Sgshapiro This will only have an effect if a parameter is specified, 221994334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 222094334Sgshapiro it is embedded in square brackets. Problem noted by 222194334Sgshapiro Theo Van Dinter of Collective Technologies. 222294334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 222394334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 222494334Sgshapiro to allow for the proper time zone on systems where the 222594334Sgshapiro default results in misleading time stamps. That is, syslog 222694334Sgshapiro time stamps and Date headers on submitted mail will use the 222794334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 222894334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 222994334Sgshapiro by Neil Rickert of Northern Illinois University. 223094334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 223194334Sgshapiro binary.

Colburn of the New Mexico 228290792Sgshapiro Institute of Mining and Technology. 228390792Sgshapiro Only log milter body replacements once instead of for each body 228490792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 228590792Sgshapiro the Finnish Meteorological Institute. 228690792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 228790792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 228890792Sgshapiro of the Finnish Meteorological Institute. 228990792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 229090792Sgshapiro needs to collect children status to avoid zombie processes. 229190792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 229290792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 229390792Sgshapiro commands are issued. This makes it consistent with normal 229490792Sgshapiro SMTP connections. 229590792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 229690792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 229790792Sgshapiro and Technology. 229890792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 229990792Sgshapiro message sender if the sender had used a deprecated RFC822 230090792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 230190792Sgshapiro Meteorological Institute. 230290792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 230390792Sgshapiro parsing.

Add configuration options for 242790792Sgshapiro different set*gid() calls to reset saved gid. Problem 242890792Sgshapiro found by Michal Zalewski. 242990792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 243090792Sgshapiro privileges by disabling debugging (command line -d flag) 243190792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 243290792Sgshapiro used. Suggested by Michal Zalewski. 243390792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 243490792Sgshapiro Problem found by Michal Zalewski. 243590792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 243690792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 243790792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 243890792Sgshapiro If debugging is turned on (-d0.10) print not just the default 243990792Sgshapiro values for configuration file and pid file but also the 244090792Sgshapiro selected values. Problem noted by Brad Chapman. 244190792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 244290792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 244390792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 244490792Sgshapiro this only applied to hostname canonification. Problem 244590792Sgshapiro noted by Bill Fenner of AT&T Research. 244690792Sgshapiro Ignore comments in NIS host records when trying to find the 244790792Sgshapiro canonical name for a host. 244890792Sgshapiro When sendmail has extra privileges, limit mail submission command 244990792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 245090792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 245190792Sgshapiro suggestion from Michal Zalewski. 245290792Sgshapiro Portability: 245390792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 245490792Sgshapiro `uname` does not given complete information. 245590792Sgshapiro Problem noted by Keith Neufeld of the Cessna 245690792Sgshapiro Aircraft Company. 245790792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 245890792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 245990792Sgshapiro Avoid compiler warnings by not using pointers to pass 246090792Sgshapiro integers.

You need to create a new user and 249390792Sgshapiro a new group before installing sendmail (both called smmsp by 249490792Sgshapiro default). The installation process tries to install 249590792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 249690792Sgshapiro default.

Suggested 250790792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 250890792Sgshapiro (IdS). 250990792Sgshapiro Fixed problem of a global variable being used for a timeout jump 251090792Sgshapiro point where the variable could become overused for more than 251190792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 251290792Sgshapiro a corrupted stack causing a core dump. The timeout is now 251390792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 251490792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 251590792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 251690792Sgshapiro checks (group ID of RunAsUser). This allows use of a 251790792Sgshapiro set-group-ID sendmail binary for initial message submission 251890792Sgshapiro and no set-user-ID root sendmail is needed. For details 251990792Sgshapiro see sendmail/SECURITY. 252090792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 252190792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 252290792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 252390792Sgshapiro with a fallback of sendmail.cf as configuration file. See 252490792Sgshapiro sendmail/SECURITY. 252590792Sgshapiro New configuration file option UseMSP to allow group writable queue 252690792Sgshapiro files if the group is the same as that of a set-group-ID 252790792Sgshapiro sendmail binary. See sendmail/SECURITY. 252890792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 252990792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 253090792Sgshapiro is sendmail.cf (to be backward compatible). This selection 253190792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 253290792Sgshapiro file: client or mta). See sendmail/SECURITY. 253390792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 253490792Sgshapiro command has been removed. 253590792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 253690792Sgshapiro at compile time or per host (ruleset). 253790792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 253890792Sgshapiro used to look up local mail recipients; the default value 253990792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 254090792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 254190792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 254290792Sgshapiro long, to accomodate envelope splitting. File systems with 254390792Sgshapiro a 14 character file name length limit are no longer 254490792Sgshapiro supported. 254590792Sgshapiro Recipient list used for delivery now gets internally ordered by 254690792Sgshapiro hostsignature (character string version of MX RR). This orders 254790792Sgshapiro recipients for the same MX RR's together meaning smaller 254890792Sgshapiro portions of the list need to be scanned (instead of the whole 254990792Sgshapiro list) each delivery() pass to determine piggybacking. The 255090792Sgshapiro significance of the change is better the larger the recipient 255190792Sgshapiro list. Hostsignature is now created during recipient list 255290792Sgshapiro creation rather than just before delivery. 255390792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 255490792Sgshapiro piggybacking (called coincidental) extended to coattail 255590792Sgshapiro piggybacking. Rather than complete MX RR matching 255690792Sgshapiro (coincidental) piggybacking is done if just the lowest value 255790792Sgshapiro preference matches (coattail). 255890792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 255990792Sgshapiro try other MX hosts if available. 256090792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 256190792Sgshapiro outgoing (client-side) SMTP Authentication. 256290792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 256390792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 256490792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 256590792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 256690792Sgshapiro A new ruleset authinfo can be used to return client side 256790792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 256890792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 256990792Sgshapiro removed in future versions. 257090792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 257190792Sgshapiro requires 334. Mercury 1.48 is a known offender. 257290792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 257390792Sgshapiro for the security layer in SMTP AUTH (SASL). See 257490792Sgshapiro doc/op/op.me for details. 257590792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 257690792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 257790792Sgshapiro signed the presented certificate, the CN and the MD5 hash 257890792Sgshapiro of the presented certificate, respectively. 257990792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 258090792Sgshapiro New ruleset srv_features to enable/disable certain features in the 258190792Sgshapiro server per connection. See doc/op/op.me for details. 258290792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 258390792Sgshapiro recipient; useful to decide whether a conection is secure 258490792Sgshapiro enough on a per recipient basis. 258590792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 258690792Sgshapiro for STARTTLS. 258790792Sgshapiro If no certificate has been requested, the macro {verify} has the 258890792Sgshapiro value "NOT". 258990792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 259090792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 259190792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 259290792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 259390792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 259490792Sgshapiro really required. This change results in a noticable 259590792Sgshapiro performance gains on most machines. Moreover, if shared 259690792Sgshapiro memory is in use, reuse the key several times. 259790792Sgshapiro Add queue groups which can be used to group queue directories with 259890792Sgshapiro the same behavior together. See doc/op/op.me for details. 259990792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 260090792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 260190792Sgshapiro are initially sorted which may result in faster envelope 260290792Sgshapiro splitting. If the mail is submitted directly from the 260390792Sgshapiro command line, then the value also limits the number of 260490792Sgshapiro processes to deliver the envelopes; if more envelopes are 260590792Sgshapiro created they are only queued up and must be taken care of 260690792Sgshapiro by a queue run. 260790792Sgshapiro The check for 'enough disk space' now pays attention to which file 260890792Sgshapiro system each queue directory resides in. 260990792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 261090792Sgshapiro New option QueueFileMode for the default permissions of queue files. 261190792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 261290792Sgshapiro group (one or more queues in a multi-queue environment 261390792Sgshapiro collected together) to process the same work list at the 261490792Sgshapiro same time. 261590792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 261690792Sgshapiro active queue runner processes. 261790792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 261890792Sgshapiro runners per queue group. 261990792Sgshapiro Queue member selection by substring pattern matching now allows 262090792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 262190792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 262290792Sgshapiro of the queue that match during processing. 262390792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 262490792Sgshapiro periodically forking a child to process the queue, a single 262590792Sgshapiro child is forked for each queue that sleeps between queue 262690792Sgshapiro runs. A SIGHUP signal can be sent to restart this 262790792Sgshapiro persistent queue runner. 262890792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 262990792Sgshapiro sendmail process which only runs the queue at an interval: 263090792Sgshapiro sendmail -q15m). 263190792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 263290792Sgshapiro Proposed by Thom O'Connor. 263390792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 263490792Sgshapiro unless the new -qf option or -v is used. 263590792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 263690792Sgshapiro several queue runners are started by hand to avoid contention. 263790792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 263890792Sgshapiro of the qf file (older entries first). 263990792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 264090792Sgshapiro a client to specify an amount of time within which an e-mail 264190792Sgshapiro should be delivered. New option DeliverByMin added to set the 264290792Sgshapiro minimum amount of time or disable the extension. 264390792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 264490792Sgshapiro not allowed unless escaped or quoted. 264590792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 264690792Sgshapiro by Leif Johansson of Stockholm University, which was based on 264790792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 264890792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 264990792Sgshapiro Technology, Stockholm, Sweden. 265090792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 265190792Sgshapiro behavior (no MX lookups), put the name in square brackets. 265290792Sgshapiro Proposed by Thom O'Connor. 265390792Sgshapiro Use shared memory to store free space of filesystems that are used 265490792Sgshapiro for queues, if shared memory is available and if a key is set 265590792Sgshapiro via SharedMemoryKey. This minimizes the number of system 265690792Sgshapiro calls to check the available space. See doc/op/op.me for 265790792Sgshapiro details. 265890792Sgshapiro If shared memory is compiled in the option -bP can be used to print 265990792Sgshapiro the number of entries in the queue(s). 266090792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 266190792Sgshapiro and the usual documentation for details. 266290792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 266390792Sgshapiro Remove '-U' (initial user submission) command line option as 266490792Sgshapiro announced in 8.10. 266590792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 266690792Sgshapiro New macro {addr_type} which contains whether the current address is 266790792Sgshapiro an envelope sender or recipient address. Suggested by 266890792Sgshapiro Neil Rickert of Northern Illinois University. 266990792Sgshapiro Two new options for host maps: -d (retransmission timeout), 267090792Sgshapiro -r (number of retries). 267190792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 267290792Sgshapiro separator such that a lookup can return both an attribute 267390792Sgshapiro and value separated by the given separator. 267490792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 267590792Sgshapiro to map class arith. 267690792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 267790792Sgshapiro (errors that occur when sending an error message) are dropped. 267890792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 267990792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 268090792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 268190792Sgshapiro requirements for files containing secret keys. This is 268290792Sgshapiro necessary for the MSP if client authentification is used. 268390792Sgshapiro Properly handle quoted filenames for class files (to allow for 268490792Sgshapiro filenames with spaces). 268590792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 268690792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 268790792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 268890792Sgshapiro {if_addr_out} address of interface of outgoing connection. 268990792Sgshapiro {if_family_out} family of interface of outgoing connection. 269090792Sgshapiro The latter two are only set if the interface does not belong 269190792Sgshapiro to the loopback net. 269290792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 269390792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 269490792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 269590792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 269690792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 269790792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 269890792Sgshapiro all connections for a single delivery attempt to succeed. 269990792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 270090792Sgshapiro a threshold number of recipients has been rejected (option 270190792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 270290792Sgshapiro Development Group. 270390792Sgshapiro New option DelayLA to delay connections if the load averages 270490792Sgshapiro exceeds the specified value. The default of 0 does not 270590792Sgshapiro change the previous behavior. A value greater than 0 270690792Sgshapiro will cause sendmail to sleep for one second on most 270790792Sgshapiro SMTP commands and before accepting connections if that 270890792Sgshapiro load average is exceeded. 270990792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 271090792Sgshapiro recipients that are sent during a connection to a mailer. 271190792Sgshapiro This also introduces a new mailer field 'r' which defines 271290792Sgshapiro the maximum number of recipients (defaults to 100). 271390792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 271490792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 271590792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 271690792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 271790792Sgshapiro instead. 271890792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 271990792Sgshapiro builtin mailer pathnames. Use TCP instead. 272090792Sgshapiro PH map code updated to use the new libphclient API instead of the 272190792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 272290792Sgshapiro University of Illinois at Urbana-Champaign. 272390792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 272490792Sgshapiro for direct (command line) submissions. 272590792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 272690792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 272790792Sgshapiro Hagino of the KAME Project. 272890792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 272990792Sgshapiro whose content is rewritten similar to Reply-To:. 273090792Sgshapiro Proposed by Andrzej Filip. 273190792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 273290792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 273390792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 273490792Sgshapiro AUTH/STARTTLS related logfile entries. 273590792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 273690792Sgshapiro before logging. 273790792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 273890792Sgshapiro (at LogLevel 9/10 or higher). 273990792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 274090792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 274190792Sgshapiro in which most commands are rejected due to check_relay or 274290792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 274390792Sgshapiro Change logging format for cloned envelopes to be similar to that for 274490792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 274590792Sgshapiro of the Universitat Regensburg. 274690792Sgshapiro Added libsm, a C library of general purpose abstractions including 274790792Sgshapiro assertions, tracing and debugging with named debug categories, 274890792Sgshapiro exception handling, malloc debugging, resource pools, 274990792Sgshapiro portability abstractions, and an extensible buffered I/O 275090792Sgshapiro package. It will at some point replace libsmutil. 275190792Sgshapiro See libsm/index.html for details. 275290792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 275390792Sgshapiro care of by fork() and exit(). 275490792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 275590792Sgshapiro more consistent portablity amongst different platforms 275690792Sgshapiro new and old (from new libsm). 275790792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 275890792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 275990792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 276090792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 276190792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 276290792Sgshapiro synchronizations calls. 276390792Sgshapiro Add per-recipient status information to mailq -v output. 276490792Sgshapiro T_ANY queries are no longer used by sendmail. 276590792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 276690792Sgshapiro too (see include/sm/cdefs.h for more info). 276790792Sgshapiro sendmail -d now has general support for named debug categories. 276890792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 276990792Sgshapiro for details. 277090792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 277190792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 277290792Sgshapiro generated by this condition were illegal (not RFC conform). 277390792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 277490792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 277590792Sgshapiro mailer and the recipient has hence been rejected during the 277690792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 277790792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 277890792Sgshapiro that do not have postmaster defined. If an email was sent 277990792Sgshapiro from an address to which a DSN cannot be returned and 278090792Sgshapiro in which at least one recipient address is non-deliverable, 278190792Sgshapiro then that email had been delivered in each queue run. 278290792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 278390792Sgshapiro degli Studi dell'Insubria. 278490792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 278590792Sgshapiro i.e., the corresponding code is always compiled in now. 278690792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 278790792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 278890792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 278990792Sgshapiro attempting to canonify a hostname, some broken nameservers 279090792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 279190792Sgshapiro lookups. If you want to excuse this behavior, use this new 279290792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 279390792Sgshapiro Mark Roth of the University of Illinois at 279490792Sgshapiro Urbana-Champaign. 279590792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 279690792Sgshapiro noted by Joy Latten of IBM. 279790792Sgshapiro ConnectionRateThrottle limits the number of connections per second 279890792Sgshapiro to each daemon individually, not the overall number of 279990792Sgshapiro connections. 280090792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 280190792Sgshapiro sendmail to use a default alias schema as outlined in the 280290792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 280390792Sgshapiro cf/README. 280490792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 280590792Sgshapiro the first character after the class name is not a '/' or a 280690792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 280790792Sgshapiro rest of the line will be parsed as a map lookup. This 280890792Sgshapiro allows classes to be filled via a map lookup. See op.me 280990792Sgshapiro for more syntax information. Specifically, this can be 281090792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 281190792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 281290792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 281390792Sgshapiro example). 281490792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 281590792Sgshapiro the default schema used in the above two items. 281690792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 281790792Sgshapiro warning if a program being run from a mailer or file class 281890792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 281990792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 282090792Sgshapiro if a program being run from a mailer or file class 282190792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 282290792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 282390792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 282490792Sgshapiro (without quotes) will disable this and return to the 282590792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 282690792Sgshapiro Suggested by Bryan Stansell of GNAC. 282790792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 282890792Sgshapiro HELO/EHLO commands. 282990792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 283090792Sgshapiro possible protocol family which may be used for outgoing 283190792Sgshapiro connections. Restrictions placed on one family only affect 283290792Sgshapiro outgoing connections on that particular family. Because of 283390792Sgshapiro this change, the ${client_flags} macro is not set until the 283490792Sgshapiro connection is established. Based on patch from Motonori 283590792Sgshapiro Nakamura of Kyoto University. 283690792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 283790792Sgshapiro when the -bv option is given by users who are neither root 283890792Sgshapiro nor the TrustedUser so users can not read private aliases, 283990792Sgshapiro forwards, or :include: files. It also will override the -v 284090792Sgshapiro (verbose) command line option. 284190792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 284290792Sgshapiro address can't be used for the outgoing connection, fall 284390792Sgshapiro back to the settings in ClientPortOptions (if set). 284490792Sgshapiro Problem noted by John Beck of Sun Microsystems. 284590792Sgshapiro New named config file rule check_data for DATA command (input: 284690792Sgshapiro number of recipients). Based on patch from Mark Roth of 284790792Sgshapiro the University of Illinois at Urbana-Champaign. 284890792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 284990792Sgshapiro can be specified using the '#' option character. For 285090792Sgshapiro example, 'ETRN #queuegroup'. 285190792Sgshapiro If an LDAP server times out or becomes unavailable, close the 285290792Sgshapiro current connection and reopen to get to one of the fallback 285390792Sgshapiro servers. Patch from Paul Hilchey of the University of 285490792Sgshapiro British Columbia. 285590792Sgshapiro Make default error number on $#error messages 550 instead of 501 285690792Sgshapiro because 501 is not allowed on all commands. 285790792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 285890792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 285990792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 286090792Sgshapiro if required. 286190792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 286290792Sgshapiro class instead. 286390792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 286490792Sgshapiro "IPv6:" tag to identify the address properly. For example, 286590792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 286690792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 286790792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 286890792Sgshapiro MTA is running. For example, during a queue run. 286990792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 287090792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 287190792Sgshapiro Nelson of IBM. 287290792Sgshapiro The maximum number of commands before the MTA slows down when too 287390792Sgshapiro many "light weight" commands have been received are now 287490792Sgshapiro configurable during compile time. The current values and 287590792Sgshapiro their defaults are: 287690792Sgshapiro MAXBADCOMMANDS 25 unknown commands 287790792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 287890792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 287990792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 288090792Sgshapiro MAXETRNCOMMANDS 8 ETRN 288190792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 288290792Sgshapiro Costales of SL3D, Inc. 288390792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 288490792Sgshapiro ${MyMacro} is defined but also that it is not empty. 288590792Sgshapiro Properly quote usernames with special characters if they are used 288690792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 288790792Sgshapiro Meteorological Institute. 288890792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 288990792Sgshapiro messages for messages for mailing list expanded addresses 289090792Sgshapiro which are not delivered on the initial attempt. 289190792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 289290792Sgshapiro the final dot has been sent to avoid affecting future 289390792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 289490792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 289590792Sgshapiro file systems that require to call fsync() for a directory 289690792Sgshapiro if the meta-data in it has been changed. This should be 289790792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 289890792Sgshapiro See sendmail/README for further information. 289990792Sgshapiro Avoid file locking deadlock when updating the statistics file if 290090792Sgshapiro sendmail is signaled to terminate. Problem noted by 290190792Sgshapiro Christophe Wolfhugel of France Telecom. 290290792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 290390792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 290490792Sgshapiro the Finnish Meteorological Institute. 290590792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 290690792Sgshapiro from Peter A. Friend of EarthLink. 290790792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 290890792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 290990792Sgshapiro flora.ca. 291090792Sgshapiro Portability: 291190792Sgshapiro Remove support for AIX 2, which supports only 14 character 291290792Sgshapiro filenames and is outdated anyway. Suggested by 291390792Sgshapiro Valdis Kletnieks of Virginia Tech. 291490792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 291590792Sgshapiro i.e., use default /usr/sbin, change owner/group 291690792Sgshapiro of man pages and user-executable to root/sys, set 291790792Sgshapiro optimization limit to 0 (unlimited). Based on patch 291890792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 291990792Sgshapiro Hurtta of the Finnish Meteorological Institute. 292090792Sgshapiro Do not assume LDAP support is installed by default under 292190792Sgshapiro Solaris 8 and later. 292290792Sgshapiro Add support for OpenUNIX. 292390792Sgshapiro CONFIG: Increment version number of config file to 10. 292490792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 292590792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 292690792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 292790792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 292890792Sgshapiro temporary lookup failures. 292990792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 293090792Sgshapiro action to be taken by aborting the search for domain names 293190792Sgshapiro or IP nets. 293290792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 293390792Sgshapiro relay address as long as the other part allows the email 293490792Sgshapiro to get through. 293590792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 293690792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 293790792Sgshapiro entry like user+*@domain. This allows handling of details by 293890792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 293990792Sgshapiro introduced to match only non-empty details of addresses. 294090792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 294190792Sgshapiro and hence there is no required order within the MAILER 294290792Sgshapiro section anymore except for MAILER(`uucp') which must come 294390792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 294490792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 294590792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 294690792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 294790792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 294890792Sgshapiro in the access map which returns OK or RELAY actually 294990792Sgshapiro terminates check_* ruleset checking. 295090792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 295190792Sgshapiro tls_rcpt, see cf/README for details. 295290792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 295390792Sgshapiro STARTTLS has been used to "(version=${tls_version} 295490792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 295590792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 295690792Sgshapiro options friends/haters instead of "To:" and enable 295790792Sgshapiro specification of whole domains instead of just users. 295890792Sgshapiro Notice: this change is not backward compatible. 295990792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 296090792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 296190792Sgshapiro cf/README for details. 296290792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 296390792Sgshapiro the access map. Proposed by Randall Winchester of the 296490792Sgshapiro University of Maryland. 296590792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 296690792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 296790792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 296890792Sgshapiro messages for an unauthorized relaying attempt/for access 296990792Sgshapiro map entries with RHS REJECT, respectively. 297090792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 297190792Sgshapiro to specify another domain to be added instead of the local one. 297290792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 297390792Sgshapiro Solving. 297490792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 297590792Sgshapiro options, see doc/op/op.me for details. 297690792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 297790792Sgshapiro the security layer in SMTP AUTH (SASL). 297890792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 297990792Sgshapiro immediately. 298090792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 298190792Sgshapiro allows checking of the return values of the DNS lookups. 298290792Sgshapiro See cf/README for details. 298390792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 298490792Sgshapiro temporary lookup failures. 298590792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 298690792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 298790792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 298890792Sgshapiro memory use. 298990792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 299090792Sgshapiro of the sender and the recipient address delimited by the 299190792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 299290792Sgshapiro in the access map. Based on code contributed by Mathias 299390792Sgshapiro Koerber of Singapore Telecommunications Ltd. 299490792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 299590792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 299690792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 299790792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 299890792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 299990792Sgshapiro the recipient host if LUSER_RELAY is used. 300090792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 300190792Sgshapiro +detail portion of the address when passing address to 300290792Sgshapiro local delivery agent. Disables alias and .forward +detail 300390792Sgshapiro stripping. Only use if LDA supports this. 300490792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 300590792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 300690792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 300790792Sgshapiro Routing lookups.

If sendmail needs to drop 365464562Sgshapiro these privileges and the operating system doesn't set the 365564562Sgshapiro saved-uid as well, exit with an error. Problem noted by 365664562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 365764562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 365864562Sgshapiro it populates. It is possible that some broken 365964562Sgshapiro implementations of snprintf() exist that do not do this. 366064562Sgshapiro Systems in this category should compile with 366164562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 366264562Sgshapiro system and report broken implementations to 366364562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 366464562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 366564562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 366664562Sgshapiro Implementation influenced by the example programs of 366764562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 366864562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 366964562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 367064562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 3671285303Sgshapiro cf/README and doc/op/op.me. 367264562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 367364562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 367464562Sgshapiro ${server_name}, and ${server_addr}. These are documented 3675285303Sgshapiro in cf/README and doc/op/op.me. 367664562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 367764562Sgshapiro random data. 367864562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 367964562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 368064562Sgshapiro try to use STARTTLS despite the security problems. 368164562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 368264562Sgshapiro support encryption. Based on code contributed by Tim 368364562Sgshapiro Martin of CMU. 368464562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 368564562Sgshapiro strength factor. 368664562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 368764562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 368864562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 368964562Sgshapiro of CMU. 369064562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 369164562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 369264562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 369364562Sgshapiro Fix the default family selection for DaemonPortOptions. As 369464562Sgshapiro documented, unless a family is specified in a 369564562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 369664562Sgshapiro also the default if no DaemonPortOptions value is set. 369764562Sgshapiro Therefore, IPv6 users should configure additional sockets 369864562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 369964562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 370064562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 370164562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 370264562Sgshapiro the interface information for an outgoing connection. 370364562Sgshapiro Not doing so was creating a mismatch between the socket 370464562Sgshapiro family and address used in subsequent connections if the 370564562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 370664562Sgshapiro by John Beck of Sun Microsystems. 370764562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 370864562Sgshapiro family based on the IP address. ${if_family} is no longer 370964562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 371064562Sgshapiro of Sun Microsystems. 371164562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 371264562Sgshapiro macros for both the incoming interface address/family and 371364562Sgshapiro the outgoing interface address/family. In order for M=b 371464562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 371564562Sgshapiro the incoming information in the queue file for later 371664562Sgshapiro delivery attempts. 371764562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 371864562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 371964562Sgshapiro smoe.org. 372064562Sgshapiro Add more vigilance in checking for putc() errors on output streams 372164562Sgshapiro to protect from a bug in Solaris 2.6's putc().

Problem noted by Ari Heikkinen of Pohjois-Savo 374364562Sgshapiro Polytechnic. 374464562Sgshapiro Under the proper circumstances, failed connections would be recorded 374564562Sgshapiro as "Bad file number" instead of "Connection failed" in the 374664562Sgshapiro queue file and persistent host status. Problem noted by 374764562Sgshapiro Graeme Hewson of Oracle. 374864562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 374964562Sgshapiro within the hoststatus directory (e.g., lost+found). 375064562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 375164562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 375264562Sgshapiro sender.

Problem noted by Michal Zalewski of the 402564562Sgshapiro "Internet for Schools" project (IdS). 402664562Sgshapiro SECURITY: There is a potential for a denial of service attack if 402764562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 402864562Sgshapiro sendmail process while it is rebuilding the aliases file 402964562Sgshapiro (leaving it in an inconsistent state). This option and 403064562Sgshapiro its use is deprecated and will be removed from a future 403164562Sgshapiro version of sendmail. 403264562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 403364562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 403464562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 403564562Sgshapiro (IdS). 403664562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 403764562Sgshapiro a large number of files. See cf/README for more details. 403864562Sgshapiro The directory structure of the distribution has changed slightly 403964562Sgshapiro for easier code sharing among the programs. 404064562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 404164562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 404264562Sgshapiro which hold the client's authentication credentials, 404364562Sgshapiro the mechanism used for authentication, and the 404464562Sgshapiro authorization identity (i.e., the AUTH= parameter if 404564562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 404664562Sgshapiro On systems which use the Torek stdio library (all of the BSD 404764562Sgshapiro distributions), use memory-buffered files to reduce 404864562Sgshapiro file system overhead by not creating temporary files on 404964562Sgshapiro disk. Contributed by Exactis.com, Inc. 405064562Sgshapiro New option DataFileBufferSize to control the maximum size of a 405164562Sgshapiro memory-buffered data (df) file before a disk-based file is 405264562Sgshapiro used. Contributed by Exactis.com, Inc. 405364562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 405464562Sgshapiro memory-buffered transcript (xf) file before a disk-based 405564562Sgshapiro file is used. Contributed by Exactis.com, Inc. 405664562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 405764562Sgshapiro now listen on several different ports. Use: 405864562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 405964562Sgshapiro to run a Message Submission Agent (MSA); this is turned 406064562Sgshapiro on by default in m4-generated .cf files; it can be turned 406164562Sgshapiro off with FEATURE(`no_default_msa'). 406264562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 406364562Sgshapiro begin using RFC 2476 Message Submission for initial user 406464562Sgshapiro message submission. XUSR may disappear from a future release. 406564562Sgshapiro The new '-G' (relay (gateway) submission) command line option 406664562Sgshapiro indicates that the message being submitted from the command 406764562Sgshapiro line is for relaying, not initial submission. This means 406864562Sgshapiro the message will be rejected if the addresses are not fully 406964562Sgshapiro qualified and no canonicalization will be done. Future 407064562Sgshapiro releases may even reject improperly formed messages. 407164562Sgshapiro The '-U' (initial user submission) command line option is 407264562Sgshapiro deprecated and may be removed from a future release. 407364562Sgshapiro Mail user agents should begin using '-G' to indicate that 407464562Sgshapiro this is a relay submission (the inverse of -U). 407564562Sgshapiro The next release of sendmail will assume that any message submitted 407664562Sgshapiro from the command line is an initial user submission and act 407764562Sgshapiro accordingly. 407864562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 407964562Sgshapiro program or deliver to file as the owner of that file, the 408064562Sgshapiro address is marked as unsafe. This means if RunAsUser is 408164562Sgshapiro set, users won't be able to use programs or delivery to 408264562Sgshapiro files in their .forward files. Administrators can override 408364562Sgshapiro this by setting the DontBlameSendmail option to the new 408464562Sgshapiro setting NonRootSafeAddr. 408564562Sgshapiro Allow group or world writable directories if the sticky bit is set 408664562Sgshapiro on the directory and DontBlameSendmail is set to 408764562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 408864562Sgshapiro InCert Software. 408964562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 409064562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 409164562Sgshapiro set in the DontBlameSendmail option. Requested by many. 409264562Sgshapiro New Timeout.control option to limit the total time spent satisfying 409364562Sgshapiro a control socket request. 409464562Sgshapiro New Timeout.resolver options for controlling BIND resolver 409564562Sgshapiro settings: 409664562Sgshapiro Timeout.resolver.retrans 409764562Sgshapiro Sets the resolver's retransmission time interval (in 409864562Sgshapiro seconds).

Sets both Timeout.resolver.retry.first 411064562Sgshapiro and Timeout.resolver.retry.normal. 411164562Sgshapiro Timeout.resolver.retry.first 411264562Sgshapiro Sets the number of times to retransmit a resolver 411364562Sgshapiro query for the first attempt to deliver a message. 411464562Sgshapiro Timeout.resolver.retry.normal 411564562Sgshapiro Sets the number of times to retransmit a resolver 411664562Sgshapiro query for all resolver lookups except the first 411764562Sgshapiro delivery attempt. 411864562Sgshapiro Contributed by Exactis.com, Inc. 411964562Sgshapiro Support multiple queue directories. To use multiple queues, supply 412064562Sgshapiro a QueueDirectory option value ending with an asterisk. For 412164562Sgshapiro example, /var/spool/mqueue/q* will use all of the 412264562Sgshapiro directories or symbolic links to directories beginning with 412364562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 412464562Sgshapiro mind, the queue directory structure should not be changed 412564562Sgshapiro while sendmail is running. Queue runs create a separate 412664562Sgshapiro process for running each queue unless the verbose flag is 412764562Sgshapiro given on a non-daemon queue run. New items are randomly 412864562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 412964562Sgshapiro Support different directories for qf, df, and xf queue files; if 413064562Sgshapiro subdirectories or symbolic links to directories of those names 413164562Sgshapiro exist in the queue directories, they are used for the 413264562Sgshapiro corresponding queue files. Keep in mind, the queue 413364562Sgshapiro directory structure should not be changed while sendmail is 413464562Sgshapiro running. Proposed by Mathias Koerber of Singapore 413564562Sgshapiro Telecommunications Ltd. 413664562Sgshapiro New queue file naming system which uses a filename guaranteed to be 413764562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 413864562Sgshapiro without fancy file system locking. Queued items can be 413964562Sgshapiro moved between queues easily. Contributed by Exactis.com, 414064562Sgshapiro Inc. 414164562Sgshapiro Messages which are undeliverable due to temporary address failures 414264562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 414364562Sgshapiro set. Contributed by Exactis.com, Inc. 414464562Sgshapiro New command line option '-L tag' which sets the identifier used for 414564562Sgshapiro syslog. Contributed by Exactis.com, Inc. 414664562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 414764562Sgshapiro avoids opening and reading each queue file when preparing 414864562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 414964562Sgshapiro Shared memory counters and microtimers functionality has been 415064562Sgshapiro donated by Exactis.com, Inc. 415164562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 415264562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 415364562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 415464562Sgshapiro being added. Suggested by Michael K. Sanders. 415564562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 415664562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 415764562Sgshapiro and John Beck of Sun Microsystems. 415864562Sgshapiro In low-disk space situations, where sendmail would previously refuse 415964562Sgshapiro connections, still accept them, but only allow ETRN commands. 416064562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 416164562Sgshapiro Ltd. 416264562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 416364562Sgshapiro on systems which support them. This can be used with LMTP 416464562Sgshapiro local delivery agents which listen on a named socket. An 416564562Sgshapiro example mailer might be: 416664562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 416764562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 416864562Sgshapiro A=FILE /var/run/lmtpd 416964562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 417064562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 417164562Sgshapiro instead. 417264562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 417364562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 417464562Sgshapiro connections), IPC (which will be deprecated in a future 417564562Sgshapiro version), and FILE (for UNIX domain socket delivery). 417664562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 417764562Sgshapiro flags. 417864562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 417964562Sgshapiro body of the original message on delivery status 418064562Sgshapiro notifications. 418164562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 418264562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 418364562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 418464562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 418564562Sgshapiro Steve Schweinhart of America Online. 418664562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 418764562Sgshapiro not be set after rulesets are defined. Suggested by 418864562Sgshapiro Mitchell Blank Jr of Exec-PC. 418964562Sgshapiro Do not report temporary failure on delivery to files.

Fix from Raj Kunjithapadam of 419964562Sgshapiro @Home Network. 420064562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 420164562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 420264562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 420364562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 420464562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 420564562Sgshapiro similar to check_rcpt etc. 420664562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 420764562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 420864562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 420964562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 421064562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 421164562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 421264562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 421364562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 421464562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 421564562Sgshapiro the corresponding DSN parameter values. Proposed by 421664562Sgshapiro Mathias Herberts. 421764562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 421864562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 421964562Sgshapiro before the message has been collected, thereafter it holds 422064562Sgshapiro the message size as computed by sendmail (and can be used 422164562Sgshapiro in check_compat). 422264562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 422364562Sgshapiro sendmail is using instead of the value of the DeliveryMode 422464562Sgshapiro option. 422564562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 422664562Sgshapiro Drop explicit From: if same as what would be generated only if it is 422764562Sgshapiro a local address.

Based on a 423964562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 424064562Sgshapiro Open maps only on demand, not at startup. 424164562Sgshapiro Log warning about unsupported IP address families. 424264562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 424364562Sgshapiro of the sum of all headers. This can be used to prevent 424464562Sgshapiro a denial-of-service attack. 424564562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 424664562Sgshapiro headers and parameters within those headers. This option 424764562Sgshapiro is intended to protect mail user agents from buffer 424864562Sgshapiro overflow attacks. 424964562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 425064562Sgshapiro alias recursion. 425164562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 425264562Sgshapiro Map type syslog to log the key via syslogd. 425364562Sgshapiro Entries in the alias file can be continued by putting a backslash 425464562Sgshapiro directly before the newline. 425564562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 425664562Sgshapiro dead.letter file, formerly hardcoded to 425764562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 425864562Sgshapiro default), sendmail will not attempt to save to a 425964562Sgshapiro system-wide dead.letter file if it can not bounce the mail 426064562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 426164562Sgshapiro file as it has in the past when the dead.letter file 426264562Sgshapiro could not be opened. 426364562Sgshapiro New option PidFile to define the location of the pid file. The 426464562Sgshapiro value of this option is macro expanded. 426564562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 426664562Sgshapiro process title shown in 'ps' listings. 426764562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 426864562Sgshapiro (along with the already existing macros): 426964562Sgshapiro ${daemon_info} Daemon information, e.g. 427064562Sgshapiro SMTP+queueing@00:30:00 427164562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 427264562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 427364562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 427464562Sgshapiro ${daemon_port} Daemon port, e.g., 25 427564562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 427664562Sgshapiro New macros especially for virtual hosting: 427764562Sgshapiro ${if_name} hostname of interface of incoming connection. 427864562Sgshapiro ${if_addr} address of interface of incoming connection. 427964562Sgshapiro The latter is only set if the interface does not belong to the 428064562Sgshapiro loopback net. 428164562Sgshapiro If a message being accepted via a method other than SMTP and 428264562Sgshapiro would be rejected by a header check, do not send the message. 428364562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 428464562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 428564562Sgshapiro Provide header value as quoted string in the macro 428664562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 428764562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 428864562Sgshapiro The length of the header value is stored in ${hdrlen}. 428964562Sgshapiro H*: allows to specify a default ruleset for header checks. This 429064562Sgshapiro ruleset will only be called if the individual header does 429164562Sgshapiro not have its own ruleset assigned. Suggested by Jan 429264562Sgshapiro Krueger of Unix-AG of University of Hannover. 429364562Sgshapiro The name of the header field stored in ${hdr_name}. 429464562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 429564562Sgshapiro removed if the config file version is greater than or equal 429664562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 429764562Sgshapiro input "token (1)" but does not match "token". 429864562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 429964562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 430064562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 430164562Sgshapiro Ericsson. 430264562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 430364562Sgshapiro messages with 8-bit text in headers. Problem noted by 430464562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 430564562Sgshapiro of Ericsson. 430664562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 430764562Sgshapiro modified database map file. Problem noted by Chris Adams 430864562Sgshapiro of Renaissance Internet Services. 430964562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 431064562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 431164562Sgshapiro queue up the message instead of bouncing it. 431264562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 431364562Sgshapiro standard does not provide any indication of what to do when 431464562Sgshapiro something other than 250 is received. Based on a patch 431564562Sgshapiro from Steve Schweinhart of America Online. 431664562Sgshapiro New option TrustedUser allows to specify a user who can own 431764562Sgshapiro important files instead of root. This requires HASFCHOWN. 431864562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 431964562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 432064562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 432164562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 432264562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 432364562Sgshapiro $? tests also whether the macro is non-null. 432464562Sgshapiro Print an error message if a mailer definition contains an invalid 432564562Sgshapiro equate name. 432664562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 432764562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 432864562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 432964562Sgshapiro mailer to return after sending all data to it. 433064562Sgshapiro Only free memory from the process list when adding a new process 433164562Sgshapiro into a previously filled slot. Previously, the memory was 433264562Sgshapiro freed at removal time. Since removal can happen in a 433364562Sgshapiro signal handler, this may leave the memory map in an 433464562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 433564562Sgshapiro David Cooley of Colby College. 433664562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 433764562Sgshapiro local users in the passwd file. The UserDB code has 433864562Sgshapiro already decided the message will be passed to another host 433964562Sgshapiro for processing. Fix from Tony Landells of Burdett 434064562Sgshapiro Buckeridge Young Limited. 434164562Sgshapiro Support LDAP authorization via either a file containing the 434264562Sgshapiro password or Kerberos V4 using the new map options 434364562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 434464562Sgshapiro distinguished_name is who to login as. The method can be 434564562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 434664562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 434764562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 434864562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 434964562Sgshapiro of Stanford University. 435064562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 435164562Sgshapiro deprecated and will be removed in a future version. 435264562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 435364562Sgshapiro and the map has the column delimiter set, it turns that 435464562Sgshapiro response into a delimiter separated string. The LDAP map 435564562Sgshapiro will traverse multiple entries as well. LDAP alias maps 435664562Sgshapiro automatically set the column delimiter to the comma. 435764562Sgshapiro Based on patch from Booker Bense of Stanford University and 435864562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 435964562Sgshapiro Support return of multiple values for a single LDAP lookup. The 436064562Sgshapiro values to be returned should be in a comma separated string. 436164562Sgshapiro For example, `-v "email,emailother"'. Patch from 436264562Sgshapiro Curtis W. Hillegas of Princeton University. 436364562Sgshapiro Allow the use of LDAP for alias maps. 436464562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 436564562Sgshapiro attributes found in the match will be returned. 436664562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 436764562Sgshapiro breaking up a single entry into multiple entries. This is 436864562Sgshapiro needed for LDAP alias file specifications to allow for 436964562Sgshapiro comma separated key and value strings. 437064562Sgshapiro Keep connections to LDAP server open instead of opening and closing 437164562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 437264562Sgshapiro connections such that multiple maps which use the same 437364562Sgshapiro host, port, bind DN, and authentication will only result in 437464562Sgshapiro a single connection to that host. 437564562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 437664562Sgshapiro Be more careful about checking for errors and freeing memory on 437764562Sgshapiro LDAP lookups. 437864562Sgshapiro Use asynchronous LDAP searches to save memory and network 437964562Sgshapiro resources. 438064562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 438164562Sgshapiro Increase portability to the Netscape LDAP libraries. 438264562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 438364562Sgshapiro replaced with the literal contents of the map lookup key -- 438464562Sgshapiro note that this means a lookup can be done using the LDAP 438564562Sgshapiro special characters. The new '%0' token can be used instead 438664562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 438764562Sgshapiro For example, if the LDAP map specification contains '-k 438864562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 438964562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 439064562Sgshapiro user attribute. Instead, if the LDAP map specification 439164562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 439264562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 439364562Sgshapiro with the name "*". 439464562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 439564562Sgshapiro more than one is returned, it is equivalent to no records 439664562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 439764562Sgshapiro alias dereference option; "-Z size" limits the number of 439864562Sgshapiro matches to return. 439964562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 440064562Sgshapiro LDAP maps. The value should only contain LDAP specific 440164562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 440264562Sgshapiro settings will be used for all LDAP maps unless they are 440364562Sgshapiro specified in the individual map specification ('K' 440464562Sgshapiro command). This option should be set before any LDAP maps 440564562Sgshapiro are defined. 440664562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 440764562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 440864562Sgshapiro Tech. 440964562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 441064562Sgshapiro particular, class entries get much smaller, which can be 441164562Sgshapiro important if you have large classes. 441264562Sgshapiro On network-related temporary failures, record the hostname which 441364562Sgshapiro gave error in the queued status message. Requested by 441464562Sgshapiro Ulrich Windl of the Universitat Regensburg. 441564562Sgshapiro Add new F=% mailer flag to allow for a store and forward 441664562Sgshapiro configuration. Mailers which have this flag will not attempt 441771345Sgshapiro delivery on initial receipt of a message or on queue runs 441864562Sgshapiro unless the queued message is selected using one of the 441964562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 442064562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 442164562Sgshapiro New option ControlSocketName which, when set, creates a daemon 442264562Sgshapiro control socket. This socket allows an external program to 442364562Sgshapiro control and query status from the running sendmail daemon 442464562Sgshapiro via a named socket, similar to the ctlinnd interface to the 442564562Sgshapiro INN news server. Access to this interface is controlled by 442664562Sgshapiro the UNIX file permissions on the named socket on most UNIX 442764562Sgshapiro systems (see sendmail/README for more information). An 442864562Sgshapiro example control program is provided as contrib/smcontrol.pl. 442964562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 443064562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 443164562Sgshapiro number of processors online on the system (if that can be 443264562Sgshapiro determined). For single processor machines, this change 443364562Sgshapiro has no effect. 443464562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 443564562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 443664562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 443764562Sgshapiro Motonori Nakamura of Kyoto University. 443864562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 443964562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 444064562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 444164562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 444264562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 444364562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 444464562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 444564562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 444664562Sgshapiro connection-based denial of service attacks. 444764562Sgshapiro Log basic information about authenticated connections at LogLevel 444864562Sgshapiro 10 or higher. 444964562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 445064562Sgshapiro information (from= syslog line). 445164562Sgshapiro Log the DSN code for each recipient if one is available as a new 445264562Sgshapiro equate (dsn=). 445364562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 4454120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 4455120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 4456120256Sgshapiro of the University of Illinois at Urbana-Champaign. 445764562Sgshapiro Detect temporary lookup failures in the host map if looking up a 445864562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 445964562Sgshapiro Finnish Meteorological Institute. 446064562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 446164562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 446264562Sgshapiro When a forward file points to an alias which runs a program, run 446364562Sgshapiro the program as the default user and the default group, not 446464562Sgshapiro the forward file user. This change also assures the 446564562Sgshapiro :include: directives in aliases are also processed using 446664562Sgshapiro the default user and group. Problem noted by Sergiu 446764562Sgshapiro Popovici of DNT Romania. 446864562Sgshapiro Prevent attempts to save a dead.letter file for a user with 446964562Sgshapiro no home directory (/no/such/directory). Problem noted by 447064562Sgshapiro Michael Brown of Finnigan FT/MS. 447164562Sgshapiro Include message delay and number of tries when logging that a 447264562Sgshapiro message has been completely delivered (LogLevel of 10 or 447364562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 447464562Sgshapiro Log the sender of a message even if none of the recipients were 447564562Sgshapiro accepted. If some of the recipients were rejected, it is 447664562Sgshapiro helpful to know the sender of the message. 447764562Sgshapiro Check the root directory (/) when checking a path for safety. 447864562Sgshapiro Problem noted by John Beck of Sun Microsystems. 447964562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 448064562Sgshapiro interactive and delivering to an alias which resolves to 448164562Sgshapiro multiple files. 448264562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 448364562Sgshapiro greater (see below); the help function doesn't print the 448464562Sgshapiro version of sendmail any longer, instead it is placed in 448564562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 448664562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 448764562Sgshapiro skipped and a version line (#vers) is introduced. The 448864562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 448964562Sgshapiro version is found, a warning is logged. The '#vers' 449064562Sgshapiro directive should be placed at the top of the help file. 449164562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 449264562Sgshapiro disk succeeded. Suggested by Nick Christenson. 449364562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 449464562Sgshapiro length before the attempt. 449564562Sgshapiro If a forward points to a filename for delivery, change to the 449664562Sgshapiro user's uid before checking permissions on the file. This 449764562Sgshapiro allows delivery to files on NFS mounted directories where 449864562Sgshapiro root is remapped to nobody. Problem noted by Harald 449964562Sgshapiro Daeubler of Universitaet Ulm. 450064562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 450164562Sgshapiro host status files, not all files. 450264562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 450364562Sgshapiro in the queue file for the message and set when delivery 450464562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 450564562Sgshapiro Wonderworks Inc. 450664562Sgshapiro Add support for storing information between rulesets using the new 450764562Sgshapiro macro map class. This can be used to store information 450864562Sgshapiro between queue runs as well using $={persistentMacros}. 450964562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 451064562Sgshapiro of Hannover. 451164562Sgshapiro New map class arith to allow for computations in rules. The 451264562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 451364562Sgshapiro as key. The two operands are specified as arguments; the 451464562Sgshapiro lookup returns the result of the computation. For example, 451564562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 451664562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 451764562Sgshapiro Add new syntax for header declarations which decide whether to 451864562Sgshapiro include the header based on a macro rather than a mailer 451964562Sgshapiro flag: 452064562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 452164562Sgshapiro This should be used along with $={persistentMacros}. 452264562Sgshapiro It can be used for adding headers to a message based on 452364562Sgshapiro the results of check_* and header check rulesets. 452464562Sgshapiro Allow new named config file rule check_eoh which is called after 452564562Sgshapiro all of the headers have been collected. The input to the 452664562Sgshapiro ruleset the number of headers and the size of all of the 452764562Sgshapiro headers in bytes separated by $|. This ruleset along with 452864562Sgshapiro the macro storage map can be used to correlate information 452964562Sgshapiro gathered between headers and to check for missing headers. 453064562Sgshapiro See cf/README or doc/op/op.ps for an example. 453164562Sgshapiro Change the default for the MeToo option to True to correspond 453264562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 453364562Sgshapiro option is deprecated and will be removed from a future 453464562Sgshapiro version. 453564562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 453664562Sgshapiro Change the sendmail binary default for SuperSafe to True. 453764562Sgshapiro Display ruleset names in debug and address test mode output 453864562Sgshapiro if referencing a named ruleset. 453964562Sgshapiro New mailer equate m= which will limit the number of messages 454064562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 454164562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 454264562Sgshapiro using it to sort. Now all the same domains are really run 454364562Sgshapiro through the queue together. If they have the same MX host, 454464562Sgshapiro then they will have a much better opportunity to use the 454564562Sgshapiro connection cache if available. This should be a reasonable 454664562Sgshapiro performance improvement. Patch from Randall Winchester of 454764562Sgshapiro the University of Maryland. 454864562Sgshapiro If a message is rejected by a header check ruleset, log who would 454964562Sgshapiro have received the message if it had not been rejected. 455064562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 455164562Sgshapiro queue immediately.

Problem noted by Per 472664562Sgshapiro Hedeland of Ericsson. 472764562Sgshapiro mailq displays unprintable characters in addresses as their octal 472864562Sgshapiro representation and a leading backslash. This avoids problems 472964562Sgshapiro with "unprintable" characters. Problem noted by Michal 473064562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 473164562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 473264562Sgshapiro one character past the limit. This would cause subsequent 473364562Sgshapiro hops to break the line again. The '!' is now placed in 473464562Sgshapiro the last column of the limit if the line needs to be broken. 473564562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 473664562Sgshapiro from Per Hedeland of Ericsson. 473764562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 473864562Sgshapiro resolver will fall back to TCP. However, some 473964562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 474064562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 474164562Sgshapiro don't fail on ANY queries. 474264562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 474364562Sgshapiro address, do not send an empty postmaster notification DSN 474464562Sgshapiro to the postmaster.

Prindeville of Enteka Enterprise Technology 496964562Sgshapiro Services. 497064562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 497164562Sgshapiro names. Problem noted by Randall Winchester of Swales 497264562Sgshapiro Aerospace. 497364562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 497464562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 497564562Sgshapiro University and Brian Candler. 497664562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 497764562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 497864562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 497964562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 498064562Sgshapiro Institute. 498164562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 498264562Sgshapiro i.e., to set, add, or delete flags. 498364562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 498464562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 498564562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 498664562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 498764562Sgshapiro after check_rcpt and allows for exceptions from the checks. 498864562Sgshapiro CONFIG: Map declarations have been moved into their associated 498964562Sgshapiro feature files to allow greater flexibility in use of 499064562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 499164562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 499264562Sgshapiro line string for the local mailer. Requested by Il Oh of 499364562Sgshapiro Willamette Industries, Inc. 499464562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 499564562Sgshapiro converted to <user@d> 499664562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 499764562Sgshapiro Sun's older, broken configuration files. 499864562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 499964562Sgshapiro normal configuration, allowing anti-spam checks to be 500064562Sgshapiro performed. 500164562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 500264562Sgshapiro ${client_name} can't be resolved just temporarily. 500364562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 500464562Sgshapiro Institute. 500564562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 500664562Sgshapiro be accessed by their numbers). 500764562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 500864562Sgshapiro which describes whether to disallow "!" in the local part 500964562Sgshapiro of an address. 501064562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 501164562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 501264562Sgshapiro set. If the ruleset returns a mailer, the appropriate 501364562Sgshapiro action is taken, otherwise the returned tokens are ignored. 501464562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 501564562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 501664562Sgshapiro The latter is kept around for backward compatibility. 501764562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 501864562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 501964562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 502064562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 502164562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 502264562Sgshapiro Institute. 502364562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 502464562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 502564562Sgshapiro arguments overriding the mailer program, arguments, and 502664562Sgshapiro mailer definition flags. This makes it possible to use 502764562Sgshapiro other programs such as maildrop for local delivery. 502864562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 502964562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 503064562Sgshapiro Patch from Richard A.

Problem noted by Ezequiel H. Panepucci of 504664562Sgshapiro Yale University. 504764562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 504864562Sgshapiro be used for building. 504964562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 505064562Sgshapiro used for a fresh build. 505164562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 505264562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 505364562Sgshapiro ranlib. 505464562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 505564562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 505664562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 505764562Sgshapiro building of the man pages when defined. Suggested by Bryan 505864562Sgshapiro Costales. 505964562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 506064562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 506164562Sgshapiro installation of the sendmail helpfile and statistics file 506264562Sgshapiro respectively. Suggested by Bryan Costales. 506364562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 506464562Sgshapiro of Siemens Business Services. 506564562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 506664562Sgshapiro stdio library. The new buffered file I/O depends on the 506764562Sgshapiro Torek stdio library. This option can be either portable or 506864562Sgshapiro torek. 506964562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 507064562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 507164562Sgshapiro They should contain the C source files for the object files 507264562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 507364562Sgshapiro will be passed to the 'make depend' stage of compilation. 507464562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 507564562Sgshapiro in the sendmail distribution. Each has the form 507664562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 507764562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 507864562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 507964562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 508064562Sgshapiro building the distribution, but documentation on the changes 508164562Sgshapiro are in devtools/README. 508264562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 508364562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 508464562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 508564562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 508664562Sgshapiro new variable which identifies the root of the source 508764562Sgshapiro directories for all of the programs in the distribution. 508864562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 508964562Sgshapiro time. They can both still be overridden by setting the m4 509064562Sgshapiro macro. 509164562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 509264562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 509364562Sgshapiro build configurations, and places objects in obj.prefix.*/. 509464562Sgshapiro Complains as 'Build -f file' does for existing object 509564562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 509664562Sgshapiro Corporation. 509764562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 509864562Sgshapiro manual pages in the directory tree specified by 509964562Sgshapiro confMANROOTMAN. 510064562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 510164562Sgshapiro preformatted pages from the distribution. The new variable 510264562Sgshapiro confCOPY specifies the copying program. 510364562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 510464562Sgshapiro question. Suggested by Terry Lambert of Whistle 510564562Sgshapiro Communications. 510664562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 510764562Sgshapiro of the installed statistics and help files, respectively. 510864562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 510964562Sgshapiro operating system identity. Problem noted by Erik 511064562Sgshapiro Wachtenheim of Dartmouth College. 511164562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 511264562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 511364562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 511464562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 511564562Sgshapiro how to strip binaries. These are used by the new 511664562Sgshapiro install-strip target. 511764562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 511864562Sgshapiro the others (if it exists). 511964562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 512064562Sgshapiro then the default ones. 512190792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 512264562Sgshapiro as local delivery agent without LMTP mode, use 512364562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 512464562Sgshapiro to set the S flag. 512564562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 512664562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 512764562Sgshapiro Northern Illinois University. 512864562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 512964562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 513064562Sgshapiro the Finnish Meteorological Institute. 513164562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 513264562Sgshapiro MAILLOCK when compiling. Also requires linking with 513364562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 513464562Sgshapiro University. 513564562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 513664562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 513764562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 513864562Sgshapiro University. 513964562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 514064562Sgshapiro structure to the beginning of the program. This ensures that 514164562Sgshapiro the getservbyname() is done before any seteuid to a possibly 514264562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 514364562Sgshapiro on a Solaris system, this avoids syslog messages such as, 514464562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 514564562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 514664562Sgshapiro University. 514764562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 514864562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 514964562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 515064562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 515164562Sgshapiro characters (in LMTP mode), mail.local split the incoming 515264562Sgshapiro line up into 2046-character output lines (excluding the 515364562Sgshapiro newline).

Sites 565138032Speter which need the ability to override security can use the 565238032Speter DontBlameSendmail option. See the README file for more 565338032Speter information. 565438032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 565538032Speter if maps or alias files are in world writable directories. 565638032Speter This fixes the change added to 8.8.6 to prevent links in these 565738032Speter world writable directories. 565838032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 565938032Speter it is in a world writable directory. 566038032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 566138032Speter tty it may be able to push bytes back to the senders input. 566238032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 567138032Speter reverts back to the old behavior of using uid 1 and gid 1. 567238032Speter This is a security problem for Linux which has chosen that 567338032Speter uid and gid for user bin instead of daemon. If DefaultUser 567438032Speter is set in the configuration file, that value overrides this 567538032Speter default. 567690792Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-ID binaries 567738032Speter interfered with setting an alternate group id for the 567838032Speter RunAsUser option.

After this number is reached, sendmail 572238032Speter starts returning "452 Too many recipients" to all RCPT 572338032Speter commands. This can be used to limit the number of recipients 572438032Speter per envelope (in particular, to discourage use of the server 572538032Speter for spamming). Note: a better approach is to restrict 572638032Speter relaying entirely. 572738032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 572838032Speter to ldapx map and added timeout for ldap_open call to 572938032Speter avoid hanging sendmail in the event of hung LDAP servers. 573038032Speter Patch from Booker Bense of Stanford University. 573138032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

In particular, if you 579338032Speter have lots of virtual interfaces, this option will speed up 579438032Speter startup.

A config line 581038032Speter of the form: 581138032Speter HHeader: $>Ruleset 581238032Speter causes the indicated Ruleset to be invoked on the Header 581338032Speter when read. This ruleset works like the check_* rulesets -- 581438032Speter that is, it can reject mail on the basis of the contents. 581538032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 581638032Speter from hiding their connection information in Received: 581738032Speter headers. 581838032Speter When SingleThreadDelivery is active, deliveries to locked hosts 581938032Speter are skipped.

Suggested by Alexander Litvin. 582238032Speter The [FILE] mailer type now delivers to the file specified in the 582338032Speter A= equate of the mailer definition instead of $u. It also 582438032Speter obeys all of the F= mailer flags such as the MIME 582538032Speter 7/8 bit conversion flags. This is useful for defining 582638032Speter a mailer which delivers to the same file regardless of the 582764562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 582838032Speter Do not assume the identity of a remote connection is root@localhost 582938032Speter if the remote connection closes the socket before the 583038032Speter remote identity can be queried. 583138032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 583238032Speter Some mailers, including procmail, require that the real 583338032Speter uid is left unchanged by sendmail. Problem noted by Per 583438032Speter Hedeland of Ericsson. 583538032Speter No longer is the src/obj*/Makefile selected from a large list -- it 583638032Speter is now generated using the information in BuildTools/OS/ -- 583738032Speter some of the details are determined dynamically via 583838032Speter BuildTools/bin/configure.sh. 583938032Speter The other programs in the sendmail distribution -- mail.local, 584038032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 584138032Speter the new Build method which creates an operating system 584238032Speter specific Makefile using the information in BuildTools. 584338032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 584438032Speter a failure on one message won't affect future messages to the 584538032Speter same host). This is necessary if the remote host sends 584638032Speter a 451 error if the domain of the sender does not resolve 584738032Speter as is common in anti-spam configurations. Problem noted 584838032Speter by Mitchell Blank Jr of Exec-PC. 584938032Speter New "discard" mailer for check_* rulesets and header checking 585038032Speter rulesets. If one of the above rulesets resolves to the 585138032Speter $#discard mailer, the commands will be accepted but the 585238032Speter message will be completely discarded after it is accepting. 585338032Speter This means that even if only one of the recipients 585438032Speter resolves to the $#discard mailer, none of the recipients 585538032Speter will receive the mail. Suggested by Brian Kantor. 585638032Speter All but the last cloned envelope of a split envelope were queued 585738032Speter instead of being delivered.

To obtain the 597238032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 597338032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 597438032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 597538032Speter the user to setup different .forward files for 597638032Speter user+detail addressing. 597738032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 597838032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 597938032Speter DontProbeInterfaces, and DontBlameSendmail options. 598038032Speter CONFIG: by default do not allow relaying (that is, accepting mail 598138032Speter from outside your domain and sending it to another host 598238032Speter outside your domain). 598338032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 598438032Speter any site to any site. 598538032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 598638032Speter domain as defined by the 'm' class ($=m) to relay. 598738032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 598838032Speter the MX records of the host portion of an incoming recipient. 598938032Speter CONFIG: new FEATURE(access_db) which turns on the access database 599077349Sgshapiro feature. This database gives you the ability to allow 599138032Speter or refuse to accept mail from specified domains for 599238032Speter administrative reasons. By default, names that are listed 599338032Speter as "OK" in the access db are domain names, not host names. 599438032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 599538032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 599638032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 599738032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 599838032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 599938032Speter of FEATURE(access_db) and class 'R' to lookup individual 600038032Speter host names only. 600138032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 600238032Speter using % addressing is used, e.g. user%site@othersite, 600338032Speter and othersite is in class 'R', the check_rcpt ruleset 600438032Speter will strip @othersite and recheck user@site for relaying. 600538032Speter This feature changes that behavior. It should not be 600638032Speter needed for most installations. 600738032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 600838032Speter domain portion of the mail sender is a local host. This 600938032Speter should only be used if absolutely necessary as it opens 601038032Speter a window for spammers. Patch from Randall S.

Problem noted by Kari Hurtta of the Finnish 617138032Speter Meteorological Institute. 617238032Speter If /usr/tmp/dead.letter already existed, sendmail could not 617338032Speter add additional bounces to it. Problem noted by Thomas J. 617438032Speter Arseneault of SRI International. 617538032Speter If an SMTP mailer used a non-standard port number for the outgoing 617638032Speter connection, it would be displayed incorrectly in verbose mode. 617738032Speter Problem noted by John Kennedy of Cal State University, Chico. 617838032Speter Log the ETRN parameter specified by the client before altering them 617938032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 618038032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 618138032Speter User unknown with bogus delay= values. Change them to log 618238032Speter the same as compliant addresses. Problem noted by Kari E. 618338032Speter Hurtta of the Finnish Meteorological Institute. 618438032Speter Ignore the debug resolver option unless using sendmail debug trace 618538032Speter option for resolver. Problem noted by Greg Nichols of Wind 618638032Speter River Systems. 618738032Speter If SingleThreadDelivery was enabled and the remote server returned a 618838032Speter protocol error on the DATA command, the connection would be 618938032Speter closed but the persistent host status file would not be 619038032Speter unlocked so other sendmail processes could not deliver to 619138032Speter that host. Problem noted by Peter Wemm of DIALix. 619238032Speter If queueing up a message due to an expensive mailer, don't increment 619338032Speter the number of delivery attempts or set the last delivery 619438032Speter attempt time so the message will be delivered on the next 619538032Speter queue run regardless of MinQueueAge. Problem noted by 619638032Speter Brian J. Coan of the Institute for Global Communications. 619738032Speter Authentication warnings of "Processed from queue _directory_" and 619838032Speter "Processed by _username_ with -C _filename_" would be logged 619938032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 620038032Speter of the Finnish Meteorological Institute. 620138032Speter Use a better heuristic for detecting GDBM. 620238032Speter Log null connections on dropped connections. Problem noted by 620338032Speter Jon Lewis of Florida Digital Turnpike. 620438032Speter If class dbm maps are rebuilt, sendmail will now detect this and 620538032Speter reopen the map. Previously, they could give stale 620638032Speter results during a single message processing (but would 620738032Speter recover when the next message was received). Fix from 620838032Speter Joe Pruett of Q7 Enterprises. 620938032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 621038032Speter requests. Problem noted by Kari E. Hurtta of the 621138032Speter Finnish Meteorological Institute. 621238032Speter Do not send a bounce message back to the sender regarding bad 621338032Speter recipients if the SMTP connection is dropped before the 621438032Speter message is accepted. Problem noted by Kari E. Hurtta of the 621538032Speter Finnish Meteorological Institute. 621638032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 621738032Speter sendmail via a UNIX pipe. This will allow rulesets using 621838032Speter $&{client_name} to process without sending the string through 621938032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 622038032Speter A combination of deferred delivery mode, a double bounce situation, 622138032Speter and the inability to save a bounce message to 622238032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 622338032Speter to postmaster but not remove the offending envelope from the 622438032Speter queue causing it to create a new bounce message each time the 622538032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 622638032Speter Associates. 622738032Speter Remove newlines from hostname information returned via DNS. There are 622838032Speter no known security implications of newlines in hostnames as 622938032Speter sendmail filters newlines in all vital areas; however, this 623038032Speter could cause confusing error messages. 623138032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 623238032Speter rejected if any of the specified addresses were bad. This 623338032Speter behavior was modified to only reject the bad addresses and not 623438032Speter the entire message. Problem noted by Jozsef Hollosi of 623538032Speter SuperNet, Inc. 623638032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 623738032Speter Bryan Costales of InfoBeat, Inc. 623838032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 623938032Speter mailers. Problem noted by Kari E. Hurtta of the 624038032Speter Finnish Meteorological Institute. 624138032Speter An error in calculating the available space in the list of addresses 624238032Speter for logging deliveries could cause an address to be silently 624338032Speter dropped. 624438032Speter Include the initial user environment if sendmail is restarted via 624538032Speter a HUP signal. This will give room for the process title. 624638032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 624738032Speter Mail could be delivered without a body if the machine does not 624838032Speter support flock locking and runs out of processes during 624938032Speter delivery. Fix from Chuck Lever of the University of Michigan. 625038032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 625138032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 625238032Speter Institute. 625338032Speter Make sure non-rebuildable database maps are opened before the 625464562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 625538032Speter are needed for verifying the left hand side of the aliases. 625638032Speter Problem noted by Lloyd Parkes of Victoria University. 625738032Speter Make sure sender RFC822 source route addresses are alias expanded for 625838032Speter bounce messages. Problem noted by Juergen Georgi of 625938032Speter RUS University of Stuttgart. 626038032Speter Minor lint fixes. 626138032Speter Return a temporary error instead of a permanent error if an LDAP map 626238032Speter search returns an error. This will allow sequenced maps which 626338032Speter use other LDAP servers to be checked. Fix from Booker Bense 626438032Speter of Stanford University. 626538032Speter When automatically converting from quoted printable to 8bit text do 626638032Speter not pad bare linefeeds with a space. Problem noted by Theo 626738032Speter Nolte of the University of Technology Aachen, Germany. 626838032Speter Portability: 626938032Speter Non-standard C compilers may have had a problem compiling 627038032Speter conf.c due to a standard C external declaration of 627138032Speter setproctitle(). Problem noted by Ted Roberts of 627238032Speter Electronic Data Systems. 627338032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 627438032Speter Jagielski of jaguNET Access Services. 627538032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 627638032Speter Digital UNIX: Digital UNIX (and possibly others) moves 627738032Speter loader environment variables into the loader memory 627838032Speter area. If one of these environment variables (such as 627938032Speter LD_LIBRARY_PATH) was the last environment variable, 628038032Speter an invalid memory address would be used by the process 628138032Speter title routine causing memory corruption. Problem 628238032Speter noted by Sam Hartman of Mesa Internet Systems. 628338032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 628438032Speter chownsafe() to always return 0 even if the OS does 628538032Speter not permit file giveaways. Problem noted by 628638032Speter Yasutaka Sumi of The University of Tokyo. 628764562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 628838032Speter Gerald Rinske of Siemens Business Services VAS. 628938032Speter Linux: Pad process title with NULLs. Problem noted by 629038032Speter Jon Lewis of Florida Digital Turnpike. 629138032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 629238032Speter incorrect value for the number of interfaces. 629338032Speter Problem noted by Chris Loelke of JetStream Internet 629438032Speter Services. 629538032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 629638032Speter Rinske of Siemens Business Services VAS. 629738032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 629838032Speter used on a Solaris machine. Problem noted by 629938032Speter Stephen Ma of Jtec Pty Limited. 630038032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 630138032Speter Services VAS. 630238032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 630338032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 630438032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 630538032Speter Ericsson. 630638032Speter 630764562Sgshapiro8.8.7/8.8.7 1997/08/03 630838032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 630938032Speter an exclusive lock already set -- i.e., almost all systems 631038032Speter except 4.4-BSD derived systems), the initial attempt at 631138032Speter rebuilding aliases file if the database didn't already 631238032Speter exist would fail. Patch from Raymund Will of LST Software 631338032Speter GmbH. 631438032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 631538032Speter Problem noted by Fredrik J�nsson of the Royal Institute 631638032Speter of Technology, Stockholm. 631738032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 631838032Speter some environments could give "multiple definitions" for these 631938032Speter routines during compilation. If using TCP Wrappers, assume 632038032Speter that these routines are included as though they were in the 632138032Speter C library. Patch from Robert La Ferla. 632238032Speter When a NEWDB database map was rebuilt at the same time it was being 632338032Speter used by a queue run, the maps could be left locked for the 632438032Speter duration of the queue run, causing other processes to hang. 632538032Speter Problem noted by Kendall Libby of Shore.NET. 632638032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 632738032Speter mail was passed on without any recipient header. This could 632838032Speter cause problems downstream. Problem noted by Xander Jansen 632938032Speter of SURFnet ExpertiseCentrum. 633038032Speter Give error when GDBM is used with sendmail. GDBM's locking and 633138032Speter linking of the .dir and .pag files interferes with sendmail's 633238032Speter locking and security checks. Problems noted by Fyodor 633338032Speter Yarochkin of the Kyrgyz Republic FreeNet. 633438032Speter Don't fsync qf files if SuperSafe option is not set. 633538032Speter Avoid extra calls to gethostbyname for addresses for which a 633638032Speter gethostbyaddr found no value. Also, ignore any returns 633738032Speter from gethostbyaddr that look like a dotted quad. 633838032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 633938032Speter "may be forged", since at the network level we pretty much 634038032Speter have to assume that the information is good. 634138032Speter In some cases, errors during an SMTP session could leave files 634238032Speter open or locked. 634338032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 634490792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 634538032Speter errors during testing. 634638032Speter Errors in file locking of NEWDB maps had the incorrect file name 634738032Speter printed in the error message. 634838032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 634938032Speter missing parameter were issued, the EHLO behaved like a HELO. 635038032Speter Load limiting never kicked in for incoming SMTP transactions if the 635143730Speter DeliveryMode=background and any recipient was an alias or 635238032Speter had a .forward file. From Nik Conwell of Boston University. 635338032Speter On some non-Posix systems, the decision of whether chown(2) permits 635438032Speter file giveaway was undefined. From Tetsu Ushijima of the 635538032Speter Tokyo Institute of Technology. 635638032Speter Fix race condition that could cause the body of a message to be 635738032Speter lost (so only the header was delivered). This only occurs 635838032Speter on systems that do not use flock(2), and only when a queue 635938032Speter runner runs during a critical section in another message 636038032Speter delivery. Based on a patch from Steve Schweinhart of 636138032Speter Results Computing. 636238032Speter If a qf file was found in a mail queue directory that had a problem 636338032Speter (wrong ownership, bad format, etc.) and the file name was 636438032Speter exactly MAXQFNAME bytes long, then instead of being tried 636538032Speter once, it would be tried on every queue run. Problem noted 636638032Speter by Bryan Costales of Mercury Mail. 636738032Speter If the system supports an st_gen field in the status structure, 636838032Speter include it when reporting that a file has changed after open. 636938032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 637038032Speter This out to be checked as well as reported, since it is 637138032Speter theoretically possible for an attacker to remove a file after 637238032Speter it is opened and replace it with another file that has the 637338032Speter same i-number, but some filesystems (notably AFS) return 637438032Speter garbage in this field, and hence always look like the file 637538032Speter has changed. As a practical matter this is not a security 637638032Speter problem, since the files can be neither hard nor soft links, 637738032Speter and on no filesystem (that I am aware of) is it possible to 637838032Speter have two files on the same filesystem with the same i-number 637938032Speter simultaneously. 638038032Speter Delete the root Makefile from the distribution -- it is only for 638138032Speter use internally, and does not work at customer sites. 638238032Speter Fix botch that caused the second MAIL FROM: command in a single 638338032Speter transaction to clear the entire transaction. Problem 638438032Speter noted by John Kennedy of Cal State University, Chico. 638538032Speter Work properly on machines that have _PATH_VARTMP defined without 638638032Speter a trailing slash. (And a pox on vendors that decide to 638738032Speter ignore the established conventions!) Problem noted by 638838032Speter Gregory Neil Shapiro of WPI. 638938032Speter Internal changes to make it easier to add another protocol family 639038032Speter (intended for IPv6). Patches are from John Kennedy of 639138032Speter CSU Chico. 639238032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 639338032Speter an extra space at the beginning of some lines. Problem 639438032Speter noted by Charles Karney of Princeton University; fix based 639538032Speter on a patch from Christophe Wolfhugel. 639638032Speter Portability: 639738032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 639838032Speter with the _Sendmail_ book, 2nd edition. Note that 639938032Speter the book is actually wrong: _PATH_SENDMAILCF should 640038032Speter be used instead. 640138032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 640238032Speter of Argonne National Laboratory. 640338032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 640438032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 640538032Speter SunOS: Include <memory.h> to fix warning from util.c. From 640638032Speter James Aldridge of EUnet Ltd. 640738032Speter Solaris: Change STDIR (location of status file) to /etc/mail 640838032Speter in Makefiles. 640938032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 641038032Speter Makefiles. Use NEWDB on Linux instead. 641138032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 641238032Speter exists but behaves differently than other OSes. 641338032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 641438032Speter around the problem. Problem noted by Tom Moore of 641538032Speter NCR Corp. 641638032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 641738032Speter noted by Tom Smith of Digital Equipment Corp. 641838032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 641938032Speter noted by Tom Good of the Community Access Information 642038032Speter Resource Network 642138032Speter SCO 4.2: compile problems caused by a change in the type of 642238032Speter the "length" parameters passed to accept, getpeername, 642338032Speter getsockname, and getsockopt. Adds new compile flags 642438032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. Problem reported 642538032Speter by Tom Good of St. Vincent's North Richmond Community 642638032Speter Mental Health Center Residential Services. 642738032Speter AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. 642838032Speter Suggested by Brett Hogden of Rochester Gas & Electric 642938032Speter Corp. 643038032Speter Linux: avoid compile problem for versions of <setjmp.h> that 643138032Speter #define both setjmp and longjmp.

This makes it possible to create a root 646938032Speter owned file in an arbitrary directory by inserting the symlink 647038032Speter into a writable directory after the initial lstat(2) check 647138032Speter determined that the file did not exist. The only verified 647238032Speter example of a system having these odd semantics for O_EXCL 647338032Speter and symbolic links was HP-UX prior to version 9.07. Most 647438032Speter systems do not have the problem, since a exclusive create 647538032Speter of a file disallows symbolic links. Systems that have been 647638032Speter verified to NOT have the problem include AIX 3.x, *BSD, 647738032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 647838032Speter and Ultrix. This is a potential exposure on systems that 647938032Speter have this bug and which do not have a MAILER-DAEMON alias 648038032Speter pointing at a legitimate account, since this will cause old 648138032Speter mail to be dropped in /var/tmp/dead.letter. 648238032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 648338032Speter if maps or alias files are in world writable directories. 648438032Speter If your system has alias maps in writable directories, it 648538032Speter is potentially possible for an attacker to replace the .db 648638032Speter (or .dir and .pag) files by symbolic links pointing at 648738032Speter another database; this can be used either to expose 648838032Speter information (e.g., by pointing an alias file at /etc/spwd.db 648938032Speter and probing for accounts), or as a denial-of-service attack 649038032Speter (by trashing the password database). The fix disallows 649138032Speter symbolic links entirely when rebuilding alias files or on 649238032Speter maps that are in writable directories, and always warns on 649338032Speter writable directories; 8.9 will probably consider writable 649438032Speter directories to be fatal errors. This does not represent an 649538032Speter exposure on systems that have alias files in unwritable 649638032Speter system directories. 649738032Speter SECURITY: disallow .forward or :include: files that are links (hard 649838032Speter or soft) if the parent directory (or any directory in the 649938032Speter path) is writable by anyone other than the owner. This is 650038032Speter similar to the previous case for user files. This change 650138032Speter should not affect most systems, but is necessary to prevent 650238032Speter an attacker who can write the directory from pointing such 650338032Speter files at other files that are readable only by the owner. 650438032Speter SECURITY: Tighten safechown rules: many systems will say that they 650538032Speter have a safe (restricted to root) chown even on files that 650638032Speter are mounted from another system that allows owners to give 650738032Speter away files. The new rules are very strict, trusting file 650838032Speter ownership only in those few cases where the system has 650938032Speter been verified to be at least as paranoid as necessary. 651038032Speter However, it is possible to relax the rules to partially 651138032Speter trust the ownership if the directory path is not world or 651238032Speter group writable. This might allow someone who has a legitimate 651338032Speter :include: file (referenced directly from /etc/aliases) to 651438032Speter become another non-root user if the :include: file is in a 651538032Speter non-writable directory on an NFS-mounted filesystem where 651638032Speter the local system says that giveaway is denied but it is 651738032Speter actually permitted. I believe this to be a very small set 651838032Speter of cases. If in doubt, do not point :include: aliases at 651938032Speter NFS-mounted filesystems. 652038032Speter SECURITY: When setting a numeric group id using the RunAsUser option 652138032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 652238032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 652338032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 652438032Speter The user id was still set properly. Problem noted by Uli 652538032Speter Pralle of the Technical University of Berlin. 652638032Speter Save the initial gid set for use when checking for if the 652738032Speter PrivacyOptions=restrictmailq option is set. Problem reported 652838032Speter by Wolfgang Ley of DFN-CERT. 652938032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 653038032Speter failure on one message won't affect future messages to the 653138032Speter same host). 653238032Speter IP source route printing had an "off by one" error that would 653338032Speter affect any options that came after the route option. Patch 653438032Speter from Theo de Raadt. 653538032Speter The "Message is too large" error didn't successfully bounce the error 653638032Speter back to the sender. Problem reported by Stephen More of 653738032Speter PSI; patch from Gregory Neil Shapiro of WPI. 653838032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 653938032Speter of 5.1.3); it apparently gets used in multiple ways. 654038032Speter Suggested by John Myers of Portola Communications. 654138032Speter Fix possible extra null byte generated during collection if errors 654238032Speter occur at the beginning of the stream. Patch contributed by 654338032Speter Andrey A. Chernov and Gregory Neil Shapiro. 654438032Speter Code changes to avoid possible reentrant call of malloc/free within 654538032Speter a signal handler. Problem noted by John Beck of Sun 654638032Speter Microsystems. 654738032Speter Move map initialization to be earlier so that check_relay ruleset 654838032Speter will have the latest version of the map data. Problem noted 654938032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 655038032Speter If there are fatal errors during the collection phase (e.g., message 655138032Speter too large) don't send the bogus message. 655238032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 655338032Speter have errors and have owner- aliases. Problem noted by Michael 655438032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 655538032Speter Avoid null pointer dereference on illegal Boundary= parameters in 655638032Speter multipart/mixed Content-Type: header. Problem noted by 655738032Speter Richard Muirden of RMIT University. 655838032Speter Always print error messages during newaliases (-bi) even if the 655938032Speter ErrorMode is not set to "print". Fix from Gregory Neil 656038032Speter Shapiro. 656138032Speter Test mode could core dump if you did a /map lookup in an optional map 656238032Speter that could not be opened. Based on a fix from John Beck of 656338032Speter Sun Microsystems. 656438032Speter If DNS is misconfigured so that the last MX record tried points to 656538032Speter a host that does not have an A record, but other MX records 656638032Speter pointed to something reasonable, don't bounce the message 656738032Speter with a "host unknown" error. Note that this should really 656838032Speter be fixed in the zone file for the domain. Problem noted by 656938032Speter Joe Rhett of Navigist, Inc. 657038032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 657138032Speter the message as having been tried; otherwise the next queue 657238032Speter run will not realize that this is a second attempt and will 657338032Speter retry immediately. Problem noted by Bryan Costales of 657438032Speter Mercury Mail. 657538032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 657638032Speter will be run until the later setting of the clock is reached. 657738032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 657838032Speter Morgan Stanley. 657938032Speter If the load average rises above the cutoff threshold (above which 658038032Speter sendmail will not process the queue at all) during a queue 658138032Speter run, abort the queue run immediately. Problem noted by 658238032Speter Bryan Costales of Mercury Mail. 658338032Speter The variable queue processing algorithm (based on the message size, 658438032Speter number of recipients, message precedence, and job age) was 658538032Speter non-functional -- either the entire queue was processed or 658638032Speter none of the queue was processed. The updated algorithm 658738032Speter does no queue run if a single recipient zero size job will 658838032Speter not be run. 658938032Speter If there is a fatal ("panic") message that will cause sendmail to 659038032Speter die immediately, never hold the error message for future 659138032Speter printing. 659238032Speter Force ErrorMode=print in -bt mode so that all errors are printed 659338032Speter regardless of the setting of the ErrorMode option in the 659438032Speter configuration file. Patch from Gregory Neil Shapiro. 659538032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 659638032Speter routine available in one of the libraries. Use it in conf.h. 659738032Speter The -m (match only) flag now works on host class maps. 659838032Speter If class hash or btree maps are rebuilt, sendmail will now detect 659938032Speter this and reopen the map. Previously, they could give 660038032Speter erroneous results during a single message processing 660138032Speter (but would recover when the next message was received). 660238032Speter Don't delete zero length queue files when doing queue runs until the 660338032Speter files are at least ten minutes old. This avoids a potential 660438032Speter race condition: the creator creates the qf file, getting back 660538032Speter a file descriptor. The queue runner locks it and deletes it 660638032Speter because it is zero length. The creator then writes the 660738032Speter descriptor that is now for a disconnected file, and the 660838032Speter job goes away. Based on a suggestion by Bryan Costales. 660938032Speter When determining the "validated" host name ($_ macro), do a forward 661038032Speter (A) DNS lookup on the result of the PTR lookup and compare 661138032Speter results. If they differ or if the PTR lookup fails, tag the 661238032Speter address as "may be forged". 661338032Speter Log null connections (i.e., hosts that connect but do not do any 661438032Speter substantive activity on the connection before disconnecting; 661538032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 661638032Speter Always permit "writes" to /dev/null regardless of the link count. 661738032Speter This is safe because /dev/null is special cased, and no open 661838032Speter or write is ever actually attempted. Patch from Villy Kruse 661938032Speter of TwinCom. 662038032Speter If a message cannot be sent because of a 552 (exceeded storage 662138032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 662238032Speter was given, don't return the body in the bounce, since there 662338032Speter is a very good chance that the message will double-bounce. 662438032Speter Fix possible line truncation if a quoted-printable had an =00 escape 662538032Speter in the body. Problem noted by Charles Karney of the Princeton 662638032Speter Plasma Physics Laboratory. 662738032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 662838032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 662938032Speter Institute. 663038032Speter The MaxDaemonChildren option wasn't applying to queue runs as 663138032Speter documented. Note that this increases the potential denial 663238032Speter of service problems with this option: an attacker can 663338032Speter connect many times, and thereby lock out queue runs as well 663438032Speter as incoming connections. If you use this option, you should 663538032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 663638032Speter to avoid this attack. Failure to limit noted by Matthew 663738032Speter Dillon of BEST Internet Communications. 663838032Speter Always give a message in newaliases if alias files cannot be 663938032Speter opened instead of failing silently. Suggested by Gregory 664038032Speter Neil Shapiro. This change makes the code match the O'Reilly 664138032Speter book (2nd edition). 664238032Speter Some older versions of the resolver could return with h_errno == -1 664338032Speter if no name server could be reached, causing mail to bounce 664438032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 664538032Speter John Beck of SunSoft. 664638032Speter If a :include: file is owned by a user that does not have an entry 664738032Speter in the passwd file, sendmail could dereference a null pointer. 664838032Speter Problem noted by Satish Mynam of Sun Microsystems. 664938032Speter Take precautions to make sure that the SMTP protocol cannot get out 665038032Speter of sync if (for example) an alias file cannot be opened. 665138032Speter Fix a possible race condition that can cause a SIGALRM to come in 665238032Speter immediately after a SIGHUP, causing the new sendmail to die. 665338032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 665438032Speter from Villy Kruse of TwinCom. 665538032Speter Ignore improperly formatted SMTP reply codes. Previously these were 665638032Speter partially processed, which could cause confusing error 665738032Speter returns. 665838032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 665938032Speter on some architectures. 666038032Speter Portability: 666138032Speter A/UX: from Jim Jagielski of NASA/GSFC. 666238032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 666338032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 666438032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 666538032Speter defined. Problem reported by A Sun of the University 666638032Speter of Washington. 666738032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 666838032Speter the system rather than guessing at compile time. 666938032Speter Patch contributed by John Beck of Sun Microsystems. 667038032Speter Intel Paragon: from Wendy Lin of Purdue University. 667138032Speter GNU Hurd: from Miles Bader of the GNU project. 667238032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 667338032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 667438032Speter Unfortunately releasing them opens a race condition, 667538032Speter but there appears to be no fix for this. Patch from 667638032Speter Gregory Neil Shapiro. 667738032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 667838032Speter Solaris: a bug in strcasecmp caused characters with the 667938032Speter high order bit set to apparently randomly match 668038032Speter letters -- for example, $| (0233) matches "i" and "I". 668138032Speter Problem noted by John Gregson of the University of 668238032Speter Cambridge. 668338032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 668438032Speter Kari Hurtta. 668538032Speter IRIX 6.x: Create Makefiles for systems that claim to be 668638032Speter IRIX64 but are 6.2 or higher (so use the regular 668738032Speter IRIX Makefile). 668838032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 668938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 669038032Speter CONFIG: Some canonification was still done for UUCP-like addresses 669138032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 669238032Speter Brian Candler. 669338032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 669438032Speter local names as local. Problem noted by Jeff Polk of BSDI; 669538032Speter fix provided by Gregory Neil Shapiro. 669638032Speter CONFIG: The "local:user" syntax entries in mailertables and other 669738032Speter "mailer:user" syntax locations returned an incorrect value 669838032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 669938032Speter CONFIG: Retain "+detail" information when forwarding mail to a 670038032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 670138032Speter Guenther of Gustavus Adolphus College. 670238032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 670338032Speter rules are the same as for aliasing. Based on a patch from 670438032Speter Gregory Neil Shapiro. 670538032Speter CONFIG: Break up parsing rules into several pieces; this should 670638032Speter have no functional change in this release, but makes it 670738032Speter possible to have better anti-spam rulesets in the future. 670838032Speter CONFIG: Disallow double dots in host names to avoid having the 670938032Speter HostStatusDirectory store status under the wrong name. 671038032Speter In some cases this can be used as a denial-of-service attack. 671138032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 671238032Speter Gregory Neil Shapiro. 671338032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 671438032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 671538032Speter don't include From_, and convert to 8-bit). Suggestions 671638032Speter from Kimmo Suominen and Roderick Schertler. 671764562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 671838032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 671938032Speter was specified, even when it wasn't. 672038032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 672138032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 672238032Speter "slip in" a symbolic link between the lstat(2) call and the 672338032Speter exclusive open. This is only a problem on System V derived 672438032Speter systems that allow an exclusive create on files that are 672538032Speter symbolic links pointing nowhere. 672638032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 672738032Speter not reset back to root, which on some systems would cause 672838032Speter later mailboxes to fail. Also, any partial message would 672938032Speter not be truncated, which could result in repeated deliveries. 673038032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 673138032Speter developers). 673238032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 673338032Speter change to the sendmail map code was made in 8.8.3. Problem 673438032Speter noted by Gregory Neil Shapiro. 673538032Speter MAKEMAP: Give warnings on file problems such as map files that are 673690792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 673738032Speter often run as root and hence has the potential for the same 673838032Speter sorts of problems as alias rebuilds. 673938032Speter MAKEMAP: Change compilation so that it will link properly on 674038032Speter NEXTSTEP. 674138032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 674238032Speter Accept an optional list of arguments following the server 674338032Speter name for the ETRN arguments to use (instead of $=w).

This 674738032Speter Perl script converts GECOS information in the /etc/passwd 674838032Speter file into aliases, allowing for faster access to full name 674938032Speter lookups; it is also clever about adding aliases (to root) 675038032Speter for system accounts. 675138032Speter NEW FILES: 675238032Speter src/safefile.c 675338032Speter cf/ostype/gnuhurd.m4 675438032Speter cf/ostype/irix6.m4 675538032Speter contrib/passwd-to-alias.pl 675638032Speter src/Makefiles/Makefile.IRIX64.6.1 675738032Speter src/Makefiles/Makefile.IRIX64.6.x 675838032Speter RENAMED FILES: 675938032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 676038032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 676138032Speter 676264562Sgshapiro8.8.5/8.8.5 1997/01/21 676338032Speter SECURITY: Clear out group list during startup. Without this, sendmail 676438032Speter will continue to run with the group permissions of the caller, 676538032Speter even if RunAsUser is specified. 676638032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 676738032Speter to any known attack, but it's best to be conservative. 676838032Speter Suggested by Peter Wemm of DIALix. 676938032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 677038032Speter security implications. Patch from Alex Garthwaite of the 677138032Speter University of Pennsylvania. 677238032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 677338032Speter would truncate the address after "Full". Although the -f 677438032Speter syntax is incorrect (since it is in the envelope, it 677538032Speter shouldn't have comments and full names), the failure mode 677638032Speter was unnecessarily awful. 677738032Speter Fix a possible null pointer dereference when converting 8-bit data 677838032Speter to a 7-bit format. Problem noted by Jim Hutchins of 677938032Speter Sandia National Labs and David James of British Telecom. 678038032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 678138032Speter runs. Although this really shouldn't be used (F=9 is for 678238032Speter final delivery only, and using it on an SMTP mailer makes 678338032Speter it possible for a message to be converted from 8->7->8->7 678438032Speter bits several times), it shouldn't have failed with a syserr. 678538032Speter Problem noted by Eric Hagberg of Morgan Stanley. 678638032Speter _Really_ fix the multiple :maildrop code in the user database 678738032Speter module. Patch from Roy Mongiovi of Georgia Tech. 678838032Speter Let F lines in the configuration file actually read root-only 678938032Speter files if the configuration file is safe. Based on a 679038032Speter patch from Keith Reynolds of SCO. 679138032Speter ETRN followed by QUIT would hold the connection open until the queue 679238032Speter run completed. Problem noted by Truck Lewis of TDK 679338032Speter Semiconductor Corp. 679438032Speter It turns out that despite the documentation, the TCP wrappers library 679538032Speter does _not_ log rejected connections. Do the logging ourselves. 679638032Speter Problem noted by Fletcher Mattox of the University of Texas 679738032Speter at Austin. 679838032Speter If sendmail finds a qf file in its queue directory that is an unknown 679938032Speter version (e.g., when backing out to an old version), the 680038032Speter error is reported on every queue run. Change it to only 680138032Speter give the error once (and rename the qf => Qf). Patch from 680238032Speter William A. Gianopoulos of Raytheon Company. 680338032Speter Start a new session when doing background delivery; currently it 680438032Speter ignored signals but didn't start a new signal, that caused 680538032Speter some problems if a background process tried to send mail 680638032Speter under certain circumstances. Problem noted by Eric Hagberg 680738032Speter of Morgan Stanley; fix from Kari Hurtta. 680838032Speter Simplify test for skipping a queue run to just check if the current 680938032Speter load average is >= the queueing load average. Previously 681038032Speter the check factored in some other parameters that caused it 681138032Speter to essentially never skip the queue run. Patch from Bryan 681238032Speter Costales. 681338032Speter If the SMTP server is running in "nullserver" mode (that is, it is 681438032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 681538032Speter (25) commands; this helps prevent a bad guy from putting 681638032Speter you into a tight loop as a denial-of-service attack. Based 681738032Speter on an e-mail conversation with Brad Knowles of AOL. 681838032Speter Slow down when too many "light weight" commands have been issued; 681938032Speter this helps prevent a class of denial-of-service attacks. 682038032Speter The current values and defaults are: 682138032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 682238032Speter MAXHELOCOMMANDS 3 HELO, EHLO 682338032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 682438032Speter MAXETRNCOMMANDS 8 ETRN 682538032Speter These will probably be configurable in a future release. 682638032Speter On systems that have uid_t typedefed to be an unsigned short, programs 682738032Speter that had the F=S flag and no U= equate would be invoked with 682838032Speter the real uid set to 65535 rather than being left unchanged. 682938032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 683038032Speter by Steve Hubert of the University of Washington, Seattle. 683138032Speter Mail that was Quoted-Printable encoded and had a soft line break on 683238032Speter the last line (i.e., an incomplete continuation) had the last 683338032Speter line dropped. Since this appears to be illegal it isn't 683438032Speter clear what to do with it, but flushing the last line seems 683538032Speter to be a better "fail soft" approach. Based on a patch from 683638032Speter Eric Hagberg. 683738032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 683838032Speter bogus HELO command still causes the "Polite people say HELO 683938032Speter first" error message. Problem pointed out by Chris Thomas 684038032Speter of UCLA; patch from John Beck of SunSoft. 684138032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 684271345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 684371345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 684471345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 684538032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 684638032Speter in a DATA transaction to be sticky; these can occur because 684738032Speter a message is too large, and smaller messages should still go 684838032Speter through. Problem noted by Matt Dillon of Best Internet 684938032Speter Communications. 685038032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 685138032Speter had been successfully delivered to the envelope sender. 685238032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 685338032Speter Gregory Neil Shapiro of WPI. 685438032Speter Give better diagnostics on long alias lines. Based on code contributed 685538032Speter by Patrick Gosling of the University of Cambridge. 685638032Speter Increase the number of virtual interfaces that will be probed for 685738032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 685838032Speter PORTABILITY: 685938032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 686038032Speter Toshiaki Nomura of Fujitsu Limited. 686138032Speter SunOS with LDAP support: compile problems with struct timeval. 686238032Speter Patch from Nick Cuccia of TCSI Corporation. 686338032Speter SCO: from Keith Reynolds of SCO. 686438032Speter Solaris: kstat load average computation wasn't being used. 686538032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 686638032Speter (Moscow). 686738032Speter OpenBSD: from Jason Downs of teeny.org. 686838032Speter Altos System V: from Tim Rice. 686938032Speter Solaris 2.5: from Alan Perry of SunSoft. 687038032Speter Solaris 2.6: from John Beck of SunSoft. 687138032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 687238032Speter of Pratt & Whitney <miorelli@pweh.com>. 687338032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 687438032Speter _just_right_ yet. Tweak it again. I'll omit the names 687538032Speter of the "contributors" (quantity two) in this one case. 687638032Speter As of now, NO MORE DISCUSSION about the syntax of the 687738032Speter Received: line. 687838032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 687938032Speter it never inserts that class into the output file. Fix it 688038032Speter so it will honor EXPOSED_USER but will _not_ include root 688138032Speter automatically in this class. Problem noted by Ronan KERYELL 688238032Speter of Centre de Recherche en Informatique de l'�cole Nationale 688338032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 688438032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 688538032Speter such as LUSER_RELAY. This change permits the following 688638032Speter syntaxes: ``local:'' will send to the same user on the 688738032Speter local machine (e.g., in a mailertable entry for "host", 688838032Speter ``local:'' will cause an address addressed to user@host to 688938032Speter go to user on the local machone). ``local:user'' will send 689038032Speter to the named user on the local machine. ``local:user@host'' 689138032Speter is equivalent to ``local:user'' (the host is ignored). In 689238032Speter all cases, the original user@host is passed in $@ (i.e., the 689338032Speter detail information). Inspired by a report from Michael Fuhr. 689438032Speter CONFIG: Strip quotes from the first word of an "error:" host 689538032Speter indication. This lets you set (for example) the LUSER_RELAY 689638032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 689738032Speter of the \" so that the resulting string is properly quoted. 689838032Speter Problem noted by Gregory Neil Shapiro of WPI. 689938032Speter OP.ME: documentation was inconsistent about whether sendmail did a 690038032Speter NOOP or a RSET to probe the connection (it does a RSET). 690138032Speter Inconsistency noted by Deeran Peethamparam. 690238032Speter OP.ME: insert additional blank pages so it will print properly on 690338032Speter a duplex printer. From Matthew Black of Cal State University, 690438032Speter Long Beach. 690538032Speter 690664562Sgshapiro8.8.4/8.8.4 1996/12/02 690738032Speter SECURITY: under some circumstances, an attacker could get additional 690838032Speter permissions by hard linking to files that were group 690938032Speter writable by the attacker. The solution is to disallow any 691038032Speter files that have hard links -- this will affect .forward, 691138032Speter :include:, and output files. Problem noted by Terry 691238032Speter Kyriacopoulos of Interlog Internet Services. As a 691338032Speter workaround, set UnsafeGroupWrites -- always a good idea. 691438032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 691538032Speter is, it is possible to do a denial-of-service attack on 691638032Speter MX hosts that rely on the use of the null MX list. There 691738032Speter is no danger if you have this option turned off (the default). 691838032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 691938032Speter unsafe. I know of no specific attack against this, although 692038032Speter a denial-of-service attack is probably possible, but in theory 692138032Speter you should not be able to safely tweak anything that affects 692238032Speter the permissions that are used when mail is delivered. 692338032Speter Purgestat could go into an infinite loop if one of the host status 692438032Speter directories somehow became empty. Problem noted by Roy 692538032Speter Mongiovi of Georgia Tech. 692638032Speter Processes got "lost" when counting children due to a race condition. 692738032Speter This caused "proc_list_probe: lost pid" messages to be logged. 692838032Speter Problem noted by several people. 692938032Speter On systems with System V SIGCLD child signal semantics (notably AIX 693038032Speter and HP-UX), mail transactions would print the message "451 693138032Speter SMTP-MAIL: lost child: No child processes". Problem noted 693238032Speter by several people. 693338032Speter Miscellaneous compiler warnings on picky compilers (or when setting 693438032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 693538032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 693638032Speter not be persistent between runs, since they are based on the 693738032Speter message rather than the host. Problem noted by Matt Dillon 693838032Speter of Best Internet Communications. 693938032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 694038032Speter of NCR (a.k.a., AT&T Global Information Solutions). 694138032Speter Avoid the possibility of having a child daemon run to completion 694238032Speter (including closing the SMTP socket) before the parent has 694338032Speter had a chance to close the socket; this can cause the parent 694438032Speter to hang for a long time waiting for the socket to drain. 694538032Speter Patch from Don Lewis of TDK Semiconductor. 694638032Speter If the fork() failed in a queue run, the queue runners would not be 694738032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 694838032Speter Some error conditions in ETRN could cause output without an SMTP 694938032Speter status code. Problem noted by Don Lewis. 695038032Speter Multiple :maildrop addresses in the user database didn't work properly. 695138032Speter Patch from Roy Mongiovi of Georgia Tech. 695238032Speter Add ".db" automatically onto any user database spec that does not 695338032Speter already have it; this is for consistency with makemap, the 695438032Speter K line, and the documentation. Inconsistency pointed out 695538032Speter by Roy Mongiovi. 695638032Speter Allow sendmail to be properly called in nohup mode. Patch from 695738032Speter Kyle Jones of UUNET. 695838032Speter Change ETRN to ignore but still update host status files; previously 695938032Speter it would ignore them and not save the updated status, which 696038032Speter caused stale information to be maintained. Based on a patch 696138032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 696238032Speter ETRN ignore the MinQueueAge option. 696338032Speter Patch long term host status to recover more gracefully from an empty 696438032Speter host status file condition. Patch from NAKAMURA Motonori 696538032Speter of Kyoto University. 696638032Speter Several patches to signal handling code to fix potential race 696738032Speter conditions from Don Lewis. 696838032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 696938032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 697038032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 697138032Speter compile flag; use NETINET instead. Solution based on a 697238032Speter patch from Bryan Costales. 697338032Speter PORTABILITY FIXES: 697438032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 697538032Speter /etc/security/passwd file when called as root. This 697638032Speter is very slow on some systems. To speed it up, use the 697738032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 697838032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 697938032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 698038032Speter Glicker of Burrelle's Information Service. 698138032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 698238032Speter from Makoto MATSUSHITA of Osaka University. 698338032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 698438032Speter Leeds University and SASABE Tetsuro of the University 698538032Speter of Tokyo. 698638032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 698738032Speter Services, Inc. 698838032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 698938032Speter I believe this to have only been a problem if you 699038032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 699138032Speter to stick with /etc/sendmail.cf as your One True Path. 699238032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 699338032Speter Martin Laubach of the Technischen Universit�t Wien. 699438032Speter CONFIG: change default Received: line to be multiple lines rather 699538032Speter than one long one. By popular demand. 699638032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 699738032Speter from Jerome Berkman of U.C. Berkeley. 699838032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 699938032Speter to take a very long time. Problem noted by Yoshiro YONEYA 700038032Speter of NTT Software Corporation. 700138032Speter CONTRIB: add etrn.pl, contributed by John Beck. 700238032Speter NEW FILES: 700338032Speter contrib/etrn.pl 700438032Speter 700564562Sgshapiro8.8.3/8.8.3 1996/11/17 700638032Speter SECURITY: it was possible to get a root shell by lying to sendmail 700738032Speter about argv[0] and then sending it a signal. Problem noted 700838032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 700938032Speter best-of-security list. 701038032Speter Log sendmail binary version number in "Warning: .cf version level 701138032Speter (%d) exceeds program functionality (%d) message" -- this 701238032Speter should make it clearer to people that they are running 701338032Speter the wrong binary. 701438032Speter Fix a problem that occurs when you open an SMTP connection and then 701538032Speter do one or more ETRN commands followed by a MAIL command; at 701638032Speter the end of the DATA phase sendmail would incorrectly report 701738032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 701838032Speter noted by Eric Bishop of Virginia Tech. 701938032Speter When doing text-based host canonification (typically /etc/hosts 702038032Speter lookup), a null host name would match any /etc/hosts entry 702138032Speter with space at the end of the line. Problem noted by Steve 702238032Speter Hubert of the University of Washington, Seattle. 702338032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 702438032Speter Problem reported by Tom Smith of Digital Equipment Corp. 702538032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 702638032Speter size PACKETSZ (512) is not sufficient for some nameserver 702738032Speter answers containing very many resource records. The resolver 702838032Speter may also switch to TCP and retry if it detects UDP packet 702938032Speter overflow. Also, allow for the fact that the resolver 703038032Speter routines res_query and res_search return the size of the 703138032Speter *un*truncated answer in case the supplied answer buffer it 703238032Speter not big enough to accommodate the entire answer. Patch from 703338032Speter Eric Wassenaar. 703438032Speter Improvements to MaxDaemonChildren code. If you think you have too 703538032Speter many children, probe the ones you have to verify that they 703638032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 703738032Speter Also, do this probe before growing the vector of children 703838032Speter pids; this previously caused the vector to grow indefinitely 703938032Speter due to a race condition. Problem reported by Kyle Jones of 704038032Speter UUNET. 704138032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 704238032Speter O_EXLOCK to zero; this fools the map compilation code into 704338032Speter thinking that it can avoid race conditions by locking on open. 704438032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 704538032Speter Leif Erlingsson of Data Lege. 704638032Speter Always call res_init() on startup (if compiled in, of course) to 704738032Speter allow the sendmail.cf file to tweak resolver flags; without 704838032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 704938032Speter Andrew Sun of Merrill Lynch. 705038032Speter Improvements to host status printing code. Suggested by Steve Hubert 705138032Speter of the University of Washington, Seattle. 705238032Speter Change MinQueueAge option processing to do the check for the job age 705338032Speter when reading the queue file, rather than at the end; this 705438032Speter avoids parsing the addresses, which can do DNS lookups. 705538032Speter Problem noted by John Beck of InReference, Inc. 705638032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 705738032Speter properly escaped. Problem noted by Peter Nilsson of the 705838032Speter University of Linkoping. 705938032Speter In some cases, sendmail would retain root permissions during queue 706038032Speter runs even if RunAsUser was set. Problem noted by Mark 706138032Speter Thomas of Mark G. Thomas Consulting. 706238032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 706338032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 706438032Speter the envelope, and the receiving SMTP server speaks DSN, then 706538032Speter the DSN would be both generated locally and propagated to the 706638032Speter other end. 706738032Speter The U= mailer field didn't correctly extract the group id if the 706838032Speter user id was numeric. Problem noted by Kenneth Herron of 706938032Speter MCI Telecommunications Communications. 707038032Speter If a message exceeded the fixed maximum size on input, the body of 707138032Speter the message was included in the bounce. Note that this did 707238032Speter not occur if it exceeded the maximum _output_ size. Problem 707338032Speter reported by Kyle Jones of UUNET. 707438032Speter PORTABILITY FIXES: 707538032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 707638032Speter AIX4 defines to use seteuid(2) instead, which 707738032Speter works on 4.1 as well as 4.2. Problem noted by 707838032Speter H�kan Lindholm of interAF, Sweden. 707938032Speter AIX4: use tzname[] vector to determine time zone name. 708038032Speter Patch from NAKAMURA Motonori of Kyoto University. 708138032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 708238032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 708338032Speter Solaris: kstat(3k) support for retrieving the load average. 708438032Speter This adds the LA_KSTAT definition for LA_TYPE. 708538032Speter The outline of the implementation was contributed 708638032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 708738032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 708838032Speter declaration of struct rusage at the top of conf.h; 708938032Speter change it to only be included if you are using gcc, 709038032Speter which is apparently the only compiler that requires 709138032Speter it in the first place. Problem noted by Jeff 709238032Speter Earickson of Colby College. 709338032Speter IRIX: don't default to using gcc. IRIX is a civilized 709438032Speter operating system that comes with a decent compiler 709538032Speter by default. Problem noted by Barry Bouwsma and 709638032Speter Kari Hurtta. 709738032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 709838032Speter consistency with other local mailers. Inconsistency 709938032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 710038032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 710138032Speter overhead) as part of the bestmx_is_local feature, the 710238032Speter domain part was dropped from the name. Patch from Steve 710338032Speter Hubert of the University of Washington, Seattle. 710438032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 710538032Speter end up being translated to the null host name, which would 710638032Speter return any entry in /etc/hosts that had a space at the end 710738032Speter of the line. Problem noted by Steve Hubert of the 710838032Speter University of Washington, Seattle. 710938032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 711038032Speter Polytechnic Institute. 711138032Speter MAKEMAP: tweak hash and btree parameters for better performance. 711238032Speter Patch from Matt Dillon of Best Internet Communications. 711338032Speter NEW FILES: 711438032Speter src/Makefiles/Makefile.Linux.ppc 711538032Speter cf/ostype/aix4.m4 711638032Speter cf/ostype/mklinux.m4 711738032Speter 711864562Sgshapiro8.8.2/8.8.2 1996/10/18 711938032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 712038032Speter changed the code but didn't fix the problem. 712138032Speter PORTABILITY FIXES: 712238032Speter Solaris: Don't use the system getusershell(3); it can 712338032Speter apparently corrupt the heap in some circumstances. 712438032Speter Problem found by Ken Pizzini of Spry, Inc. 712538032Speter OP.ME: document several mailer flags that were accidentally omitted 712638032Speter from this document.

Problem noted 713238032Speter by Dan Bernstein of the University of Illinois at Chicago. 713338032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 713438032Speter message could overflow a buffer if it was converted back 713538032Speter to 8 bits. This caused core dumps and has the potential 713638032Speter for a remote attack. Problem first noted by Gregory Shapiro 713738032Speter of WPI. 713838032Speter Avoid duplicate deliveries of error messages on systems that don't 713938032Speter have flock(2) support. Patch from Motonori Nakamura of 714038032Speter Kyoto University. 714138032Speter Ignore null FallBackMX (V) options. If this option is null (as 714238032Speter opposed to undefined) it can cause "null signature" syserrs 714338032Speter on illegal host names. 714438032Speter If a Base64 encoded text/plain message has no trailing newline in 714538032Speter the encoded text, conversion back to 8 bits will drop the 714638032Speter final line. Problem noted by Pierre David. 714738032Speter If running with a RunAsUser, sendmail would give bogus "cannot 714838032Speter setuid" (or seteuid, or setreuid) messages on some systems. 714938032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 715038032Speter Always print error messages in -bv mode -- previously, -bv would 715138032Speter be absolutely silent on errors if the error mode was sent 715238032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 715338032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 715438032Speter term host status. This is necessary because it is common 715538032Speter to do this when you know a host has just come back up. 715638032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 715738032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 715838032Speter University of Leicester. 715938032Speter If a service (such as NIS) is specified as the last entry in the 716038032Speter service switch, but that service is not compiled in, sendmail 716138032Speter would return a temporary failure when an entry was not found 716238032Speter in the map. This caused the message to be queued instead of 716338032Speter bouncing immediately. Problem noted by Harry Edmon of the 716438032Speter University of Washington. 716538032Speter PORTABILITY FIXES: 716638032Speter Solaris 2.3 had compilation problems in conf.c. Several 716738032Speter people pointed this out. 716838032Speter NetBSD from Charles Hannum of MIT. 716938032Speter AIX4 improvements based on info from Steve Bauer of South 717038032Speter Dakota School of Mines & Technology. 717138032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 717238032Speter Patch from Gil Kloepfer Jr. 717338032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 717438032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 717538032Speter were also in $=w. Problem noted by Zoltan Basti of 717638032Speter Softec. 717738032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 717838032Speter on a patch from Eric Hagberg of Morgan Stanley. 717938032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 718038032Speter of Stanford via Robert La Ferla. 718138032Speter 718264562Sgshapiro8.8.0/8.8.0 1996/09/26 718338032Speter Under some circumstances, Bcc: headers would not be properly 718438032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 718538032Speter Log a warning if the sendmail daemon is invoked without a full 718638032Speter pathname, which prevents "kill -1" from working. I was 718738032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 718838032Speter Fix small buffer overflow. Since the data in this buffer was not 718938032Speter read externally, there was no security problem (and in fact 719038032Speter probably wouldn't really overflow on most compilers). Pointed 719138032Speter out by KIZU takashi of Osaka University. 719238032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 719338032Speter if a FallbackMXHost was specified in the configuration file 719438032Speter -- all mail would be sent to the fallback even if the original 719538032Speter host was accessible. Pointed out by Munenari Hirayama of 719638032Speter NSC (Japan). 719738032Speter A message that didn't terminate with a newline would (sometimes) not 719838032Speter have the trailing "." added properly in the SMTP dialogue, 719938032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 720038032Speter The DaemonPortOptions suboption to bind to a particular address was 720138032Speter incorrect and nonfunctional due to a misunderstanding of the 720238032Speter semantics of binding on a passive socket. Patch from 720338032Speter NIIBE Yutaka of Mitsubishi Research Institute. 720438032Speter Increase the number of MX hosts for a single name to 100 to better 720538032Speter handle the truly huge service providers such as AOL, which 720638032Speter has 13 at the moment (and climbing). In order to avoid 720738032Speter trashing memory, the buffer for all names has only been 720838032Speter slightly increased in size, to 12.8K from 10.2K -- this means 720938032Speter that if a single name had 100 MX records, the average size 721038032Speter of those records could not exceed 128 bytes. Requested by 721138032Speter Brad Knowles of America On Line. 721238032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 721338032Speter Urged by Dan Bernstein of U.C. Berkeley. 721438032Speter Print q_statdate and q_specificity in address structure debugging 721538032Speter printout. 721638032Speter Expand MCI structure flag bits for debugging output. 721738032Speter Support IPv6-style domain literals, which can have colons between 721838032Speter square braces. 721938032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 722038032Speter this is an attempt to track down a bug that one person seems 722138032Speter to be having (it may be a Solaris bug!). 722238032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 722338032Speter this caused the NOTIFY info to sometimes be lost. Problem 722438032Speter pointed out by Claus Assmann of the 722538032Speter Christian-Albrechts-University of Kiel. 722638032Speter The statistics gathered in the sendmail.st file were too high; in 722738032Speter some cases failures (e.g., user unknown or temporary failure) 722838032Speter would count as a delivery as far as the statistics were 722938032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 723038032Speter Systems that don't have flock() would not send split envelopes in 723138032Speter the initial run. Problem pointed out by Leonard Zubkoff of 723238032Speter Dandelion Digital. 723338032Speter Move buffer overflow checking -- these primarily involve distrusting 723438032Speter results that may come from NIS and DNS. 723538032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 723638032Speter include <paths.h> and hence had the wrong pathnames for a few 723738032Speter things like /var/tmp. Reported by Matthew Green. 723838032Speter Conditions were reversed for the Priority: header, resulting in all 723938032Speter values being interpreted as non-urgent except for non-urgent, 724038032Speter which was interpreted as normal. Patch from Bryan Costales. 724138032Speter The -o (optional) flag was being ignored on hash and btree maps 724238032Speter since 8.7.2. Fix from Bryan Costales. 724338032Speter Content-Types listed in class "q" will always be encoded as 724438032Speter Quoted-Printable (or more accurately, will never be encoded 724538032Speter as base64). The class can have primary types (e.g., "text") 724638032Speter or full types (e.g., "text/plain"). Based on a suggestion by 724738032Speter Marius Olafsson of the University of Iceland. 724838032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 724938032Speter dialogue) so it can be passed to programs in mailers. 725038032Speter Define ${bodytype} to be the body type (from the -B flag or the 725138032Speter BODY= ESMTP parameter) so it can be passed to programs in 725238032Speter mailers. 725338032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 725438032Speter flag is set in the mailer descriptor. Suggested by John 725538032Speter Myers of CMU. 725638032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 725738032Speter The command takes a host name; data for that host is 725838032Speter immediately (and asynchronously) flushed. Because this shares 725938032Speter the -qR implementation, other hosts may be attempted, but 726038032Speter there should be no security implications. Implementation 726138032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 726238032Speter Add three new command line flags to pass in DSN parameters: -V envid 726338032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 726438032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 726538032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 726638032Speter that the -N flag applies to all recipients; there is no way 726738032Speter to specify per-address notifications on the command line, 726838032Speter nor is there an equivalent for the ORCPT= per-address 726938032Speter parameter. 727038032Speter Restore LogLevel option to be safe (it can only be increased); 727138032Speter apparently I went into paranoid mode between 8.6 and 8.7 727238032Speter and made it unsafe. Pointed out by Dabe Murphy of the 727338032Speter University of Maryland. 727438032Speter New logging on log level 15: all SMTP traffic. Patches from 727538032Speter Andrew Gross of San Diego Supercomputer Center. 727638032Speter NetInfo property value searching code wasn't stopping when it found 727738032Speter a match. This was causing the wrong values to be found (and 727838032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 727938032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 728038032Speter out by Bill Wisner of Electronics for Imaging that you can't 728138032Speter use the bracket address form for the MAIL_HUB macro, since 728238032Speter that causes the brackets to remain in the envelope recipient 728338032Speter address used for delivery. The simple fix (stripping off the 728438032Speter brackets in the config file) breaks the use of IP literal 728538032Speter addresses. This flag will solve that problem. 728638032Speter Add MustQuoteChars option. This is a list of characters that must 728738032Speter be quoted if they are found in the phrase part of an address 728838032Speter (that is, the full name part). The characters @,;:\()[] are 728938032Speter always in this list and cannot be removed. The default is 729038032Speter this list plus . and ' to match RFC 822. 729138032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 729238032Speter that do not include a host name for back compatibility with 729338032Speter some stupid SMTP clients. Setting this violates RFC 1123 729438032Speter section 5.2.5. 729538032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 729638032Speter rejecting connections if it has more than this many 729738032Speter outstanding children accepting mail. Note that you may 729838032Speter see more processes than this because of outgoing mail; this 729938032Speter is for incoming connections only. 730038032Speter Add ConnectionRateThrottle option. If set to a positive value, the 730138032Speter number of incoming SMTP connections that will be permitted 730238032Speter in a single second is limited to this number. Connections are 730338032Speter not refused during this time, just deferred. The intent is to 730438032Speter flatten out demand so that load average limiting can kick in. 730538032Speter It is less radical than MaxDaemonChildren, which will stop 730638032Speter accepting connections even if all the connections are idle 730738032Speter (e.g., due to connection caching). 730838032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 730938032Speter specifies how long cached information about the state of a 731038032Speter host will be kept before they are considered stale and the 731138032Speter host is retried. If you are using persistent host status 731238032Speter (i.e., the HostStatusDirectory option is set) this will apply 731338032Speter between runs; otherwise, it applies only within a single queue 731438032Speter run and hence is useful only for hosts that have large queues 731538032Speter that take a very long time to run. 731638032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 731738032Speter into being a single line even if they had newlines in them 731838032Speter when read. This is to get around a botch in Lotus Notes. 731938032Speter Text class maps were totally broken -- if you ever retrieved the last 732038032Speter item in a table it would be truncated. Problem noted by 732138032Speter Gregory Neil Shapiro of WPI. 732238032Speter Extend the lines printed by the mailq command (== the -bp flag) when 732338032Speter -v is given to 120 characters; this allows more information 732438032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 732538032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 732638032Speter this was treated as end-of-input. Problem noted by Bryan 732738032Speter Costales. 732838032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 732938032Speter to the queue file. Fix from John Hughes of Atlantic 733038032Speter Technologies, Inc. 733138032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 733238032Speter if this happens in a queue run it can cause nasty delays. 733338032Speter Problem noted by Mark Horton of AT&T. 733438032Speter If userdb entries pointed to userdb entries, and there were multiple 733538032Speter values for a given key, the database cursor would get 733638032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 733738032Speter of Georgia Tech. Fixed by reading all the values and creating 733838032Speter a comma-separated list; thus, the -v output will be somewhat 733938032Speter different for this case. 734038032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 734138032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 734238032Speter of Stanford University. 734338032Speter When envelopes were split due to aliases with owner- aliases, and 734438032Speter there was some error on one of the lists, more than one of 734538032Speter the owners would get the message. Problem pointed out by 734638032Speter Roy Mongiovi of Georgia Tech. 734738032Speter Detect excessive recursion in macro expansions, e.g., $X defined 734838032Speter in terms of $Y which is defined in terms of $X. Problem 734938032Speter noted by Bryan Costales; patch from Eric Wassenaar. 735038032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 735138032Speter some cases get trashed causing bogus From_ lines. Fix from 735238032Speter Kyle Jones of UUNET. 735338032Speter When doing load average initialization, if the nlist call for avenrun 735438032Speter failed, the second and subsequent lookups wouldn't notice 735538032Speter that fact causing bogus load averages to be returned. Noted 735638032Speter by Casper Dik of Sun Holland. 735738032Speter Fix problem with incompatibility with some versions of inet_aton that 735838032Speter have changed the return value to unsigned, so a check for an 735938032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 736038032Speter This could cause mail to addresses such as [foo.com] to bounce 736138032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 736238032Speter Pasteur Institute. 736338032Speter DSNs were inconsistent if a failure occurred during the DATA phase 736438032Speter rather than the RCPT phase: the Action: would be correct, but 736538032Speter the detailed status information would be wrong. Problem noted 736638032Speter by Bob Snyder of General Electric Company. 736738032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 736838032Speter that this is the initial MUA->MTA submission. The flag current 736938032Speter does nothing, but in future releases (when MUAs start using 737038032Speter these flags) it will probably turn on things like DNS 737138032Speter canonification. 737238032Speter Default end-of-line string (E= specification on mailer [M] lines) 737338032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 737438032Speter mailers. 737538032Speter Change the internal definition for the *file* and *include* mailers 737638032Speter to have $u in the argument vectors so that they aren't 737738032Speter misinterpreted as SMTP mailers and thus use \r\n line 737838032Speter termination. This will affect anyone who has redefined 737938032Speter either of these in their configuration file. 738038032Speter Don't assume that IDENT servers close the connection after a query; 738138032Speter responses can be newline terminated. From Terry Kennedy of 738238032Speter St. Peter's College. 738338032Speter Avoid core dumps on erroneous configuration files that have 738438032Speter $#mailer with nothing following. From Bryan Costales. 738538032Speter Avoid null pointer dereference with high debug values in unlockqueue. 738638032Speter Fix from Randy Martin of Clemson University. 738738032Speter Fix possible buffer overrun when expanding very large macros. Fix 738838032Speter from Kyle Jones of UUNET. 738938032Speter After 25 EXPN or VRFY commands, start pausing for a second before 739038032Speter processing each one. This avoids a certain form of denial 739138032Speter of service attack. Potential attack pointed out by Bryan 739238032Speter Costales. 739338032Speter Allow new named (not numbered!) config file rules to do validity 739438032Speter checking on SMTP arguments: check_mail for MAIL commands and 739538032Speter check_rcpt for RCPT commands. These rulesets can do anything 739638032Speter they want; their result is ignored unless they resolve to the 739738032Speter $#error mailer, in which case the indicated message is printed 739838032Speter and the command is rejected. Similarly, the check_compat 739938032Speter ruleset is called before delivery with "from_addr $| to_addr" 740038032Speter (the $| is a meta-symbol used to separate the two addresses); 740138032Speter it can give a "this sender can't send to this recipient" 740238032Speter notification. Note that this patch allows $| to stand alone 740338032Speter in rulesets. 740438032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 740538032Speter that have the name, IP address, and port number (respectively) 740638032Speter of the SMTP client (that is, the entity at the other end of 740738032Speter the connection. These can be used in (e.g.) check_rcpt to 740838032Speter verify that someone isn't trying to relay mail through your 740938032Speter host inappropriately. Be sure to use the deferred evaluation 741038032Speter form, for example $&{client_name}, to avoid having these bound 741138032Speter when sendmail reads the configuration file. 741238032Speter Add new config file rule check_relay to check the incoming connection 741338032Speter information. Like check_compat, it is passed the host name 741438032Speter and host address separated by $| and can reject connections 741538032Speter on that basis. 741638032Speter Allow IDA-style recursive function calls. Code contributed by Mark 741738032Speter Lovell and Paul Vixie. 741838032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 741938032Speter a virtual UUCP address using either a domain address or the $k 742038032Speter macro. Based on code contributed by Mark Lovell and Paul 742138032Speter Vixie. 742238032Speter Add Stanford LDAP map. Requires special libraries that are not 742338032Speter included with sendmail. Contributed by Booker C. Bense 742438032Speter <bbense@networking.stanford.edu>; contact him for support. 742538032Speter See also the src/READ_ME file. 742638032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 742738032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 742838032Speter only for debugging deep bits of code where it is important to 742938032Speter distinguish between the single-character metasymbol $+ and the 743038032Speter two characters $, +. 743138032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 743238032Speter debug_dumpstate. 743338032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 743438032Speter files that are group writable are considered "unsafe" -- that 743538032Speter is, programs and files referenced from such files are not 743638032Speter valid recipients. 743738032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 743838032Speter name that was not in DNS or was a domain-literal. Problem 743938032Speter noted by Tom May. 744038032Speter Change the introduction to error messages to more clearly delineate 744138032Speter permanent from temporary failures; if both existed in a 744238032Speter single message it could be confusing. Suggested by John 744338032Speter Beck of InReference, Inc. 744438032Speter The IngoreDot (i) option didn't work for lines that were terminated 744538032Speter with CRLF. Problem noted by Ted Stockwell of Secure 744638032Speter Computing Corporation. 744738032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 744838032Speter message headers. Problem reported by Matt Dillon of Best 744938032Speter Internet Communications. 745038032Speter Check for bogus characters in the 0200-0237 range; since these are 745138032Speter used internally, very strange errors can occur if those 745238032Speter characters appear in headers. Problem noted by Anders Gertz 745338032Speter of Lysator. 745438032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 745538032Speter recipient mailer has the F=9 flag set, and only works on 745638032Speter text/plain body types. Code contributed by Marius Olafsson 745738032Speter of the University of Iceland. 745838032Speter Special case "postmaster" name so that it is always treated as lower 745938032Speter case in alias files regardless of configuration settings; 746038032Speter this prevents some potential problems where "Postmaster" or 746138032Speter "POSTMASTER" might not match "postmaster". In most cases 746238032Speter this change is a no-op. 746338032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 746438032Speter Costales. 746538032Speter The -a map flag was ignored for dequote maps. Problem noted by 746638032Speter Bryan Costales. 746738032Speter Fix core dump when a lookup of a class "prog" map returns no 746838032Speter response. Patch from Bryan Costales. 746938032Speter Log instances where sendmail is deferring or rejecting connections 747038032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 747138032Speter Include port number in process title for network daemons. Suggested 747238032Speter by Kyle Jones of UUNET. 747338032Speter Send ``double bounces'' (errors that occur when sending an error 747438032Speter message) to the address indicated in the DoubleBounceAddress 747538032Speter option (default: postmaster). Previously they were always 747638032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 747738032Speter Add new mode, -bD, that acts like -bd in all respects except that 747838032Speter it runs in foreground. This is useful for using with a 747938032Speter wrapper that "watches" system services. Suggested by Kyle 748038032Speter Jones of UUNET. 748138032Speter Fix botch in spacing around (parenthesized) comments in addresses 748238032Speter when the comment comes before the address. Patch from 748338032Speter Motonori Nakamura of Kyoto University. 748438032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 748538032Speter that are being bounced to postmaster, rather than "Returned 748638032Speter mail". This permits the person who is postmaster more 748738032Speter easily determine what messages are to their role as 748838032Speter postmaster versus bounces to mail they actually sent. Based 748938032Speter on a suggestion by Motonori Nakamura. 749038032Speter Add new value "time" for QueueSortOrder option; this causes the queue 749138032Speter to be sorted strictly by the time of submission. Note that 749243730Speter this can cause very bad behavior over slow lines (because 749338032Speter large jobs will tend to delay small jobs) and on nodes with 749438032Speter heavy traffic (because old things in the queue for hosts that 749538032Speter are down delay processing of new jobs). Also, this does not 749638032Speter guarantee that jobs will be delivered in submission order 749738032Speter unless you also set DeliveryMode=queue. In general, it should 749838032Speter probably only be used on the command line, and only in 749938032Speter conjunction with -qRhost.domain. In fact, there are very few 750038032Speter cases where it should be used at all. Based on an 750138032Speter implementation by Motonori Nakamura. 750238032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 750338032Speter the same manner as other rulesets. Previously a temporary 750438032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 750538032Speter of Stanford University. 750638032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 750738032Speter 5yz (permanent failure) code. The next MX host will still be 750838032Speter tried if the connection cannot be opened in the first place 750938032Speter or if the MAIL command returns a 4yz (temporary failure) code. 751038032Speter (It's hard to know what to do here, since neither RFC 974 nor 751138032Speter RFC 1123 specify when to proceed to the next MX host.) 751238032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 751338032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 751438032Speter This causes map lookups that get a temporary failure (e.g., 751538032Speter name server failure) to _not_ defer the delivery of the 751638032Speter message. This should only be used if your configuration file 751738032Speter is prepared to do something sensible in this case. Based on 751838032Speter an idea by Gregory Shapiro of WPI. 751938032Speter Fix problem finding network interface addresses. Patch from 752038032Speter Motonori Nakamura. 752138032Speter Don't reject qf entries that are not owned by your effective uid if 752290792Sgshapiro you are not running set-user-ID; this makes management of 752380785Sgshapiro certain kinds of firewall setups difficult. Patch 752480785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 752538032Speter Add persistent host status. This keeps the information normally 752638032Speter maintained within a single queue run in disk files that are 752738032Speter shared between sendmail instances. The HostStatusDirectory 752838032Speter is the directory in which the information is maintained. If 752938032Speter not set, persistent host status is turned off. If not a full 753038032Speter pathname, it is relative to the queue directory. A common 753138032Speter value is ".hoststat". 753238032Speter There are also two new operation modes: 753338032Speter * -bh prints the status of hosts that have had recent 753438032Speter connections. 753538032Speter * -bH purges the host statuses. No attempt is made to save 753638032Speter recent status information. 753738032Speter This feature was originally written by Paul Vixie of Vixie 753838032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 753938032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 754038032Speter with my insistence that things fit cleanly into the V8 754138032Speter framework is gratefully appreciated. 754238032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 754338032Speter operate). Avoids letting two sendmails on the local machine 754464562Sgshapiro open connections to the same remote host at the same time. 754538032Speter This reduces load on the other machine, but can cause mail to 754638032Speter be delayed (for example, if one sendmail is delivering a huge 754738032Speter message, other sendmails won't be able to send even small 754838032Speter messages). Also, it requires another file descriptor (for the 754938032Speter lock file) per connection, so you may have to reduce 755038032Speter ConnectionCacheSize to avoid running out of per-process 755138032Speter file descriptors. Based on the persistent host status code 755238032Speter contributed by Paul Vixie and Mark Lovell. 755338032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 755438032Speter SafeFileEnvironment option is set. Problem noted by Bryan 755538032Speter Costales. 755638032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 755738032Speter file. Problem noted by Bryan Costales. 755838032Speter If a job was aborted using the interrupt signal (e.g., control-C from 755938032Speter the keyboard), on some occasions an empty df file would be 756038032Speter left around; these would collect in the queue directory. 756138032Speter Problem noted by Bryan Costales. 756238032Speter Change the makesendmail script to enhance the search for Makefiles 756338032Speter based on release number. For example, on SunOS 5.5.1, it will 756438032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 756538032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 756638032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 756738032Speter Webmasters. 756838032Speter When creating maps using "newaliases", always map the keys to lower 756938032Speter case when creating the map unless the -f flag is specified on 757038032Speter the map itself. Previously this was done based on the F=u 757138032Speter flag in the local mailer, which meant you could create aliases 757238032Speter that you could never access. Problem noted by Bob Wu of DEC. 757338032Speter When a job was read from the queue, the bits causing notification on 757438032Speter failure or delay were always set. This caused those 757538032Speter notifications to be sent even if NOTIFY=NEVER had been 757638032Speter specified. Problem noted by Steve Hubert of the University 757738032Speter of Washington, Seattle. 757838032Speter Add new configurable routine validate_connection (in conf.c). This 757938032Speter lets you decide if you are willing to accept traffic from 758038032Speter this host. If it returns FALSE, all SMTP commands will return 758138032Speter "550 Access denied". -DTCPWRAPPERS will include support for 758238032Speter TCP wrappers; you will need to add -lwrap to the link line. 758338032Speter (See src/READ_ME for details.) 758438032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 758538032Speter bounces. Some people seemed to think that this could be 758638032Speter confusing (even though it is true). Suggested by Motonori 758738032Speter Nakamura. 758838032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 758938032Speter user early in processing to avoid potential security problems. 759038032Speter However, this means that all .forward and :include: files must 759138032Speter be readable by that user, and all files to be written must be 759238032Speter writable by that user and all programs will be executed by that 759338032Speter user. It is also incompatible with the SafeFileEnvironment 759438032Speter option. In other words, it may not actually add much to 759538032Speter security. However, it should be useful on firewalls and other 759638032Speter places where users don't have accounts and the aliases file is 759738032Speter well constrained. 759838032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 759938032Speter only on the first attempt to delivery to an address. It could 760038032Speter be set to be lower than Timeout.connect on the principle that 760138032Speter the mail should go through quickly to responsive hosts; less 760238032Speter responsive hosts get to wait for the next queue run. 760338032Speter Fix a problem on Solaris that occasionally causes programs 760438032Speter (such as vacation) to hang with their standard input connected 760538032Speter to a UDP port. It also created some signal handling problems. 760638032Speter The problems turned out to be an interaction between vfork(2) 760738032Speter and some of the libraries, particularly NIS/NIS+. I am 760838032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 760938032Speter Change user class map to do the same matching that actual delivery 761038032Speter will do instead of just a /etc/passwd lookup. This adds 761138032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 761238032Speter The Timeout.* options are not safe -- they can be used to create a 761338032Speter denial-of-service attack. Problem noted by Christophe 761438032Speter Wolfhugel. 761543730Speter Don't send PostmasterCopy messages in the event of a "delayed" 761638032Speter notification. Suggested by Barry Bouwsma. 761738032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 761838032Speter option is set, since this disables VERB mode. Suggested 761938032Speter by John Hawkinson of MIT. 762038032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 762138032Speter by Motonori Nakamura of Kyoto University. 762238032Speter Only queue messages on transient .forward open failures if there 762343730Speter were no successful opens. The previous behavior caused it 762438032Speter to queue even if a "fall back" .forward was found. Problem 762538032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 762638032Speter and Computer Science (DISCS), NUS, Singapore. 762738032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 762838032Speter is bouncing because of a MIME error during 8->7 bit conversion; 762938032Speter the encapsulated message will bounce again, causing a loop. 763038032Speter Problem noted by Steve Hubert of the University of Washington. 763138032Speter Create xf (transcript) files using the TempFileMode option value 763238032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 763338032Speter National University of Singapore. 763438032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 763538032Speter detect cases where DefaultUid is set to something that the 763638032Speter system can't cope with. 763738032Speter PORTABILITY FIXES: 763838032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 763938032Speter Atlas International. 764038032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 764138032Speter <bicknell@ufp.org>. 764238032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 764338032Speter work on the first recipient of a message due to a 764438032Speter bug in the getpwent family.

Contributed by 768938032Speter Robert La Ferla of Hot Software. 769038032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 769138032Speter (where "code" is an exit status) on domains (previously 769238032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 769338032Speter Foundation. 769438032Speter CONFIG: hooks for IPv6-style domain literals. 769538032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 769638032Speter if it is undefined the AliasFile option is never set; this 769738032Speter should be transparent for most everyone. Suggested by John 769838032Speter Myers of CMU. 769938032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 770038032Speter domain listed in $=w is masqueraded. With it, only those 770138032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 770238032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 770338032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 770438032Speter hosts under those domains as well as the domain headers 770538032Speter themselves. For example, if a configuration had 770638032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 770738032Speter foo.com would be masqueraded; with it, *.foo.com would be 770838032Speter masqueraded as well. Based on an implementation by Richard 770938032Speter (Pug) Bainter of U. Texas. 771038032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 771138032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 771238032Speter Keys are user names; values are outgoing mail addresses. Yes, 771338032Speter this does overlap with the user database, and figuring out 771438032Speter just when to use which one may be tricky. Based on code 771538032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 771638032Speter from Per Hedeland of Ericsson. 771738032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 771838032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 771938032Speter Keys are either fully qualified addresses or just the host 772038032Speter part (with the @ sign). For example, a table containing: 772138032Speter info@foo.com foo-info 772238032Speter info@bar.com bar-info 772338032Speter @baz.org jane@elsewhere.net 772438032Speter would send all mail destined for info@foo.com to foo-info 772538032Speter (which is presumably an alias), mail addressed to info@bar.com 772638032Speter to bar-info, and anything addressed to anyone at baz.org will 772738032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 772838032Speter and baz.org must all be in $=w. Based on discussions with 772938032Speter a great many people. 773038032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 773138032Speter Suggested by Richard Bainter. 773238032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 773338032Speter "fax" mailer. 773438032Speter CONFIG: allow mailertable entries to resolve to local:user; this 773538032Speter passes the original user@host in to procmail-style local 773638032Speter mailers as the "detail" information to allow them to do 773738032Speter additional clever processing. From Joe Pruett of 773838032Speter Teleport Corporation. Delivery to the original user can 773938032Speter be done by specifying "local:" (with nothing after the colon). 774038032Speter CONFIG: allow any context that takes "mailer:domain" to also take 774138032Speter "mailer:user@domain" to force mailing to the given user; 774238032Speter "local:user" can also be used to do local delivery. This 774338032Speter applies on *_RELAY and in the mailertable entries. Based 774438032Speter on a suggestion by Ribert Kiessling of Easynet. 774538032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 774638032Speter limits the possible domains; this reduces the number of DNS 774738032Speter lookups required to support this feature. For example, 774838032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 774938032Speter to domains under my.site.com. Code contributed by Anthony 775038032Speter Thyssen <anthony@cit.gu.edu.au>. 775138032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 775238032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 775338032Speter of WPI. 775438032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 775538032Speter event you have to define local mailers. Suggested by 775638032Speter Gregory Shapiro of WPI. 775738032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 775838032Speter be misinterpreted as a list:...; syntax. Based on a patch by 775938032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 776038032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 776138032Speter remotely connected. The address host!user was being 776238032Speter converted to host!user@thishost instead of host!user@uurelay. 776338032Speter Problem noted by William Gianopoulos of Raytheon Company. 776438032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 776538032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 776638032Speter "User has moved"; the former wording was confusing if the 776738032Speter new address is still on the local host. Based on a suggestion 776838032Speter by Andreas Luik. 776938032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 777038032Speter However, the class is not pre-initialized to contain root. 777138032Speter Suggested by Gregory Neil Shapiro. 777238032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 777338032Speter Wolfhugel. 777438032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 777538032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 777638032Speter well: this produces a slightly different mailbox format (no 777738032Speter Content-Length: headers), file ownerships and modes are 777838032Speter different (not owned by group mail; mode 600 instead of 660), 777938032Speter and the local mailer flags will have to be tweaked (make them 778038032Speter match bsd4.4) in order to use this mailer. Patches from Paul 778138032Speter Hammann of the Missouri Research and Education Network. 778238032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 778338032Speter was a delivery error, such as if the ownership on the file 778438032Speter was wrong or the mode changed between the initial stat and 778538032Speter the open. Problem reported by William Colburn of the New 778638032Speter Mexico Institute of Mining and Technology. 778738032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 778838032Speter Costales. 778938032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 779038032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 779138032Speter honored. Fix from Michael Scott Shappe. 779238032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 779338032Speter NEW FILES: 779438032Speter src/Makefiles/Makefile.AIX.2 779538032Speter src/Makefiles/Makefile.IRIX.6.2 779638032Speter src/Makefiles/Makefile.maxion 779738032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 779838032Speter src/Makefiles/Makefile.SCO.5.x 779938032Speter src/Makefiles/Makefile.UXPDSV20 780038032Speter mailstats/mailstats.8 780138032Speter praliases/praliases.8 780238032Speter cf/cf/generic-nextstep3.3.mc 780338032Speter cf/feature/genericstable.m4 780438032Speter cf/feature/limited_masquerade.m4 780538032Speter cf/feature/masquerade_entire_domain.m4 780638032Speter cf/feature/virtusertable.m4 780738032Speter cf/ostype/aix2.m4 780838032Speter cf/ostype/altos.m4 780938032Speter cf/ostype/maxion.m4 781038032Speter cf/ostype/solaris2.ml.m4 781138032Speter cf/ostype/uxpds.m4 781238032Speter contrib/re-mqueue.pl 781338032Speter DELETED FILES: 781438032Speter src/Makefiles/Makefile.Solaris 781538032Speter contrib/xla/README 781638032Speter contrib/xla/xla.c 781738032Speter RENAMED FILES: 781838032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 781938032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 782038032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 782138032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 782238032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 782338032Speter 782464562Sgshapiro8.7.6/8.7.3 1996/09/17 782538032Speter SECURITY: It is possible to force getpwuid to fail when writing the 782638032Speter queue file, causing sendmail to fall back to running programs 782738032Speter as the default user. This is not exploitable from off-site. 782838032Speter Workarounds include using a unique user for the DefaultUser 782938032Speter (old u & g options) and using smrsh as the local shell. 783038032Speter SECURITY: fix some buffer overruns; in at least one case this allows 783138032Speter a local user to get root. This is not known to be exploitable 783238032Speter from off-site. The workaround is to disable chfn(1) commands. 783338032Speter 783464562Sgshapiro8.7.5/8.7.3 1996/03/04 783538032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 783638032Speter in some case cause connections to hang or messages to have 783738032Speter extra spaces in odd places. Patch from Eric Wassenaar; 783838032Speter reports from Eric Hall of Chiron Corporation, Stephen 783938032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 784038032Speter and others. 784138032Speter 784264562Sgshapiro8.7.4/8.7.3 1996/02/18 784338032Speter SECURITY: In some cases it was still possible for an attacker to 784438032Speter insert newlines into a queue file, thus allowing access to 784538032Speter any user (except root). 784638032Speter CONFIG: no changes -- it is not a bug that the configuration 784738032Speter version number is unchanged. 784838032Speter 784964562Sgshapiro8.7.3/8.7.3 1995/12/03 785038032Speter Fix botch in name server timeout in RCPT code; this problem caused 785138032Speter two responses in SMTP, which breaks things horribly. Fix 785238032Speter from Gregory Neil Shapiro of WPI. 785338032Speter Verify that L= value on M lines cannot be negative, which could cause 785438032Speter negative array subscripting. Not a security problem since 785538032Speter this has to be in the config file, but it could have caused 785638032Speter core dumps. Pointed out by Bryan Costales. 785738032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 785838032Speter Costales. 785938032Speter PORTABILITY FIXES: 786038032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 786138032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 786238032Speter order. Tweak it to work properly. Based on fixes 786338032Speter from Fletcher Mattox of UTexas and Betty Lee of 786438032Speter Stanford University. 786538032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 786638032Speter Deficiency pointed out by Bryan Costales of ICSI. 786738032Speter 786864562Sgshapiro8.7.2/8.7.2 1995/11/19 786938032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 787038032Speter OperatorChars, and UnixFromLine options. They were not 787138032Speter properly repaired in 8.7.1. 787238032Speter Completely delete the Bcc: header if and only if there are other 787338032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 787438032Speter last being a historic botch, of course). If Bcc: is the 787538032Speter only recipient header in the message, its value is tossed, 787643730Speter but the header name is kept. The old behavior (always keep 787738032Speter the header name and toss the value) allowed primary recipients 787838032Speter to see that a Bcc: went to _someone_. 787938032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 788038032Speter sender to <address> using -f'' syslog messages. Suggested 788138032Speter by Kari Hurtta. 788238032Speter If a sequence or switch map lookup entry gets a tempfail but then 788338032Speter continues on to another map type, but the name is not found, 788438032Speter return a temporary failure from the sequence or switch map. 788538032Speter For example, if hosts search ``dns files'' and DNS fails 788638032Speter with a tempfail, the hosts map will go on and search files, 788738032Speter but if it fails the whole thing should be a tempfail, not 788838032Speter a permanent (host unknown) failure, even though that is the 788938032Speter failure in the hosts.files map. This error caused hard 789038032Speter bounces when it should have requeued. 789138032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 789290792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 789338032Speter working properly due to excessive paranoia. Pointed out by 789438032Speter John Hawkinson of Panix. 789538032Speter An SMTP RCPT command referencing a host that gave a nameserver 789638032Speter timeout would return a 451 command (8.6 accepted it and 789743730Speter queued it locally). Revert to the 8.6 behavior in order 789838032Speter to simplify queue management for clustered systems. Suggested 789938032Speter by Gregory Neil Shapiro of WPI. The same problem could break 790038032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 790138032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 790238032Speter Infobiogen. 790338032Speter Fix possible buffer overflow in munchstring(). This was not a security 790438032Speter problem because you couldn't specify any argument to this 790538032Speter without first giving up root privileges, but it is still a 790638032Speter good idea to avoid future problems. Problem noted by John 790738032Speter Hawkinson and Sam Hartman of MIT. 790838032Speter ``452 Out of disk space for temp file'' messages weren't being 790938032Speter printed. Fix from David Perlin of Nanosoft. 791043730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 791138032Speter is not set, since this is required to get the actual DSNs 791238032Speter created. Problem pointed out by John Gardiner Myers of CMU. 791338032Speter Log permission problems that cause .forward and :include: files to 791438032Speter be untrusted or ignored on log level 12 and higher. Suggested 791538032Speter by Randy Martin of Clemson University. 791638032Speter Allow user ids in U= clauses of M lines to have hyphens and 791738032Speter underscores. 791838032Speter Fix overcounting of recipients -- only happened when sending to an 791938032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 792038032Speter of Systems and Computer Technology Corporation. 792138032Speter If a message is sent to an address that fails, the error message that 792238032Speter is returned could show some extraneous "success" information 792338032Speter included even if the user did not request success notification, 792438032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 792538032Speter Config files that had no AliasFile definition were defaulting to 792638032Speter using /etc/aliases; this caused problems with nullclient 792738032Speter configurations. Change it back to the 8.6 semantics of 792838032Speter having no local alias file unless it is declared. Problem 792938032Speter noted by Charles Karney of Princeton University. 793038032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 793138032Speter Costales of ICSI. 793238032Speter Map lookups of class "userdb" maps were always case sensitive; they 793338032Speter should be controlled by the -f flag like other maps. Pointed 793438032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 793538032Speter Fix problem that caused some addresses to be passed through ruleset 5 793638032Speter even when they were tagged as "sticky" by prefixing the 793738032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 793838032Speter Technological University. 793938032Speter When converting a message to Quoted-Printable, prevent any lines with 794038032Speter dots alone on a line by themselves. This is because of the 794138032Speter preponderance of broken mailers that still get this wrong. 794238032Speter Code contributed by Per Hedeland of Ericsson. 794338032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 794438032Speter out by Bjart Kvarme of USIT/UiO (Norway). 794538032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 794638032Speter Requested by Allan Johannesen. 794738032Speter Delete check for text format of alias files -- it should be legal 794838032Speter to have the database format of the alias files without the 794938032Speter text version. Problem pointed out by Joe Rhett of Navigist, 795038032Speter Inc. 795138032Speter If "Ot" was specified with no value, the TZ variable was not properly 795238032Speter imported from the environment. Pointed out by Frank Crawford 795338032Speter <frank@ansto.gov.au>. 795438032Speter Some architectures core dumped on "program" maps that didn't have 795538032Speter extra arguments. Patch from Booker C. Bense of Stanford 795638032Speter University. 795738032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 795838032Speter the parent should do this. Fix from Brian Coan of the 795938032Speter Association for Progressive Communications. 796038032Speter If MinQueueAge was set and a message was considered but not run 796138032Speter during a queue run and the Timeout.queuereturn interval was 796238032Speter reached, a "timed out" error message would be returned that 796338032Speter didn't include the failed address (and claimed to be a warning 796438032Speter even though it was fatal). The fix is to not return such 796538032Speter messages until they are actually tried, i.e., in the next 796638032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 796738032Speter SINTEF RUNIT, Oslo. 796838032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 796938032Speter that have the hes_getmailhost() routine.

Bug 801638032Speter pointed out by John Hawkinson of MIT. 801738032Speter Fix strange case of an executable called by a program map that 801838032Speter returns a value but also a non-zero exit status; this 801938032Speter would give contradictory results in the higher level; in 802038032Speter particular, the default clause in the map lookup would be 802138032Speter ignored. Change to ignore the value if the program returns 802238032Speter non-zero exit status. From Tom Moore of AT&T GIS. 802338032Speter Shorten parameters passed to syslog() in some contexts to avoid a 802438032Speter bug in many vendors' implementations of that routine. Although 802538032Speter this isn't really a bug in sendmail per se, and my solution 802638032Speter has to assume that syslog() has at least a 1K buffer size 802738032Speter internally (I know some vendors have shortened this 802838032Speter dramatically -- they're on their own), sendmail is a popular 802938032Speter target. Also, limit the size of %s arguments in sprintf. 803038032Speter These both have possible security implications. Solutions 803138032Speter suggested by Casper Dik of Sun's Network Security Group 803238032Speter (Holland), Mark Seiden, and others. 803338032Speter Fix a problem that might cause a non-standard -B (body type) 803438032Speter parameter to be passed to the next server with undefined 803538032Speter results. This could have security implications. 803638032Speter If a filesystem was at > 100% utilization, the freediskspace() 803738032Speter routine incorrectly returned an error rather than zero. 803838032Speter Problem noted by G. Paul Ziemba of Alantec. 803938032Speter Change MX sort order so that local hostnames (those in $=w) always 804038032Speter sort first within a given preference. This forces the bestmx 804138032Speter map to always return the local host first, if it is included 804238032Speter in the list of highest priority MX records. From K. Robert 804338032Speter Elz. 804438032Speter Avoid some possible null pointer dereferences. Fixes from Randy 804538032Speter Martin <WOLF@CLEMSON.EDU> 804638032Speter When sendmail starts up on systems that have no fully qualified 804738032Speter domain name (FQDN) anywhere in the first matching host map 804838032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 804938032Speter sendmail would sleep to try to find a FQDN, which it really 805038032Speter really needs. This has been changed to fall through to the 805138032Speter next map type if it can't find a FQDN -- i.e., if the hosts 805238032Speter file doesn't have a FQDN, it will try dns even though the 805338032Speter short name was found in /etc/hosts. This is probably a crock, 805438032Speter but many people have hosts files without FQDNs. Remember: 805538032Speter domain names are your friends. 805638032Speter Log a high-priority message if you can't find your FQDN during startup. 805738032Speter Suggested by Simon Barnes of Schlumberger Limited. 805838032Speter When using Hesiod, initialize it early to improve error reporting. 805938032Speter Patch from Don Lewis of Silicon Systems, Inc. 806038032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 806138032Speter connection timeout in the kernel. Add a new "connect" timeout 806238032Speter to limit this time. Defaults to zero (use whatever the 806338032Speter kernel provides). Based on code contributed by J.R. Oldroyd 806438032Speter of TerraNet. 806538032Speter Under some circumstances, a failed message would not be properly 806638032Speter removed from the queue, causing tons of bogus error messages. 806738032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 806838032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 806938032Speter of WPI. 807038032Speter PORTABILITY FIXES: 807138032Speter On IRIX 5.x, there was an inconsistency in the setting 807238032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 808838032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 808938032Speter otherwise the F=S causes the From_ line to imply that root is 809038032Speter the sender. Problem pointed out by Claude Scarpelli of 809138032Speter Infobiogen (France). 809238032Speter NEW FILES: 809338032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 809438032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 809538032Speter src/Makefiles/Makefile.UXPDS 809638032Speter 809764562Sgshapiro8.7/8.7 1995/09/16 809838032Speter Fix a problem that could cause sendmail to run out of file 809938032Speter descriptors due to a trashed data structure after a 810038032Speter vfork.

This was used "safely" in the sense 810638032Speter that it only did a stat, but it would have set the 810738032Speter map modification time improperly. Problem pointed out 810838032Speter by Roy Mongiovi of Georgia Tech. 810938032Speter Clean up the Subject: line on warning messages and return 811038032Speter receipts so that they don't say "Returned mail:"; this 811138032Speter can be confusing. 811238032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 811338032Speter useful enough to make it worthwhile printing on "-d". 811438032Speter Avoid logging alias statistics every time you read the alias 811538032Speter file on systems with no database method compiled in. 811638032Speter If you have a name with a trailing dot, and you try looking it 811738032Speter up using gethostbyname without the dot (for /etc/hosts 811838032Speter compatibility), be sure to turn off RES_DEFNAMES and 811938032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 812038032Speter Problem noted by Charles Amos of the University of 812138032Speter Maryland. 812238032Speter Don't do timeouts in collect if you are not running SMTP. 812338032Speter There is nothing that says you can't have a long 812438032Speter running program piped into sendmail (possibly via 812538032Speter /bin/mail, which just execs sendmail). Problem reported 812638032Speter by Don "Truck" Lewis of Silicon Systems. 812738032Speter Try gethostbyname() even if the DNS lookup fails iff option I 812838032Speter is not set. This allows you to have hosts listed in 812938032Speter NIS or /etc/hosts that are not known to DNS. It's normally 813038032Speter a bad idea, but can be useful on firewall machines. This 813138032Speter should really be broken out on a separate flag, I suppose. 813238032Speter Avoid compile warnings against BIND 4.9.3, which uses function 813338032Speter prototypes.

From Kyle Jones of UUNET. 813838032Speter SECURITY: avoid denial-of-service attacks possible by destroying 813938032Speter the alias database file by setting resource limits low. 814038032Speter This involves adding two new compile-time options: 814138032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 814238032Speter available) and HASULIMIT (indicating that ulimit(2) support 814338032Speter is available -- the Release 3 form is used). The former 814438032Speter is assumed on BSD-based systems, the latter on System 814538032Speter V-based systems. Attack noted by Phil Brandenberger of 814638032Speter Swarthmore University. 814738032Speter New syntaxes in test (-bt) mode: 814838032Speter ``.Dmvalue'' will define macro "m" to "value". 814938032Speter ``.Ccvalue'' will add "value" to class "c". 815038032Speter ``=Sruleset'' will dump the contents of the indicated 815138032Speter ruleset. 815238032Speter ``=M'' will display the known mailers. 815338032Speter ``-ddebug-spec'' is equivalent to the command-line 815438032Speter -d debug flag. 815538032Speter ``$m'' will print the value of macro $m. 815638032Speter ``$=c'' will print the contents of class $=c. 815738032Speter ``/mx host'' returns the MX records for ``host''. 815838032Speter ``/parse address'' will parse address, returning the value of 815938032Speter crackaddr (essentially, the comment information) 816038032Speter and the parsed address. 816138032Speter ``/try mailer address'' will rewrite address into the form 816238032Speter it will have when presented to the indicated mailer. 816338032Speter ``/tryflags flags'' will set flags used by parsing. The 816438032Speter flags can be `H' for header or `E' for envelope, 816538032Speter and `S' for sender or `R' for recipient. These 816638032Speter can be combined, so `HR' sets flags for header 816738032Speter recipients. 816838032Speter ``/canon hostname'' will try to canonify hostname and 816938032Speter return the result. 817038032Speter ``/map mapname key'' will look up `key' in the indicated 817138032Speter `mapname' and return the result. 817238032Speter Somewhat better handling of UNIX-domain socket addresses -- it 817338032Speter should show the pathname rather than hex bytes. 817438032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 817538032Speter the header for envelope sender information and uses 817638032Speter CR-LF as message terminators. It was thought to be 817738032Speter obsolete (used only for Arpanet NCP protocols), but it 817838032Speter turns out that the UK ``Grey Book'' protocols require 817938032Speter that functionality. 818038032Speter Fix a fix in previous release -- if gethostname and gethostbyname 818138032Speter return a name without dots, and if an attempt to canonify 818238032Speter that name fails, wait one minute and try again. This can 818338032Speter result in an extra 60 second delay on startup if your system 818438032Speter hostname (as returned by hostname(1)) has no dot and no names 818538032Speter listed in /etc/hosts or your NIS map have a dot. 818638032Speter Check for proper domain name on HELO and EHLO commands per 818738032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 818838032Speter of Michigan Technological University. 818938032Speter Relax chownsafe rules slightly -- old version said that if you 819038032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 819138032Speter if fpathconf returned EINVAL or ENOSYS), assume that 819238032Speter chown is not safe. The new version falls back to whether 819338032Speter you are on a BSD system or not. This is important for 819438032Speter SunOS, which apparently always returns one of those 819538032Speter error codes. This impacts whether you can mail to files 819638032Speter or not. 819738032Speter Syntax errors such as unbalanced parentheses in the configuration 819838032Speter file could be omitted if you had "Oem" prior to the 819938032Speter syntax error in the config file. Change to always print 820038032Speter the error message. It was especially weird because it 820138032Speter would cause a "warning" message to be sent to the Postmaster 820238032Speter for every message sent (but with no transcript). Problem 820338032Speter noted by Gregory Paris of Motorola. 820438032Speter Rewrite collect and putbody to handle full 8-bit data, including 820538032Speter zero bytes.

This is to handle the 827438032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 827538032Speter assume that ``group name:'' is a comment on the first 827638032Speter address and the ``;'' is a comment on the last address). 827738032Speter This requires config file support to get right. It does 827838032Speter understand that :: is NOT this syntax, and can be turned 827938032Speter off completely by setting the ColonOkInAddresses option. 828038032Speter Level 6 config files added with new mailer flags: 828138032Speter A Addresses are aliasable. 828238032Speter i Do udb rewriting on envelope as well as header 828338032Speter sender lines. Applies to the from address mailer 828438032Speter flags rather than the recipient mailer flags. 828538032Speter j Do udb rewriting on header recipient addresses. 828638032Speter Applies to the sender mailer flags rather than the 828738032Speter recipient mailer flags. 828838032Speter k Disable check for loops when doing HELO command. 828938032Speter o Always run as the mail recipient, even on local 829038032Speter delivery. 829138032Speter w Check for an /etc/passwd entry for this user. 829238032Speter 5 Pass addresses through ruleset 5. 829338032Speter : Check for :include: on this address. 829438032Speter | Check for |program on this address. 829538032Speter / Check for /file on this address. 829638032Speter @ Look up sender header addresses in the user 829738032Speter database. Applies to the mailer flags for the 829838032Speter mailer corresponding to the envelope sender 829938032Speter address, rather than to recipient mailer flags. 830038032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 830138032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 830238032Speter mailers, and the ColonOkInAddresses option. 830338032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 830438032Speter John Beck of Hewlett-Packard, who generously contributed 830538032Speter their implementation to me, which I then didn't use (see 830638032Speter mime.c for an explanation of why). This adds the 830738032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 830838032Speter to control handling of 8-bit data. These have to cope with 830938032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 831038032Speter 8-bit data that is entered without declaring it as 8-bit 831138032Speter MIME -- technically this is illegal according to the 831238032Speter specs) and labelled 8-bit data (that is, it was declared 831338032Speter as 8BITMIME in the ESMTP session or by using the 831438032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 831538032Speter set then 8-bit data is sent to non-8BITMIME machines 831638032Speter instead of converting to 7 bit (essentially using 831738032Speter just-send-8 semantics). The values for EightBitMode are: 831838032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 831938032Speter any necessary conversion of 8BITMIME to 7BIT 832038032Speter (essentially, the full MIME option). 832138032Speter p pass unlabelled 8-bit input, but convert labelled 832238032Speter 8BITMIME input to 7BIT as required (default). 832338032Speter s strict adherence: reject unlabelled 8-bit input, 832438032Speter convert 8BITMIME to 7BIT as required. The F=8 832538032Speter flag is ignored. 832638032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 832738032Speter the setting of F=8. 832838032Speter Add new internal class 'n', which is the set of MIME Content-Types 832938032Speter which can not be 8 to 7 bit encoded because of other 833038032Speter considerations. Types "multipart/*" and "message/*" are 833138032Speter never directly encoded (although their components can be). 833238032Speter Add new internal class 's', which is the set of subtypes of the 833338032Speter MIME message/* content type that can be treated as though 833438032Speter they are an RFC822 message. It is predefined to have 833538032Speter "rfc822". Suggested By Kari Hurtta. 833638032Speter Add new internal class 'e'. This is the set of MIME 833738032Speter Content-Transfer-Encodings that can be converted to 833838032Speter a seven bit format (Quoted-Printable or Base64). It is 833938032Speter preinitialized to contain "7bit", "8bit", and "binary". 834038032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 834138032Speter short name) to set the default character set to use in the 834238032Speter Content-Type: header when doing encoding of an 8-bit message 834338032Speter which isn't marked as MIME into MIME format. If the C= 834438032Speter parameter is set on the Envelope From address, use that as 834538032Speter the default encoding; else use the DefaultCharSet option. 834638032Speter If neither is set, it defaults to "unknown-8bit" as 834738032Speter suggested by RFC 1428 section 3. 834838032Speter Allow ``U=user:group'' field in mailer definition to set a default 834938032Speter user and group that a mailer will be executed as. This 835038032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 835138032Speter also set, it is the uid/gid that will always be used (that 835238032Speter is, the controlling address is ignored). The values may be 835338032Speter numeric or symbolic; if only a symbolic user is given (no 835438032Speter group) that user's default group in the passwd file is used 835538032Speter as the group. Based on code donated by Chip Rosenthal of 835638032Speter Unicom. 835738032Speter Allow `u' option to also accept user:group as a value, in the same 835838032Speter fashion as the U= mailer option. 835938032Speter Add the symbolic time zone name in the Arpanet format dates (as 836038032Speter a comment). This adds a new compile-time configuration 836138032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 836238032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 836338032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 836438032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 836538032Speter timezone()), or TZ_NONE (don't include the comment). Code 836638032Speter from Chip Rosenthal. 836738032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 836838032Speter For example, 836938032Speter O Timeout.helo = 2m 837038032Speter There are also two new suboptions "queuereturn" and 837138032Speter "queuewarn"; these subsume the old T option. Thus, to 837238032Speter set them both the preferred new syntax is 837338032Speter O Timeout.queuereturn = 5d 837438032Speter O Timeout.queuewarn = 4h 837538032Speter Sort queue by host name instead of by message priority if the 837638032Speter QueueSortOrder option (no short name) is set is set to 837738032Speter ``host''. This makes better use of the connection cache, 837838032Speter but may delay more ``interactive'' messages behind large 837938032Speter backlogs under some circumstances. This is probably a 838038032Speter good option if you have high speed links or don't do lots 838138032Speter of ``batch'' messages, but less good if you are using 838238032Speter something like PPP on a 14.4 modem. Based on code 838338032Speter contributed by Roy Mongiovi of Georgia Tech (my main 838438032Speter contribution was to make it configurable). 838538032Speter Save i-number of df file in qf file to simplify rebuilding of queue 838638032Speter after disastrous disk crash. Suggested by Kyle Jones of 838738032Speter UUNET; closely based on code from KJS DECWRL code written 838838032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 838938032Speter are NOT back compatible with 8.6 -- that is, you can convert 839038032Speter from 8.6 to 8.7, but not the other direction. 839138032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 839238032Speter route-addrs in envelopes; this is because in some cases 839338032Speter they can be sent to the shell, which interprets them as 839438032Speter I/O redirection. 839538032Speter Don't include error file (option E) with return-receipts; this 839638032Speter can be confusing. 839738032Speter Don't send "Warning: cannot send" messages to owner-* or 839838032Speter *-request addresses. Suggested by Christophe Wolfhugel 839938032Speter of the Institut Pasteur, Paris. 840038032Speter Allow -O command line flag to set long form options. 840138032Speter Add "MinQueueAge" option to set the minimum time between attempts 840238032Speter to run the queue. For example, if the queue interval 840338032Speter (-q value) is five minutes, but the minimum queue age 840438032Speter is fifteen minutes, jobs won't be tried more often than 840538032Speter once every fifteen minutes. This can be used to give 840638032Speter you more responsiveness if your delivery mode is set to 840738032Speter queue-only. 840838032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 840938032Speter :include: and .forward files. 841038032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 841138032Speter key field name, the value field name, and the field 841238032Speter delimiter. The field delimiter can be a single character 841338032Speter or the sequence "\t" or "\n" for tab or newline. 841438032Speter These are for use by NIS+ and similar access methods. 841538032Speter Change maps to always strip quotes before lookups; the -q flag 841643730Speter turns off this behavior. Suggested by Motonori Nakamura. 841738032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 841838032Speter key and value field names respectively. Code donated by 841938032Speter Sun Microsystems. 842038032Speter Add "hesiod" map class. The "file name" is used as the 842138032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 842238032Speter first value found for the match. Code donated by Scott 842338032Speter Hutton of Indiana University. 842438032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 842538032Speter specify the name of the property that is searched as the 842638032Speter key and a -v flag to specify the name of the property that 842738032Speter is returned as the value (defaults to "members"). The 842838032Speter default map is "/aliases". Some code based on code 842938032Speter contributed by Robert La Ferla of Hot Software. 843038032Speter Add "text" map class. This does slow, linear searches through 843138032Speter text files. The -z flag specifies a column delimiter 843238032Speter (defaults to any sequence of white space), the -k flag 843338032Speter sets the key column number, and the -v flag sets the 843438032Speter value column number. Lines beginning with `#' are treated 843538032Speter as comments. 843638032Speter Add "program" map class to execute arbitrary programs. The search 843738032Speter key is presented as the last argument; the output is one 843838032Speter line read from the programs standard output. Exit statuses 843938032Speter are from sysexits.h. 844038032Speter Add "sequence" map class -- searches maps in sequence until it 844138032Speter finds a match. For example, the declarations: 844238032Speter Kmap1 ... 844338032Speter Kmap2 ... 844438032Speter Kmapseq sequence map1 map2 844538032Speter defines a map "mapseq" that first searches map1; if the 844638032Speter value is found it is returned immediately, otherwise 844738032Speter map2 is searched and the value returned. 844838032Speter Add "switch" map class. This is much like "sequence" except that 844938032Speter the ordering is fetched from an external file, usually 845038032Speter the system service switch. The parameter is the name of 845138032Speter the service to switch on, and the maps that it will use 845238032Speter are the name of the switch map followed by ".service_type". 845338032Speter For example, if the declaration of the map is 845438032Speter Ksample switch hosts 845538032Speter and the system service switch specifies that hosts are 845638032Speter looked up using dns and nis in that order, then this is 845738032Speter equivalent to 845838032Speter Ksample sequence sample.dns sample.nis 845938032Speter The subordinate maps (sample.*) must already be defined. 846038032Speter Add "user" map class -- looks up users using getpwnam. Takes a 846138032Speter "-v field" flag on the definition that tells what passwd 846238032Speter entry to return -- legal values are name, passwd, uid, gid, 846338032Speter gecos, dir, and shell. Generally expected to be used with 846438032Speter the -m (matchonly) flag. 846538032Speter Add "bestmx" map class -- returns the best MX value for the host 846638032Speter listed as the value. If there are several "best" MX records 846738032Speter for this host, one will be chosen at random. 846838032Speter Add "userdb" map class -- looks up entries in the user database. 846938032Speter The "file name" is actually the tag that will be used, 847038032Speter typically "mailname". If there are multiple entries 847138032Speter matching the name, the one chosen is undefined. 847238032Speter Add multiple queue timeouts (both return and warning). These are 847338032Speter set by the Precedence: or Priority: header fields to one of 847438032Speter three values. If a Priority: is set and has value "normal", 847564562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 847638032Speter used. If no priority is set, the Precedence: is consulted; 847738032Speter if negative, non-urgent timeouts are used; if greater than 847838032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 847938032Speter are used. The timeouts are set by setting the six timeouts 848038032Speter queue{warn,return}.{urgent,normal,non-urgent}. 848138032Speter Fix problem when a mail address is resolved to a $#error mailer 848238032Speter with a temporary failure indication; it works in SMTP, 848338032Speter but when delivering locally the mail is silently discarded. 848438032Speter This patch, from Kyle Jones of UUNET, bounces it instead 848538032Speter of queueing it (queueing is very hard). 848638032Speter When using /etc/hosts or NIS-style lookups, don't assume that 848738032Speter the first name in the list is the best one -- instead, 848838032Speter search for the first one with a dot. For example, if 848938032Speter an /etc/hosts entry reads 849038032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 849138032Speter this change will use the second name as the canonical 849238032Speter machine name instead of the initial, unqualified name. 849338032Speter Change dequote map to replace spaces in quoted text with a value 849438032Speter indicated by the -s flag on the dequote map definition. 849538032Speter For example, ``Mdequote dequote -s_'' will change 849638032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 849738032Speter quoted (because of the space character). Suggested by Dan 849838032Speter Oscarsson for use in X.400 addresses. 849938032Speter Implement long macro names as ${name}; long class names can 850038032Speter be similarly referenced as $={name} and $~{name}. 850138032Speter Definitions are (e.g.) ``D{name}value''. Names that have 850238032Speter a leading lower case letter or punctuation characters are 850338032Speter reserved for internal use by sendmail; i.e., config files 850438032Speter should use names that begin with a capital letter. Based 850538032Speter on code contributed by Dan Oscarsson. 850638032Speter Fix core dump if getgrgid returns a null group list (as opposed 850738032Speter to an empty group list, that is, a pointer to a list 850838032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 850938032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 851038032Speter failed, it called syserr which called newstr which called 851138032Speter xalloc.... The newstr is now avoided for "panic" messages. 851238032Speter Reported by Stuart Kemp of James Cook University. 851338032Speter Improve connection cache timeouts; previously, they were not even 851438032Speter checked if you were delivering to anything other than an 851538032Speter IPC-connected host, so a series of (say) local mail 851638032Speter deliveries could cause cached connections to be open 851738032Speter much longer than the specified timeout. 851838032Speter If an incoming message exceeds the maximum message size, stop 851938032Speter writing the incoming bytes to the queue data file, since 852038032Speter this can fill your mqueue partition -- this is a possible 852138032Speter denial-of-service attack. 852238032Speter Don't reject all numeric local user names unless HESIOD is 852338032Speter defined. It turns out that Posix allows all-numeric 852438032Speter user names. Fix from Tony Sanders of BSDI. 852538032Speter Add service switch support. If the local OS has a service 852638032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 852738032Speter on DEC systems) that will be used; otherwise, it falls back 852838032Speter to using a local mechanism based on the ServiceSwitchFile 852938032Speter option (default: /etc/service.switch). For example, if the 853038032Speter service switch lists "files" and "nis" for the aliases 853138032Speter service, that will be the default lookup order. the "files" 853238032Speter ("local" on DEC) service type expands to any alias files 853338032Speter you listed in the configuration file, even if they aren't 853438032Speter actually file lookups. 853538032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 853638032Speter variable which tells whether or not DNS should be considered 853738032Speter canonical. This is now determined based on whether or not 853838032Speter "dns" is in the service list for "hosts". 853938032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 854038032Speter Status Notifications). DSN notifications override 854138032Speter Return-Receipt-To: headers, which are bogus anyhow -- 854238032Speter support for them has been removed. 854338032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 854438032Speter definitions to define the types used in DSN returns for 854538032Speter MTA names, addresses, and diagnostics respectively. 854638032Speter Extend heuristic to force running in ESMTP mode to look for the 854738032Speter five-character string "ESMTP" anywhere in the 220 greeting 854838032Speter message (not just the second line). This is to provide 854938032Speter better compatibility with other ESMTP servers. 855038032Speter Print sequence number of job when running the queue so you can 855138032Speter easily see how much progress you have made. Suggested 855238032Speter by Peter Wemm of DIALix. 855338032Speter Map newlines to spaces in logged message-ids; some versions of 855438032Speter syslog truncate the rest of the line after newlines. 855538032Speter Suggested by Fletcher Mattox of U. Texas. 855638032Speter Move up forking for job runs so that if a message is split into 855738032Speter multiple envelopes you don't get "fork storms" -- this 855838032Speter also improves the connection cache utilization. 855938032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 856038032Speter the purposes of refusing to send error returns. Suggested 856138032Speter by Motonori Nakamura of Ritsumeikan University. 856238032Speter Relax rules on when a file can be written when referenced from 856338032Speter the aliases file: use the default uid/gid instead of the 856438032Speter real uid/gid. This allows you to create a file owned by 856538032Speter and writable only by the default uid/gid that will work 856690792Sgshapiro all the time (without having the set-user-ID bit set). Change 856738032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 856838032Speter Microsystems. 856938032Speter Add "DialDelay" option (no short name) to provide an "extra" 857038032Speter delay for dial on demand systems. If this is non-zero 857138032Speter and a connect fails, sendmail will wait this long and 857238032Speter then try again. If it takes longer than the kernel 857338032Speter timeout interval to establish the connection, this 857438032Speter option can give the network software time to establish 857538032Speter the link. The default units are seconds. 857638032Speter Move logging of sender information to be as early as possible; 857738032Speter previously, it could be delayed a while for SMTP mail 857838032Speter sent to aliases. Suggested by Brad Knowles of the 857938032Speter Defense Information Systems Agency. 858038032Speter Call res_init() before setting RES_DEBUG; this is required by 858138032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 858238032Speter the National Computer Security Center. 858338032Speter Add xdelay= field in logs -- this is a transaction delay, telling 858438032Speter you how long it took to deliver to this address on the 858538032Speter last try. It is intended to be used for sorting mailing 858638032Speter lists to favor "quick" addresses. Provided for use by 858738032Speter the mailprio scripts (see below). 858838032Speter If a map cannot be opened, and that map is non-optional, and 858938032Speter an address requires that map for resolution, queue the 859038032Speter map instead of bouncing it. This involves creating a 859138032Speter pseudo-class of maps called "bogus-map" -- if a required 859238032Speter map cannot be opened, the class is changed to bogus-map; 859338032Speter all queries against bogus-map return "tempfail". The 859438032Speter bogus-map class is not directly accessible. A sample 859538032Speter implementation was donated by Jem Taylor of Glasgow 859638032Speter University Computing Service. 859738032Speter Fix a possible core dump when mailing to a program that talks 859838032Speter SMTP on its standard input. Fix from Keith Moore of 859938032Speter the University of Kentucky. 860038032Speter Make it possible to resolve filenames to $#local $: @ /filename; 860138032Speter previously, the "@" would cause it to not be recognized 860238032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 860338032Speter Accept a -1 signal to re-exec the daemon. This only works if 860438032Speter argv[0] is a full path to sendmail. 860538032Speter Fix bug in "addr=..." field in O option on little-endian machines 860638032Speter -- the network number wasn't being converted to network 860738032Speter byte order. Patch from Kurt Lidl of Pix Technologies 860838032Speter Corporation. 860938032Speter Pre-initialize the resolver early on; this is to avoid a bug with 861038032Speter BIND 4.9.3 that can cause the _res.retry field to get 861138032Speter reset to zero, causing all name server lookups to time 861238032Speter out. Fix from Matt Day of Artisoft. 861338032Speter Restore T line (trusted users) in config file -- but instead of 861438032Speter locking out the -f flag, they just tell whether or not 861538032Speter an X-Authentication-Warning: will be added. This really 861638032Speter just creates new entries in class 't', so "Ft/file/name" 861738032Speter can be used to read trusted user names from a file. 861838032Speter Trusted users are also allowed to execute programs even 861938032Speter if they have a shell that isn't in /etc/shells. 862038032Speter Improve NEWDB alias file rebuilding so it will create them 862138032Speter properly if they do not already exist. This had been 862238032Speter a MAYBENEXTRELEASE feature in 8.6.9. 862338032Speter Check for @:@ entry in NIS maps before starting up to avoid 862438032Speter (but not prevent, sigh) race conditions. This ought to 862538032Speter be handled properly in ypserv, but isn't. Suggested by 862638032Speter Michael Beirne of Motorola. 862738032Speter Refuse connections if there isn't enough space on the filesystem 862838032Speter holding the queue. Contributed by Robert Dana of Wolf 862938032Speter Communications. 863038032Speter Skip checking for directory permissions in the path to a file 863138032Speter when checking for file permissions iff setreuid() 863238032Speter succeeded -- it is unnecessary in that case. This avoids 863338032Speter significant performance problems when looking for .forward 863438032Speter files. Based on a suggestion by Win Bent of USC. 863538032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 863638032Speter arbitrary ruleset number assigned or "Sname = integer" 863738032Speter to assign a specific ruleset number. Reference is 863838032Speter $>name_or_number. Names can be composed of alphas, digits, 863938032Speter underscore, or hyphen (first character must be non-numeric). 864038032Speter Allow -o flag on AliasFile lines to make the alias file optional. 864138032Speter From Bryan Costales of ICSI. 864238032Speter Add NoRecipientAction option to handle the case where there is 864338032Speter no legal recipient header in the message. It can take 864438032Speter on values: 864538032Speter None Leave the message as is. The 864638032Speter message will be passed on even 864738032Speter though it is in technically 864838032Speter illegal syntax. 864938032Speter Add-To Add a To: header with any 865038032Speter recipients that it can find from 865138032Speter the envelope. This risks exposing 865238032Speter Bcc: recipients. 865338032Speter Add-Apparently-To Add an Apparently-To: header. This 865438032Speter has almost no redeeming social value, 865538032Speter and is provided only for back 865638032Speter compatibility. 865738032Speter Add-To-Undisclosed Add a header reading 865838032Speter To: undisclosed-recipients:; 865938032Speter which will have the effect of 866038032Speter making the message legal without 866138032Speter exposing Bcc: recipients. 866238032Speter Add-Bcc To add an empty Bcc: header. 866338032Speter There is a chance that mailers down 866438032Speter the line will delete this header, 866538032Speter which could cause exposure of Bcc: 866638032Speter recipients. 866738032Speter The default is NoRecipientAction=None. 866838032Speter Truncate (rather than delete) Bcc: lines in the header. This 866938032Speter should prevent later sendmails (at least, those that don't 867038032Speter themselves delete Bcc:) from considering this message to 867138032Speter be non-conforming -- although it does imply that non-blind 867238032Speter recipients can see that a Bcc: was sent, albeit not to whom. 867338032Speter Add SafeFileEnvironment option. If declared, files named as delivery 867438032Speter targets must be regular files in addition to the regular 867538032Speter checks. Also, if the option is non-null then it is used as 867638032Speter the name of a directory that is used as a chroot(2) 867738032Speter environment for the delivery; the file names listed in an 867838032Speter alias or forward should include the name of this root. 867938032Speter For example, if you run with 868038032Speter O SafeFileEnvironment=/arch 868138032Speter then aliases should reference "/arch/rest/of/path". If a 868238032Speter value is given, sendmail also won't try to save to 868338032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 868438032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 868538032Speter Support -A flag for alias files; this will comma concatenate like 868638032Speter entries. For example, given the aliases: 868738032Speter list: member1 868838032Speter list: member2 868938032Speter and an alias file declared as: 869038032Speter OAhash:-A /etc/aliases 869138032Speter the final alias inserted will be "list: member1,member2"; 869238032Speter without -A you will get an error on the second and subsequent 869338032Speter alias for "list". Contributed by Bryan Costales of ICSI. 869438032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 869538032Speter Fix a problem that could cause very long addresses to core dump in 869638032Speter some special circumstances. Problem pointed out by Allan 869738032Speter Johannesen. 869838032Speter (Internal change.) Change interface to expand() (macro expansion) 869938032Speter to be simpler and more consistent. 870038032Speter Delete check for funny qf file names. This didn't really give 870138032Speter any extra security and caused some people some problems. 870238032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 870338032Speter at compile time.) Suggested by Kyle Jones of UUNET. 870438032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 870538032Speter merge with DSN code; this is simpler and more consistent. 870638032Speter This may affect some people who have written their own 870738032Speter checkcompat() routine. 870838032Speter (Internal change.) Eliminate `D' line in qf file. The df file 870938032Speter is now assumed to be the same name as the qf file (with 871038032Speter the `q' changed to a `d', of course). 871138032Speter Avoid forking for delivery if all recipient mailers are marked as 871238032Speter "expensive" -- this can be a major cost on some systems. 871338032Speter Essentially, this forces sendmail into "queue only" mode 871438032Speter if all it is going to do is queue anyway. 871538032Speter Avoid sending a null message in some rather unusual circumstances 871638032Speter (specifically, the RCPT command returns a temporary 871738032Speter failure but the connection is lost before the DATA 871838032Speter command). Fix from Scott Hammond of Secure Computing 871938032Speter Corporation. 872038032Speter Change makesendmail to use a somewhat more rational naming scheme: 872138032Speter Makefiles and obj directories are named $os.$rel.$arch, 872238032Speter where $os is the operating system (e.g., SunOS), $rel is 872338032Speter the release number (e.g., 5.3), and $arch is the machine 872438032Speter architecture (e.g., sun4). Any of these can be omitted, 872538032Speter and anything after the first dot in a release number can 872638032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 872738032Speter version used $os.$arch.$rel and was rather less general. 872838032Speter Change makesendmail to do a "make depend" in the target directory 872938032Speter when it is being created. This involves adding an empty 873038032Speter "depend:" entry in most Makefiles. 873138032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 873238032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 873338032Speter of the Finnish Meteorological Institute. 873438032Speter Fix problem that could cause multiple responses to DATA command 873538032Speter on header syntax errors (e.g., lines beginning with colons). 873638032Speter Problem noted by Jens Thomassen of the University of Oslo. 873738032Speter Don't let null bytes in headers cause truncation of the rest of 873838032Speter the header. 873938032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 874038032Speter Increase timeouts on message data puts to allow time for receivers 874138032Speter to canonify addresses in headers on the fly. This is still 874238032Speter a rather ugly heuristic. From Motonori Nakamura. 874338032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 874438032Speter records are not used when canonifying names, and when MX 874538032Speter lookups are done for addressing they must be fully 874638032Speter qualified. This is useful if you have a wildcard MX record, 874738032Speter although it may cause other problems. In general, don't use 874838032Speter wildcard MX records. Patch from Motonori Nakamura. 874938032Speter Eliminate default two-line SMTP greeting message. Instead of 875038032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 875138032Speter is added between the first and second word of the first 875238032Speter line of the greeting message (i.e., immediately after the 875338032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 875438032Speter compile flag. Old sendmails won't see the ESMTP, but that's 875538032Speter acceptable because SIZE was the only useful extension that 875638032Speter old sendmails understand. 875738032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 875838032Speter invoked state dumps. From Masaharu Onishi. 875938032Speter Allow on-line comments in .forward and :include: files; they are 876038032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 876138032Speter is a space or a tab. This is intended for native 876238032Speter representation of non-ASCII sets such as Japanese, where 876338032Speter existing encodings would be unreadable or would lose 876438032Speter data -- for example, 876538032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 876638032Speter (romanized/less information) 876738032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 876838032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 876938032Speter (with MIME encoding, not human readable) 877038032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 877138032Speter (native encoding with ISO-2022-JP) 877238032Speter The last form is human readable in the Japanese environment. 877338032Speter Based on a fix from (surprise!) Motonori Nakamura. 877438032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 877538032Speter messages to that host; these are most frequently associated 877638032Speter with addresses rather than the host, with the exception of 877738032Speter 421 (service shutting down). The effect was to cause queues 877838032Speter to sometimes take an excessive time to flush. Reported by 877938032Speter Robert Sargent of Southern Geographics Technologies and 878038032Speter Eric Prestemon of American University. 878138032Speter Add Nice=N mailer option to set the niceness at which a mailer will 878238032Speter run. This is actually a relative niceness (that is, an 878338032Speter increment on the background value). 878438032Speter Log queue runs that are skipped due to high loads. They are logged 878538032Speter at LOG_INFO priority iff the log level is > 8. Contributed 878638032Speter by Bruce Nagel of Data General. 878738032Speter Allow the error mailer to accept a DSN-style error status code 878838032Speter instead of an sysexits status code in the host part. 878938032Speter Anything with a dot will be interpreted as a DSN-style code. 879038032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 879138032Speter to encode characters that might be munged by an EBCDIC system 879238032Speter in addition to the set required by RFC 1521. The additional 879338032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 879438032Speter (Think of "IBM 360" as the mnemonic for this flag.) 879538032Speter Change check for mailing to files to look for a pathname of [FILE] 879638032Speter rather than looking for the mailer named *file*. The mapping 879738032Speter of leading slashes still goes to the *file* mailer. This 879838032Speter allows you to implement the *file* mailer as a separate 879938032Speter program, for example, to insert a Content-Length: header 880038032Speter or do special security policy. However, note that the usual 880138032Speter initial checking for the file permissions is still done, and 880238032Speter the program in question needs to be very careful about how 880338032Speter it does the file write to avoid security problems. 880438032Speter Be able to read ~root/.forward even if the path isn't accessible to 880538032Speter regular users. This is disrecommended because sendmail 880638032Speter sometimes does not run as root (e.g., when an unsafe option 880738032Speter is specified on the command line), but should otherwise be 880838032Speter safe because .forward files must be owned by the user for 880938032Speter whom mail is being forwarded, and cannot be a symbolic link. 881038032Speter Suggested by Forrest Aldrich of Wang Laboratories. 881138032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 881238032Speter file. This is used for canonifying hostnames when the 881338032Speter service type is "files". 881438032Speter Implement programs on F (read class from file) line. The syntax is 881538032Speter Fc|/path/to/program to read the output from the program 881638032Speter into class "c". 881738032Speter Probe the network interfaces to find alternate names for this 881838032Speter host. Requires the SIOCGIFCONF ioctl call. Code 881938032Speter contributed by SunSoft. 882038032Speter Add "E" configuration line to set or propagate environment 882138032Speter variables into children. "E<envar>" will propagate 882238032Speter the named variable from the environment when sendmail 882338032Speter was invoked into any children it calls; "E<envar>=<value>" 882438032Speter sets the named variable to the indicated value. Any 882538032Speter variables not explicitly named will not be in the child 882638032Speter environment. However, sendmail still forces an 882738032Speter "AGENT=sendmail" environment variable, in part to enforce 882838032Speter at least one environment variable, since many programs and 882938032Speter libraries die horribly if this is not guaranteed. 883038032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 883138032Speter alias databases -- new algorithm looks for the substring 883238032Speter "/yp/" in the file name. This is more portable and involves 883338032Speter less overhead. Suggested by Motonori Nakamura. 883438032Speter Dynamically allocate the queue work list so that you don't lose 883538032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 883638032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 883738032Speter should not need to be changed) and the MaxQueueRunSize option, 883838032Speter which is the absolute maximum number of jobs that will ever 883938032Speter be handled in a single queue run. Based on code contributed 884038032Speter by Brian Coan of the Institute for Global Communications. 884138032Speter Log message when a message is dropped because it exceeds the maximum 884238032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 884338032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 884438032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 884538032Speter of Mark G. Thomas Consulting. 884638032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 884738032Speter OS-dependent defines). The old semantic of -d0.1 to not 884838032Speter run the daemon in background has been moved to -d99.100, 884938032Speter and the old 52.5 flag (to avoid disconnect() from closing 885038032Speter all output files) has been moved to 52.100. This makes 885138032Speter things more consistent (flags below .100 don't change 885238032Speter semantics) and separates out the backgrounding so that 885338032Speter it doesn't happen automatically on other unrelated debugging 885438032Speter flags. 885538032Speter If -t is used but no addresses are found in the header, give an 885638032Speter error message rather than just doing nothing. Fix from 885738032Speter Motonori Nakamura. 885838032Speter On systems (like SunOS) where the effective gid is not necessarily 885938032Speter included in the group list returned by getgroups(), the 886038032Speter `restrictmailq' option could sometimes cause an authorized 886138032Speter user to not be able to use `mailq'. Fix from Charles Hannum 886238032Speter of MIT. 886338032Speter Allow symbolic service names for [IPC] mailers. Suggested by 886438032Speter Gerry Magennis of Logica International. 886538032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 886638032Speter when running DNS. For example, if the name FTP.Foo.ORG is 886738032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 886838032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 886938032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 887038032Speter This is technically illegal under RFC 822 and 1123, but the 887138032Speter IETF is moving toward legalizing it. Note that turning on 887238032Speter this option is not sufficient to guarantee that a downstream 887338032Speter neighbor won't rewrite the address for you. 887438032Speter Add "-m" flag to makesendmail script -- this tells you what object 887538032Speter directory and Makefile it will use, but doesn't actually do 887638032Speter the make. 887738032Speter Do some additional checking on the contents of the qf file to try 887838032Speter to detect attacks against the qf file. In particular, 887938032Speter abort on any line beginning "From ", and add an "end of 888038032Speter file" line -- any data after that line is prohibited. 888138032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 888238032Speter choices. This can be overridden in the Makefile by using 888338032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 888438032Speter (to the extent that we know it) or by defining 888538032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 888638032Speter sendmail 8 to have more consistent installation instructions. 888738032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 888838032Speter of Sun Microsystems. 888938032Speter Improved symbol table hash function from Eric Wassenaar. This one 889038032Speter is at least 50% faster. 889138032Speter Fix problem that didn't notice that timeout on file open was a 889238032Speter transient error. Fix from Larry Parmelee of Cornell 889338032Speter University. 889438032Speter Allow comments (lines beginning with a `#') in files read for 889538032Speter classes. Suggested by Motonori Nakamura. 889638032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 889738032Speter of dropping out entirely. This makes testing some of the 889838032Speter name server lookups easier to deal with when there are 889938032Speter hung servers. From Motonori Nakamura. 890038032Speter Add new ${opMode} macro that is set to the current operation mode 890138032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 890238032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 890338032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 890438032Speter Kind of like queue-only mode (Odq) except it tries to avoid 890538032Speter any external service requests; for dial-on-demand hosts that 890638032Speter want to minimize DNS lookups when mail is being queued. For 890738032Speter this to work you will also have to make sure that gethostbyname 890838032Speter of your local host name does not do a DNS lookup. 890938032Speter Improved handling of "out of space" conditions from John Myers of 891038032Speter Carnegie Mellon. 891138032Speter Improved security for mailing to files on systems that have fchmod(2) 891238032Speter support. 891338032Speter Improve "cannot send message for N days" message -- now says "could 891438032Speter not send for past N days". Suggested by Tom Moore of AT&T 891538032Speter Global Information Solutions. 891638032Speter Less misleading Subject: line on messages sent to postmaster only. 891738032Speter From Motonori Nakamura. 891838032Speter Avoid duplicate error messages on bad command line flags.

Problem reported by David 892638032Speter James of British Telecom. 892738032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 892838032Speter from Alexander Dupuy of System Management ARTS. 892938032Speter Delete duplicates in MX lists -- believe it or not, there are sites 893038032Speter that list the same host twice in an MX list. This deletion 893138032Speter only works on adjacent preferences, so an MX list that 893238032Speter had A=5, B=10, A=15 would leave both As, but one that had 893338032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 893438032Speter just in case there is something weird I haven't thought of. 893538032Speter Suggested by Barry Shein of Software Tool & Die. 893638032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 903138032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 903238032Speter University of Brno (Czech Republic). 903338032Speter KSR OS 1.2.2 support from Todd Miller of the University 903438032Speter of Colorado. 903538032Speter UX4800 support from Kazuhisa Shimizu of NEC. 903638032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 903738032Speter in type ``btree'' maps. The semantics of this are undefined 903838032Speter for regular maps, but it can be useful for the user database. 903938032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 904038032Speter lookups while the rebuild is going on. There is a race 904138032Speter condition between the open(... O_TRUNC ...) and the lock 904238032Speter on the file, but it should be quite small. 904338032Speter SMRSH: sendmail restricted shell added to the release. This can 904438032Speter be used as an alternative to /bin/sh for the "prog" mailer, 904538032Speter giving the local administrator more control over what 904638032Speter programs can be run from sendmail. 904738032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 904838032Speter part of the release proper, and isn't fully supported; in 904938032Speter particular, it does not run on System V based systems and 905038032Speter never will. 905138032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 905238032Speter to allow rmail to compile on systems that don't have 905338032Speter function prototypes and systems that don't have snprintf. 905438032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 905538032Speter lists by transaction delay times so that addresses that 905638032Speter respond quickly get sent first. This is to prevent very 905738032Speter sluggish servers from delaying other peoples' mail. 905838032Speter Contributed by Tony Sanders of BSDI. 905938032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 906038032Speter of BSDI. This has a lot of comments to help people out. 906138032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 906238032Speter put this on the m4 command line. On GNU m4 (which 906338032Speter supports the __file__ primitive) you can run m4 in an 906438032Speter arbitrary directory -- use either: 906538032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 906638032Speter or 906738032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 906838032Speter On other versions of m4 that don't support __file__, you 906938032Speter can use: 907038032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 907138032Speter (Note the trailing slash on the _CF_DIR_ definition.) 907238032Speter Old versions of m4 will default to _CF_DIR_=.. for back 907338032Speter compatibility. 907438032Speter CONFIG: fix mail from <> so it will properly convert to 907538032Speter MAILER-DAEMON on local addresses. 907638032Speter CONFIG: fix code that was supposed to catch colons in host 907738032Speter names. Problem noted by John Gardiner Myers of CMU. 907838032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 907938032Speter From Paul Riddle of the University of Maryland, Baltimore 908038032Speter County. 908138032Speter CONFIG: Catch and reject "." as a host address. 908238032Speter CONFIG: Generalize domaintable to look up all domains, not 908338032Speter just unqualified ones. 908438032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 908538032Speter was never used and didn't work anyway. 908638032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 908738032Speter and d on all mailers in the UUCP class. 908838032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 908938032Speter look for an alias for "user+detail", then for "user+*", and 909038032Speter finally for "user". This is intended for forwarding mail 909138032Speter for system aliases such as root and postmaster to a 909238032Speter centralized hub. 909338032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 909438032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 909538032Speter The F=8 flag is also set on the "relay" mailer, since 909638032Speter this is expected to be another sendmail. 909738032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 909838032Speter the name of the UUCP_RELAY -- in some cases, this is the 909938032Speter wrong value (e.g., when we have local UUCP connections), 910038032Speter and this can create unreplyable addresses. From Chip 910138032Speter Rosenthal of Unicom. 910238032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 910364562Sgshapiro Received: header inserted into all messages. Suggested by 910438032Speter Gary Mills of the University of Manitoba. 910538032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 910643730Speter to get the old behavior. I did this upon observing 910738032Speter that almost everyone needed this feature, and that the 910838032Speter concept I was trying to make happen didn't work with 910938032Speter some user agents anyway. FEATURE(notsticky) still works, 911038032Speter but it is a no-op. 911138032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 911238032Speter names are sent, rather than immediately diagnosing them 911338032Speter as User Unknown. 911438032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 911538032Speter and RELAY_MAILER_ARGS to set the arguments for the 911638032Speter indicated mailers. All default to "IPC $h". Patch from 911738032Speter Larry Parmelee of Cornell University. 911838032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 911938032Speter on the client side" and F=P to get an appropriate 912038032Speter return-path. From Kimmo Suominen. 912138032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 912238032Speter as the local mailer. For addresses of the form "user+detail" 912338032Speter the "detail" part is passed to procmail via the -a flag. 912438032Speter Contributed by Kimmo Suominen. 912538032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 912638032Speter use from mailertables. This lets you execute arbitrary 912738032Speter procmail scripts. Contributed by Kimmo Suominen. 912838032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 912938032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 913038032Speter Paul Southworth of CICNet Systems Support. 913138032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 913238032Speter This causes the null return path to be rewritten as 913338032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 913438032Speter From Michael Hohmuth of Technische Universitat Dresden. 913538032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 913638032Speter list us as the best possible MX record to be treated as 913738032Speter though they were local (essentially, assume that they 913838032Speter are included in $=w). This can cause additional DNS 913938032Speter traffic, but is easier to administer if this fits your 914038032Speter local model. It does not work reliably if there are 914138032Speter multiple hosts that share the best MX preference. 914238032Speter Code contributed by John Oleynick of Rutgers. 914338032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 914438032Speter SHell) instead of /bin/sh as the program used for delivery 914538032Speter to programs. If an argument is included, it is used as 914638032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 914738032Speter assumed. 914838032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 914938032Speter size of messages to the local and procmail mailers 915038032Speter respectively. Contributed by Brad Knowles of the Defense 915138032Speter Information Systems Agency. 915238032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 915338032Speter (just like text outside of angle brackets) in order to 915438032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 915538032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 915638032Speter any real systems any more) and tweak the DOMAIN macro 915738032Speter so that it is less likely that users will accidentally use 915838032Speter the Berkeley defaults. Also, create some generic files 915938032Speter that really can be used in the real world. 916038032Speter CONFIG: Add new configuration macros to set character sets for 916138032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 916238032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 916338032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 916438032Speter The old name will still be accepted for a while at least. 916538032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 916638032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 916738032Speter As with all relays, it can be ``mailer:hostname''. Suggested 916838032Speter by Scott Hutton. 916938032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 917038032Speter by Barb Dijker of Labyrinth Computer Services. 917138032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 917238032Speter performance for large alias files, and this confused many 917338032Speter people. 917438032Speter CONFIG: Add confCF_VERSION to append local information to the 917538032Speter configuration version number displayed during SMTP startup. 917638032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 917738032Speter would only work when locally addressed. Fix from 917838032Speter Edvard Tuinder of Cistron Internet Services. 917938032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 918043730Speter "n" (CheckAliases) is set when rebuilding alias database. 918138032Speter Based on code contributed by Claude Marinier. 918238032Speter CONFIG: Allow mailertable to have values of the form 918338032Speter ``error:code message''. The ``code'' is a status code 918438032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 918538032Speter Contributed by David James <dwj@agw.bt.co.uk>. 918638032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 918738032Speter sender domains that will be replaced with the masquerade name. 918838032Speter These domains will not be treated as local, but if mail passes 918938032Speter through with sender addresses in those domains they will be 919038032Speter replaced by the masquerade name. These can also be specified 919138032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 919238032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 919338032Speter as well as the header. Substantial improvements to this 919438032Speter code were contributed by Per Hedeland. 919538032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 919638032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 919738032Speter by Kimmo Suominen. 919838032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 919938032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 920038032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 920138032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 920238032Speter UUCP addressing.

This caused UnixWare 934538032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 934638032Speter Novell Labs Europe. 934738032Speter Fix problem with static linking of local getopt routine when 934838032Speter using GNU's ld command. Fix from John Kennedy of 934938032Speter Cal State Chico. 935038032Speter It was possible to turn off privacy flags. Problem noted by 935138032Speter *Hobbit*. 935238032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 935338032Speter and Liudvikas Bukys. 935438032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 935538032Speter from Spider Boardman. 935638032Speter CONFIG: No changes (version number only, to keep it in sync 935738032Speter with the binaries). 935838032Speter 935964562Sgshapiro8.6.10/8.6.10 1995/02/10 936038032Speter SECURITY: Diagnose bogus values to some command line flags that 936138032Speter could allow trash to get into headers and qf files. 936238032Speter Validate the name of the user returned by the IDENT protocol. 936338032Speter Some systems that really dislike IDENT send intentionally 936438032Speter bogus information. Problem pointed out by Michael Bushnell 936538032Speter of the Free Software Foundation. Has some security 936638032Speter implications. 936738032Speter Fix a problem causing error messages about DNS problems when 936838032Speter the host name contained a percent sign to act oddly 936938032Speter because it was passed as a printf-style format string. 937038032Speter In some cases this could cause core dumps. 937138032Speter Avoid possible buffer overrun in returntosender() if error 937238032Speter message is quite long. From Fletcher Mattox of the 937338032Speter University of Texas. 937438032Speter Fix a problem that would silently drop "too many hops" error 937538032Speter messages if and only if you were sending to an alias. 937638032Speter From Jon Giltner of the University of Colorado and 937738032Speter Dan Harton of Oak Ridge National Laboratory. 937838032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 937938032Speter set and e->e_message was null. Fix from Bruce Nagel of 938038032Speter Data General. 938138032Speter Fix problem that can still cause df files to be left around 938238032Speter after "hop count exceeded" messages. Fix from Andrew 938338032Speter Chang and Shau-Ping Lo of SunSoft. 938438032Speter Fix a problem that can cause buffer overflows on very long 938538032Speter user names (as might occur if you piped to a program 938638032Speter with a lot of arguments). 938738032Speter Avoid returning an error and re-queueing if the host signature 938838032Speter is null; this can occur on addresses like ``user@.''. 938938032Speter Problem noted by Wesley Craig and the University of 939038032Speter Michigan. 939138032Speter Avoid possible calls to malloc(0) if MCI caching is turned 939238032Speter off. Bug fix from Pierre David of the Laboratoire 939338032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 939438032Speter Universite de Versailles - St Quentin, and Jacky 939538032Speter Thibault. 939638032Speter Make a local copy of the line being sent via senttolist() -- in 939738032Speter some cases, buffers could get trashed by map lookups 939838032Speter causing it to do unexpected things. This also simplifies 939938032Speter some of the map code. 940038032Speter CONFIG: No changes (version number only, to keep it in sync 940138032Speter with the binaries). 940238032Speter 940364562Sgshapiro8.6.9/8.6.9 1994/04/19 940438032Speter Do all mail delivery completely disconnected from any terminal. 940538032Speter This provides consistency with daemon delivery and 940638032Speter may have some security implications. 940738032Speter Make sure that malloc doesn't get called with zero size, 940838032Speter since that fails on some systems. Reported by Ed 940938032Speter Hill of the University of Iowa. 941038032Speter Fix multi-line values for $e (SMTP greeting message). Reported 941138032Speter by Mike O'Connor of Ford Motor Company. 941238032Speter Avoid syserr if no NIS domain name is defined, but the map it 941338032Speter is trying to open is optional. From Win Bent of USC. 941438032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 941538032Speter Hesiod support for UDB from Todd Miller of the University of 941638032Speter Colorado. Use "hesiod" as the service name in the U 941738032Speter option. 941838032Speter Fix a problem that failed to set the "authentic" host name (that 941938032Speter is, the one derived from the socket info) if you called 942038032Speter sendmail -bs from inetd. Based on code contributed by 942138032Speter Todd Miller (this problem was also reported by Guy Helmer 942238032Speter of Dakota State University). This also fixes a related 942338032Speter problem reported by Liudvikas Bukys of the University of 942438032Speter Rochester. 942538032Speter Parameterize "nroff -h" in all the Makefiles so people with 942638032Speter variant versions can use them easily. Suggested by 942738032Speter Peter Collinson of Hillside Systems. 942838032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 942938032Speter spaces between parameters instead of one. Reported by 943038032Speter Valdis Kletnieks of Virginia Tech. 943138032Speter Reduce the number of system calls during message collection by 943238032Speter using global timeouts around the collect() loop. This 943338032Speter code was contributed by Eric Wassenaar. 943438032Speter If the initial hostname name gathering results in a name 943538032Speter without a dot (usually caused by NIS misconfiguration) 943638032Speter and BIND is compiled in, directly access DNS to get 943738032Speter the canonical name. This should make life easier for 943838032Speter Solaris systems. If it still can't be resolved, and 943938032Speter if the name server is listed as "required", try again 944038032Speter in 30 seconds. If that also fails, exit immediately to 944138032Speter avoid bogus "config error: mail loops back to myself" 944238032Speter messages. 944338032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 944438032Speter message to explain how much space was available and 944538032Speter sound a bit less threatening. Suggested by Stan Janet 944638032Speter of the National Institute of Standards and Technology. 944738032Speter If mail is delivered to an alias that has an owner, deliver any 944838032Speter requested return-receipt immediately, and strip the 944938032Speter Return-Receipt-To: header from the subsequent message. 945038032Speter This prevents a certain class of denial of service 945138032Speter attack, arguably gives more reasonable semantics, and 945238032Speter moves things more towards what will probably become a 945338032Speter network standard. Suggested by Christopher Davis of 945438032Speter Kapor Enterprises. 945538032Speter Add a "noreceipts" privacy flag to turn off all return receipts 945638032Speter without recompiling. 945738032Speter Avoid printing ESMTP parameters as part of the error message 945838032Speter if there are errors during parsing. This change is 945938032Speter purely cosmetic. 946038032Speter Avoid sending out error messages during the collect phase of 946138032Speter SMTP; there is an MVS mailer from UCLA that gets 946238032Speter confused by this. Of course, I think it's their bug.... 946338032Speter Check for the $j macro getting undefined, losing a dot, or getting 946438032Speter lost from $=w in the daemon before accepting a connection; 946538032Speter if it is, it dumps state, prints a LOG_ALERT message, 946638032Speter and drops core for debugging. This is an attempt to 946738032Speter track down a bug that I thought was long since gone. 946838032Speter If you see this, please forward the log fragment to 946938032Speter sendmail@sendmail.ORG. 947038032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 947138032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 947238032Speter Wolfhugel. 947338032Speter Instead of trying to truncate the listen queue for the server 947438032Speter SMTP port when the load average is too high, just close 947538032Speter the port completely and reopen it later as needed. 947638032Speter This ensures that the other end gets a quick "connection 947738032Speter refused" response, and that the connection can be 947838032Speter recovered later. In particular, some socket emulations 947938032Speter seem to get confused if you tweak the listen queue 948038032Speter size around and can never start listening to connections 948138032Speter again. The down side is that someone could start up 948238032Speter another daemon process in the interim, so you could 948338032Speter have multiple daemons all not listening to connections; 948438032Speter this could in turn cause the sendmail.pid file to be 948538032Speter incorrect. A better approach might be to accept the 948638032Speter connection and give a 421 code, but that could break 948743730Speter other mailers in mysterious ways and have paging behavior 948838032Speter implications. 948938032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 949038032Speter set debugging on the wrong socket. From Eric Wassenaar. 949138032Speter When creating a df* temporary file, be sure you truncate any 949238032Speter existing data in the file -- otherwise system crashes 949338032Speter and the like could result in extra data being sent. 949438032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 949538032Speter doc directory. This includes some additional 949638032Speter information. 949738032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 949838032Speter of recipient envelope addresses. This should have been 949938032Speter handled by the $&h trick, but broke if people were 950038032Speter mixing domainized and UUCP addresses. They should 950138032Speter probably have converted all the way over to uucp-uudom 950238032Speter instead of uucp-{new,old}, but the failure mode was to 950338032Speter loop the mail, which was bad news. 950438032Speter Portability fixes: 950538032Speter Newer BSDI systems (several people). 950638032Speter Older BSDI systems from Christophe Wolfhugel. 950738032Speter Intergraph CLIX, from Paul Southworth of CICNet. 950838032Speter UnixWare, from Evan Champion. 950938032Speter NetBSD from Adam Glass. 951038032Speter Solaris from Quentin Campbell of the University of 951138032Speter Newcastle upon Tyne. 951238032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 951338032Speter Corporation. 951438032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 951538032Speter SunOS (it has setsid() and setvbuf() calls) from 951638032Speter Jonathan Kamens of OpenVision Technologies. 951738032Speter HP-UX from Tor Lillqvist. 951838032Speter New Files: 951938032Speter src/Makefile.CLIX 952038032Speter src/Makefile.NCR3000 952138032Speter doc/changes/Makefile 952238032Speter doc/changes/changes.me 952338032Speter doc/changes/changes.ps 952438032Speter 952564562Sgshapiro8.6.8/8.6.6 1994/03/21 952638032Speter SECURITY: it was possible to read any file as root using the 952738032Speter E (error message) option. Reported by Richard Jones; 952838032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 952938032Speter 953064562Sgshapiro8.6.7/8.6.6 1994/03/14 953138032Speter SECURITY: it was possible to get root access by using weird 953238032Speter values to the -d flag. Thanks to Alain Durand of 953338032Speter INRIA for forwarding me the notice from the bugtraq 953438032Speter list. 953538032Speter 953664562Sgshapiro8.6.6/8.6.6 1994/03/13 953738032Speter SECURITY: the ability to give files away on System V-based 953838032Speter systems proved dangerous -- don't run as the owner 953938032Speter of a :include: file on a system that allows giveaways. 954038032Speter Unfortunately, this also applies to determining a 954138032Speter valid shell. 954238032Speter IMPORTANT: Previous versions weren't expiring old connections 954338032Speter in the connection cache for a long time under some 954438032Speter circumstances. This could result in resource exhaustion, 954538032Speter both at your end and at the other end. This checks the 954638032Speter connections for timeouts much more frequently. From 954738032Speter Doug Anderson of NCSC. 954838032Speter Fix a glitch that snuck in that caused programs to be run as 954938032Speter the sender instead of the recipient if the mail was 955038032Speter from a local user to another local user. From 955138032Speter Motonori Nakamura of Kyoto University. 955238032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 955338032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 955438032Speter Bryan Costales of ICSI. 955538032Speter Change the method used to declare the "statfs" availability; 955638032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 955738032Speter tweaking in conf.c, there is a single #define called 955838032Speter SFS_TYPE which takes on one of six values (SFS_NONE 955938032Speter for no statfs availability, SFS_USTAT for the ustat(2) 956038032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 956138032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 956238032Speter statfs(2) call with the declarations in <sys/vfs.h>, 956338032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 956438032Speter Fix glitch in NetInfo support that could return garbage if 956538032Speter there was no "/locations/sendmail" property. From 956638032Speter David Meyer of the University of Virginia. 956738032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 956838032Speter to allow Linux to turn it off even though it is a 956938032Speter BSD-like system. 957038032Speter Allow setting of "ident" timeout to zero to turn off the ident 957138032Speter protocol entirely. 957238032Speter Make 7-bit stripping local to a connection (instead of to a 957338032Speter mailer); this allows you to specify that SMTP is a 957438032Speter 7-bit channel, but revert to 8-bit should it advertise 957538032Speter that it supports 8BITMIME. You still have to specify 957638032Speter mailer flag 7 to get this stripping at all. 957738032Speter Improve makesendmail script so it handles more cases automatically. 957838032Speter Tighten up restrictions on taking ownership of :include: files 957938032Speter to avoid problems on systems that allow you to give away 958038032Speter files. 958138032Speter Fix a problem that made it impossible to rebuild the alias 958238032Speter file if it was on a read-only file system. From 958338032Speter Harry Edmon of the University of Washington. 958438032Speter Improve MX randomization function. From John Gardiner Myers 958538032Speter of CMU. 958638032Speter Fix a minor glitch causing a bogus message to be printed (used 958738032Speter %s instead of %d in a printf string for the line number) 958838032Speter when a bad queue file was read. From Harry Edmon. 958938032Speter Allow $s to remain NULL on locally generated mail. I'm not 959038032Speter sure this is necessary, but a lot of people have complained 959138032Speter about it, and there is a legitimate question as to whether 959238032Speter "localhost" is legal as an 822-style domain. 959338032Speter Fix a problem with very short line lengths (mailer L= flag) in 959438032Speter headers. This causes a leading space to be added onto 959538032Speter continuation lines (including in the body!), and also 959638032Speter tries to wrap headers containing addresses (From:, To:, 959738032Speter etc) intelligently at the shorter line lengths. Problem 959838032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 959938032Speter Log the real user name when logging syserrs, since these can have 960038032Speter security implications. Suggested by several people. 960138032Speter Fix address logging of cached connections -- it used to always 960238032Speter log the numeric address as zero. This is a somewhat 960338032Speter bogus implementation in that it does an extra system 960438032Speter call, but it should be an inexpensive one. Fix from 960538032Speter Motonori Nakamura. 960638032Speter Tighten up handling of short syslog buffers even more -- there 960738032Speter were cases where the outgoing relay= name was too long 960838032Speter to share a line with delay= and mailer= logging. 960938032Speter Limit the overhead on split envelopes to one open file descriptor 961038032Speter per envelope -- previously the overhead was three 961138032Speter descriptors. This was in response to a problem reported 961238032Speter by P{r (Pell) Emanuelsson. 961338032Speter Fixes to better handle the case of unexpected connection closes; 961438032Speter this redirects the output to the transcript so the info 961538032Speter is not lost. From Eric Wassenaar. 961638032Speter Fix potential string overrun if you macro evaluate a string that 961738032Speter has a naked $ at the end. Problem noted by James Matheson 961838032Speter <jmrm@eng.cam.ac.uk>. 961938032Speter Make default error number on $#error messages 553 (``Requested 962038032Speter action not taken: mailbox name not allowed'') instead of 962138032Speter 501 (``Syntax error in parameters or arguments'') to 962238032Speter avoid bogus "protocol error" messages. 962338032Speter Strip off any existing trailing dot on names during $[ ... $] 962438032Speter lookup. This prevents it from ending up with two dots 962538032Speter on the end of dot terminated names. From Wesley Craig 962638032Speter of the University of Michigan and Bryan Costales of ICSI. 962738032Speter Clean up file class reading so that the debugging information is 962838032Speter more informative. It hadn't been using setclass, so you 962938032Speter didn't see the class items being added. 963038032Speter Avoid core dump if you are running a version of sendmail where 963138032Speter NIS is compiled in, and you specify an NIS map, but 963238032Speter NIS is not running. Fix from John Oleynick of 963338032Speter Rutgers. 963438032Speter Diagnose bizarre case where res_search returns a failure value, 963538032Speter but sets h_errno to a success value. 963638032Speter Make sure that "too many hops" messages are considered important 963738032Speter enough to send an error to the Postmaster (that is, the 963838032Speter address specified in the P option). This fix should 963938032Speter help problems that cause the df file to be left around 964038032Speter sometimes -- unfortunately, I can't seem to reproduce 964138032Speter the problem myself. 964238032Speter Avoid core dump (null pointer reference) on EXPN command; this 964338032Speter only occurred if your log level was set to 10 or higher 964438032Speter and the target account was an alias or had a .forward file. 964538032Speter Problem noted by Janne Himanka. 964638032Speter Avoid "denial of service" attacks by someone who is flooding your 964738032Speter SMTP port with bad commands by shutting the connection 964838032Speter after 25 bad commands are issued. From Kyle Jones of 964938032Speter UUNET. 965038032Speter Fix core dump on error messages with very long "to" buffers; 965138032Speter fmtmsg overflows the message buffer. Fixed by trimming 965238032Speter the to address to 203 characters. Problem reported by 965338032Speter John Oleynick. 965438032Speter Fix configuration for HASFLOCK -- there were some spots where 965538032Speter a #ifndef was incorrectly #ifdef. Pointed out by 965638032Speter George Baltz of the University of Maryland. 965738032Speter Fix a typo in savemail() that could cause the error message To: 965838032Speter lists to be incorrect in some places. From Motonori 965938032Speter Nakamura. 966038032Speter Fix a glitch that can cause duplicate error messages on split 966138032Speter envelopes where an address on one of the lists has a 966238032Speter name server failure. Fix from Voradesh Yenbut of the 966338032Speter University of Washington. 966438032Speter Fix possible bogus pointer reference on ESMTP parameters that 966538032Speter don't have an ``=value'' part. 966638032Speter CNAME loops caused an error message to be generated, but also 966738032Speter re-queued the message. Changed to just re-queue the 966838032Speter message (it's really hard to just bounce it because 966938032Speter of the weird way the name server works in the presence 967038032Speter of CNAME loops). Problem noted by James M.R.Matheson 967138032Speter of Cambridge University. 967238032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 967338032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 967438032Speter user name. Suggested by Andreas Stolcke of ICSI. 967538032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 967638032Speter override it easily in the Makefile -- that is, you can 967738032Speter turn it off using -DNAMED_BIND=0. 967838032Speter If a gethostbyname(...) of an address with a trailing dot fails, 967938032Speter try it without the trailing dot. This is because if 968038032Speter you have a version of gethostbyname() that falls back 968138032Speter to NIS or the /etc/hosts file it will fail to find 968238032Speter perfectly reasonable names that just don't happen to 968338032Speter be dot terminated in the hosts file. You don't want to 968438032Speter strip the dot first though because we're trying to ensure 968538032Speter that country names that match one of your subdomains get 968638032Speter a chance. 968738032Speter PRALIASES: fix bogus output on non-null-terminated strings. 968838032Speter From Bill Gianopoulos of Raytheon. 968938032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 969038032Speter This was in code intended to only catch the self-literal 969138032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 969238032Speter IP address), but the code was broken. However, it will 969338032Speter still do this if $M is defined; this is necessary to 969438032Speter get client configurations to work (sigh). Note that this 969538032Speter means that $M overrides :mailname entries in the user 969638032Speter database! Problem noted by Paul Southworth. 969738032Speter CONFIG: Fix definition of Solaris help file location. From 969838032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 969938032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 970038032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 970138032Speter and USENET_MAILER_MAX to tweak the maximum message 970238032Speter size for various mailers. 970338032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 970438032Speter instead of assuming that it is "inews" for consistency 970538032Speter with other mailers. From Michael Corrigan of UC San Diego. 970638032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 970738032Speter qualify the address in the SMTP envelope as user@{relay|hub} 970838032Speter instead of user@$j. From Bill Wisner of The Well. 970938032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 971038032Speter CONFIG: Don't turn off case mapping of user names in the local 971138032Speter mailer for IRIX. This was different than most every other 971238032Speter system. 971338032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 971438032Speter envelope. Noted by Thierry Besancon 971538032Speter <besancon@excalibur.ens.fr>. 971638032Speter CONFIG: Don't include -z by default on uux line -- most systems 971738032Speter don't want it set by default. Pointed out by Philippe 971838032Speter Michel of Thomson CSF. 971938032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 972038032Speter host name was foo.bar.ray.com and you matched against 972138032Speter ".ray.com", the old implementation bound %1 to "bar" 972238032Speter instead of "foo.bar". Also, allow "." in the mailertable 972338032Speter to match anything -- essentially, take over SMART_HOST. 972438032Speter This also moves matching of explicit local host names 972538032Speter before the mailertable so they don't have to be special 972638032Speter cased in the mailertable data. Reported by Bill 972738032Speter Gianopoulos of Raytheon; the fix for the %1 binding 972838032Speter problem was contributed by Nicholas Comanos of the 972938032Speter University of Sydney. 973038032Speter CONFIG: Don't include "root" in class $=L (users to deliver 973138032Speter locally, even if a hub or relay exists) by default. 973238032Speter This is because of the known bug where definition of 973338032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 973438032Speter both and deliver into the local mailbox. 973538032Speter CONFIG: Move up bitdomain and uudomain handling so that they 973638032Speter are done before .UUCP class matching; uudomain was 973738032Speter reported as ineffective before. This also frees up 973838032Speter diversion 8 for future use. Problem reported by Kimmo 973938032Speter Suominen. 974038032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 974138032Speter into host names. As pointed out by Jonathan Kamens, 974238032Speter these are often used because either the forward or reverse 974338032Speter mapping is broken; this translation makes it broken again. 974438032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 974538032Speter Suominen. 974638032Speter Portability fixes: 974738032Speter Unicos from David L.

From 977138032Speter Bob Campbell at U.C. Berkeley. 977238032Speter Security fix: group ids were not completely set when programs 977338032Speter were invoked. This caused programs to have group 977438032Speter permissions they should not have had (usually group 977538032Speter daemon instead of their own group). In particular, 977638032Speter Perl scripts would refuse to run. 977738032Speter Security: check to make sure files that are written are not 977838032Speter symbolic links (at least under some circumstances). 977938032Speter Although this does not respond to a specific known 978038032Speter attack, it's just a good idea. Suggested by 978138032Speter Christian Wettergren. 978238032Speter Security fix: if a user had an NFS mounted home directory on 978338032Speter a system with a restricted shell listed in their 978438032Speter /etc/passwd entry, they could still execute any 978538032Speter program by putting that in their .forward file. 978638032Speter This fix prevents that by insisting that their shell 978738032Speter appear in /etc/shells before allowing a .forward to 978838032Speter execute a program or write a file. You can disable 978938032Speter this by putting "*" in /etc/shells. It also won't 979038032Speter permit world-writable :include: files to reference 979138032Speter programs or files (there's no way to disable this). 979243730Speter These behaviors are only one level deep -- for 979338032Speter example, it is legal for a world-writable :include: 979438032Speter file to reference an alias that writes a file, on 979538032Speter the assumption that the alias file is well controlled. 979638032Speter Security fix: root was not treated suspiciously enough when 979738032Speter looking into subdirectories. This would potentially 979838032Speter allow a cracker to examine files that were publicly 979938032Speter readable but in a non-publicly searchable directory. 980038032Speter Fix a problem that causes an error on QUIT on a cached 980138032Speter connection to create problems on the current job. 980238032Speter These are typically unrelated, so errors occur in 980338032Speter the wrong place. 980438032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 980538032Speter runs more responsive to load average, and fixes a 980638032Speter problem that ignored the load average in locally 980738032Speter generated mail. From Eric Wassenaar. 980838032Speter Fix possible core dump on aliases with null LHS. From 980938032Speter John Orthoefer of BB&N. 981038032Speter Revert to using flock() whenever possible -- there are just 981138032Speter too many bugs in fcntl() locking, particularly over 981238032Speter NFS, that cause sendmail to fail in perverse ways. 981338032Speter Fix a bug that causes the connection cache to get confused 981438032Speter when sending error messages. This resulted in 981538032Speter "unexpected close" messages. It should fix itself 981638032Speter on the following queue run. Problem noted by 981738032Speter Liudvikas Bukys of the University of Rochester. 981838032Speter Include $k in $=k as documented in the Install & Op Guide. 981938032Speter This seems odd, but it was documented.... From 982038032Speter Michael Corrigan of UCSD. 982138032Speter Fix problem that caused :include:s from alias files to be 982238032Speter forced to be owned by root instead of daemon 982338032Speter (actually DefUid). From Tim Irvin. 982438032Speter Diagnose unrecognized I option values -- from Mortin Forssen 982538032Speter of the Chalmers University of Technology. 982638032Speter Make "error" mailer work consistently when there is no error 982738032Speter code associated with it -- previously it returned OK 982838032Speter even though there was a real problem. Now it assumes 982938032Speter EX_UNAVAILABLE. 983038032Speter Fix bug that caused the last header line of messages that had 983138032Speter no body and which were terminated with EOF instead of 983238032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 983338032Speter Fix core dump on SMTP mail to programs that failed -- it tried 983438032Speter to go to a "next MX host" when none existed, causing 983538032Speter a core dump. From der Mouse at McGill University. 983638032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 983738032Speter this makes it easier to turn it off (using 983838032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 983938032Speter Fix YP_MASTER_NAME store to use the unupdated result of 984038032Speter gethostname() (instead of myhostname(), which tries 984138032Speter to fully qualify the name) to be consistent with 984238032Speter SunOS. If your hostname is unqualified, this fixes 984338032Speter transfers to slave servers. Bug noted by Keith 984438032Speter McMillan of Ameritech Services, Inc. 984538032Speter Fix Ultrix problem: gethostbyname() can return a very large 984638032Speter (> 500) h_length field, which causes the sockaddr 984738032Speter to be trashed. Use the size of the sockaddr instead. 984838032Speter Fix from Bob Manson of Ohio State. 984938032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 985038032Speter defined -- this confuses gethostbyname on hosts 985138032Speter file lookups, which doesn't understand the trailing 985238032Speter dot convention. 985338032Speter Log SMTP server subprocesses that die with a signal instead 985438032Speter of from a clean exit. 985538032Speter If you don't have option "I" set, don't assume that a DNS 985638032Speter "host unknown" message is authoritative -- it 985738032Speter might still be found in /etc/hosts. 985838032Speter Fix a problem that would cause Deferred: messages to be sent 985938032Speter as the subject of an error message, even though the 986038032Speter actual cause of a message was more severe than that. 986138032Speter Problem noted by Chris Seabrook of OSSI. 986238032Speter Fix race condition in DBM alias file locking. From Kyle 986338032Speter Jones of UUNET. 986438032Speter Limit delivery syslog line length to avoid bugs in some 986538032Speter versions of syslog(3). This adds a new compile time 986638032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 986738032Speter University, which is in turn derived from IDA. 986838032Speter Fix quotes inside of comments in addresses -- previously 986938032Speter it insisted that they be balanced, but the 822 spec 987038032Speter says that they should be ignored. 987138032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 987238032Speter debugging). This also evaluates ruleset 89, if set 987338032Speter (with the null input), and logs the result. This 987438032Speter should be used sparingly, since the rewrite process 987538032Speter is not reentrant. 987638032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 987738032Speter documented in the Bat Book. 987838032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 987938032Speter return an error message and did not requeue the message. 988038032Speter Fix based on code from Roland Dirlewanger of 988138032Speter Reseau Regional Aquarel, Bordeaux, France. 988238032Speter Fix a problem that caused a seg fault if you got a 421 error 988338032Speter code during some parts of connection initialization. 988438032Speter I've only seen this when talking to buggy mailers on 988538032Speter the other end, but it shouldn't give a seg fault in 988638032Speter any case. From Amir Plivatsky. 988738032Speter Fix core dump caused by a ruleset call that returns null. 988838032Speter Fix from Bryan Costales of ICSI. 988938032Speter Full-Name: field was being ignored.

Noted by William C Fenner of 992838032Speter the NRL Connection Machine Facility. 992938032Speter Fix a problem that could cause a core dump if the input sequence 993038032Speter had (or somehow acquired) a \231 character. 993138032Speter Make sure that route-addrs always have <angle brackets> around 993238032Speter them in non-SMTP envelopes (SMTP envelopes already do 993338032Speter this properly). 993438032Speter Avoid weird headers on unbalanced punctuation of the form: 993538032Speter ``Joe User <user)'' -- this caused reference to the 993638032Speter null macro. Fix from Rick McCarty of IO.COM. 993738032Speter Fix a problem that caused an alias "user: user@local.host" to 993838032Speter not have the QNOTREMOTE bit set; this caused configs 993938032Speter to act as if FEATURE(notsticky) was defined even when 994038032Speter it was not. The effect of the problem was to make it 994138032Speter very hard to to set up satellite sites that had a few 994238032Speter local accounts, with everything else forwarded to a 994338032Speter corporate hub. Reported by Detlef Drewanz of the 994438032Speter University of Rostock and Mark Frost of NCD. 994538032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 994638032Speter addresses. This is more efficient (fewer name server 994738032Speter calls) and fixes certain unusual configurations, such 994838032Speter as those that have ruleset 4 do something that is 994938032Speter non-idempotent unless a mailer-specific ruleset did 995038032Speter something else.

Briefly, if you are sending to host 1001938032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 1002038032Speter "foo!baz" remains "foo!baz", and anything else has 1002138032Speter the local name prepended. 1002238032Speter CONFIG: portability fixes for HP-UX. 1002338032Speter DOC: several minor problems fixed in the Install & Op Guide. 1002438032Speter MAKEMAP: fix core dump problem on lines that are too long or 1002538032Speter which lack newline. From Mark Delany. 1002638032Speter MAILSTATS: print sums of columns (total messages & kbytes 1002738032Speter in and out of the system). From Tom Ferrin of UC 1002838032Speter San Francisco Computer Graphics Lab. 1002938032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 1003038032Speter On HP-UX, /etc/sendmail.cf has been moved to 1003138032Speter /usr/lib/sendmail.cf to match HP sendmail. 1003238032Speter Permissions have been tightened up on world-writable 1003338032Speter :include: files and accounts that have shells 1003438032Speter that are not listed in /etc/shells. This may 1003538032Speter cause some .forward files that have worked 1003638032Speter before to start failing. 1003738032Speter SIGUSR1 dumps some state to the log. 1003838032Speter NEW FILES: 1003938032Speter src/Makefile.DGUX 1004038032Speter src/Makefile.Dynix 1004138032Speter src/Makefile.FreeBSD 1004238032Speter src/Makefile.Mach386 1004338032Speter src/Makefile.NetBSD 1004438032Speter src/Makefile.RISCos 1004538032Speter src/Makefile.SCO 1004638032Speter src/Makefile.SVR4 1004738032Speter src/Makefile.Titan 1004838032Speter cf/mailer/pop.m4 1004938032Speter cf/ostype/bsdi1.0.m4 1005038032Speter cf/ostype/dgux.m4 1005138032Speter cf/ostype/dynix3.2.m4 1005238032Speter cf/ostype/sco3.2.m4 1005338032Speter makemap/Makefile.dist 1005438032Speter praliases/Makefile.dist 1005538032Speter 1005664562Sgshapiro8.6.4/8.6.4 1993/10/31 1005738032Speter Repair core-dump problem (write to read-only memory segment) 1005838032Speter if you fall back to the return-to-Postmaster case in 1005938032Speter savemail. Problem reported by Richard Liu. 1006038032Speter Immediately diagnose bogus sender addresses in SMTP. This 1006138032Speter makes quite certain that crackers can't use this 1006238032Speter class of attack. 1006338032Speter Reliability Fix: check return value from fclose() and fsync() 1006438032Speter in a few critical places. 1006538032Speter Minor problem in initsys() that reversed a condition for 1006638032Speter redirecting the output channel on queue runs. It's 1006738032Speter not clear this code even does anything. From Eric 1006838032Speter Wassenaar of the Dutch National Institute for Nuclear 1006938032Speter and High-Energy Physics. 1007038032Speter Fix some problems that caused queue runs to do "too much work", 1007138032Speter such as double-reading the Errors-To: header. From 1007238032Speter Eric Wassenaar. 1007338032Speter Error messages on writing the temporary file (including the 1007438032Speter data file) were getting suppressed in SMTP -- this 1007538032Speter fix causes them to be properly reported. From Eric 1007638032Speter Wassenaar. 1007738032Speter Some changes to support AF_UNIX sockets -- this will only 1007838032Speter really become relevant in the next release, but some 1007938032Speter people need it for local patches. From Michael 1008038032Speter Corrigan of UC San Diego. 1008138032Speter Use dynamically allocated memory (instead of static buffers) 1008238032Speter for macros defined in initsys() and settime(); since 1008338032Speter these can have different values depending on which 1008438032Speter envelope they are in. From Eric Wassenaar. 1008538032Speter Improve logging to show ctladdr on to= logging; this tells you 1008638032Speter what uid/gid processes ran as. 1008738032Speter Fix a problem that caused error messages to be discarded if 1008838032Speter the sender address was unparseable for some reason; 1008938032Speter this was supposed to fall back to the "return to 1009038032Speter postmaster" case. 1009138032Speter Improve aliaswait backoff algorithm. 1009238032Speter Portability patches for Linux (8.6.3 required another header 1009338032Speter file) (from Karl London) and SCO UNIX. 1009438032Speter CONFIG: patch prog mailer to not strip host name off of envelope 1009538032Speter addresses (so that it matches local again). From 1009638032Speter Christopher Davis. 1009738032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 1009838032Speter this prevents uux from seeing lines with null names like 1009938032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 1010038032Speter Nakamura of Kyoto University. 1010138032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 1010238032Speter it shouldn't fail miserably. From Motonori Nakamura. 1010338032Speter 1010464562Sgshapiro8.6.2/8.6.2 1993/10/15 1010538032Speter Put a "successful delivery" message in the transcript for 1010638032Speter addresses that get return-receipts. 1010738032Speter Put a prominent "this is only a warning" message in warning 1010838032Speter messages -- some people don't read carefully enough 1010938032Speter and end up sending the message several times. 1011038032Speter Include reason for temporary failure in the "warning" return 1011138032Speter message. Currently, it just says "cannot send for 1011238032Speter four hours". 1011338032Speter Fix the "Original message received" time generated for 1011438032Speter returntosender messages. It was previously listed as 1011538032Speter the current time. Bug reported by Eric Hagberg of 1011638032Speter Cornell University Medical College. 1011738032Speter If there is an error when writing the body of a message, 1011838032Speter don't send the trailing dot and wait for a response 1011938032Speter in sender SMTP, as this could cause the connection to 1012038032Speter hang up under some bizarre circumstances. From Eric 1012138032Speter Wassenaar. 1012238032Speter Fix some server SMTP synchronization problems caused when 1012338032Speter connections fail during message collection. From 1012438032Speter Eric Wassenaar. 1012538032Speter Fix a problem that can cause srvrsmtp to reject mail if the 1012638032Speter name server is down -- it accepts the RCPT but rejects 1012738032Speter the DATA command. Problem reported by Jim Murray of 1012838032Speter Stratus. 1012938032Speter Fix a problem that can cause core dumps if the config file 1013038032Speter incorrectly resolves to a null hostname. Reported by 1013138032Speter Allan Johannesen of WPI. 1013238032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 1013338032Speter by non-root users were not put into 1013438032Speter X-Authentication-Warning:s as intended because the 1013543730Speter config file hadn't set the PrivacyOptions yet. Fix 1013638032Speter from Sven-Ove Westberg of the University of Lulea. 1013738032Speter Under very odd circumstances, the alias file rebuild code 1013838032Speter could get confused as to whether a database was 1013938032Speter open or not. 1014038032Speter Check "vendor code" on the end of V lines -- this is 1014138032Speter intended to provide a hook for vendor-specific 1014238032Speter configuration syntax. (This is a "new feature", 1014338032Speter but I've made an exception to my rule in a belief 1014438032Speter that this is a highly exceptional case.) 1014538032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 1014638032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 1014738032Speter (from Jon Forrest of UC Berkeley) 1014838032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 1014938032Speter 1015064562Sgshapiro8.6.1/8.6 1993/10/08 1015138032Speter Portability fixes for A/UX and Encore UMAX V. 1015238032Speter Fix error message handling -- if you had a name server down 1015338032Speter causing an error during parsing, that message was never 1015438032Speter propagated to the queue file. 1015538032Speter 1015664562Sgshapiro8.6/8.6 1993/10/05 1015738032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 1015838032Speter conf.h (other systems have the same bug). 1015938032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 1016038032Speter getdtablesize() instead of sysconf(); a disturbingly 1016138032Speter large number of systems defined _SC_OPEN_MAX in the 1016238032Speter header files but don't have the syscall. 1016338032Speter Another patch to really truly ignore MX records in getcanonname 1016438032Speter if trymx == FALSE. 1016538032Speter Fix problem that caused the "250 IAA25499 Message accepted for 1016638032Speter delivery" message to be omitted if there was an error 1016738032Speter in the header of the message (e.g., a bad Errors-To: 1016838032Speter line). Pointed out by Michael Corrigan of UCSD. 1016938032Speter Announce name of host we are chatting when we get errors; this 1017038032Speter is an IDA-ism suggested by Christophe Wolfhugel. 1017138032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 1017238032Speter Australian Artificial Intelligence Institute), SCO Unix 1017338032Speter (from Murray Kucherawy of Hookup Communication Corp.), 1017438032Speter NeXT (from Vince DeMarco and myself), Linux (from 1017538032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 1017638032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 1017738032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 1017838032Speter Some changes to get around gcc optimizer bugs. From Takahiro 1017938032Speter Kanbe. 1018038032Speter Fix error recovery in queueup if another tf file of the same 1018138032Speter name already exists. Problem stumbled over by Bill 1018238032Speter Wisner of The Well. 1018338032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 1018438032Speter Problem noted by Keith McMillan of Ameritech Services. 1018538032Speter Deal with group permissions properly when opening .forward and 1018638032Speter :include: files. This relaxes the 8.1C restrictions 1018738032Speter slightly more. This includes proper setting of groups 1018838032Speter when reading :include: files, allowing you to read some 1018938032Speter files that you should be able to read but have previously 1019038032Speter been denied unless you owned them or they had "other" 1019138032Speter read permission. 1019238032Speter Make certain that $j is in $=w (after the .cf is read) so that 1019338032Speter if the user is forced to override some silly system, 1019438032Speter MX suppression will still work. 1019538032Speter Fix a couple of efficiency problems where newstr was double- 1019638032Speter calling expensive routines. In at least one case, it 1019738032Speter wasn't guaranteed that they would always return the 1019838032Speter same result. Problem noted by Christophe Wolfhugel. 1019938032Speter Fix null pointer dereference in putoutmsg -- only on an error 1020038032Speter condition from a non-SMTP mailer. From Motonori 1020138032Speter Nakamura. 1020238032Speter Macro expand "C" line class definitions before scanning so that 1020338032Speter "CX $Z" works. 1020438032Speter Fix problem that caused error message to be sent while still 1020538032Speter trying to send the original message if the connection 1020638032Speter is closed during a DATA command after getting an error 1020738032Speter on an RCPT command (pretty obscure). Problem reported 1020838032Speter by John Myers of CMU. 1020938032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 1021038032Speter term bug. 1021138032Speter Fix a nasty bug causing core dumps when returning the "warning: 1021238032Speter cannot deliver for N hours -- will keep trying" message; 1021343730Speter it only occurred if you had PostmasterCopy set and 1021438032Speter only on some architectures. Although sendmail would 1021538032Speter keep trying, it would send error messages on each 1021638032Speter queue interval. This is an important fix. 1021738032Speter Allow u and g options to take user and group names respectively. 1021838032Speter Don't do a chdir into the queue directory in -bt mode to make 1021938032Speter ruleset testing a bit easier. 1022038032Speter Don't allow users to turn off logging (using -oL) on the command 1022138032Speter line -- command line can only raise, not lower, logging 1022238032Speter level. 1022338032Speter Set $u to the original recipient on the SMTP transaction or on 1022438032Speter the command line. This is only done if there is exactly 1022538032Speter one recipient. Technically, this does not meet the 1022638032Speter specs, because it does not guarantee a domain on the 1022738032Speter address. 1022838032Speter Fix a problem that dumped error messages on bad addresses if 1022938032Speter you used the -t flag. Problem noted by Josh Smith of 1023038032Speter Harvey Mudd College. 1023138032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 1023238032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 1023338032Speter avoid the problem of people who use angle brackets in 1023438032Speter their full name information. 1023538032Speter Fix a null pointer dereference if you set option "l", have 1023638032Speter an Errors-To: header in the message, and have Errors-To: 1023738032Speter defined in the config file H lines. From J.R. Oldroyd. 1023838032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 1023938032Speter wrong when compiling. Suggested by Rick McCarty of TI. 1024038032Speter Fix a problem that could pass negative SIZE parameter if the 1024138032Speter df file got lost; this would cause servers to always 1024238032Speter give a temporary failure, making the problem even worse. 1024338032Speter Problem noted by Allan Johannesen of WPI. 1024438032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 1024538032Speter protocol timeouts (30s default). Requested by Murray 1024638032Speter Kucherawy of HookUp Communication Corp. to handle bogus 1024738032Speter PC TCP/IP implementations. 1024838032Speter Change $w default definition to be just the first component of 1024938032Speter the domain name on config level 5. The $j macro defaults 1025038032Speter to the FQDN; $m remains as before. This lets well-behaved 1025138032Speter config files use any of the short, long, or subdomain 1025238032Speter names. 1025338032Speter Add makesendmail script in src to try to automate multi-architecture 1025438032Speter builds. I know, this is sub-optimal, but it is still 1025538032Speter helpful. 1025638032Speter Fix very obscure race condition that can cause a queue run to 1025738032Speter get a queue file for an already completed job. This 1025838032Speter problem has existed for years. Problem noted by the 1025938032Speter long suffering Allan Johannesen of WPI. 1026038032Speter Fix a problem that caused the raw sender name to be passed to 1026138032Speter udbsender instead of the canonified name -- this caused 1026238032Speter it to sometimes miss records that it should have found. 1026338032Speter Relax check of name on HELO packet so that a program using -bs 1026438032Speter that claims to be itself works properly. 1026538032Speter Restore rewriting of $: part of address through 2, R, 4 in 1026638032Speter buildaddr -- this requires passing a lot of flags to get 1026738032Speter it right. Unlike old versions, this ONLY rewrites 1026838032Speter recipient addresses, not sender addresses. 1026938032Speter Fix a bug that caused core dumps in config files that cannot 1027038032Speter resolve /file/name style addresses. Fix from Jonathan 1027138032Speter Kamens of OpenVision Technologies. 1027238032Speter Fix problem with fcntl locking that can cause error returns to 1027338032Speter be lost if the lock is lost; this required fully 1027438032Speter queueing everything, dropping the envelope (so errors 1027538032Speter would get returned), and then re-reading the queue from 1027638032Speter scratch. 1027738032Speter Fix a problem that caused aliases that redefine an otherwise 1027838032Speter true address to still send to the original address 1027938032Speter if and only if the alias failed in certain bizarre 1028038032Speter ways (e.g, if they pointed at a list:; syntax address). 1028138032Speter Problem pointed out by Jonathan Kamens. 1028238032Speter Remove support for frozen configuration files. They caused 1028338032Speter more trouble than it was worth. 1028438032Speter Fix problem that can cause error messages to get ignored when 1028538032Speter using both -odb and -t flags. Problem noted by Rob 1028638032Speter McNicholas at U.C. Berkeley. 1028738032Speter Include all "normal" variations on hostname in $=w. For example, 1028838032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 1028938032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 1029038032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 1029138032Speter the queue. 1029238032Speter Reset SmtpPhase global on initial connection creation so that 1029338032Speter messages don't come out with stale information. 1029438032Speter Pass an "ext" argument to lockfile so that error/log messages 1029538032Speter will properly reflect the true filename being locked. 1029638032Speter Put all [...] address forms into $=w -- this eliminates the need 1029738032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 1029838032Speter Myers of CMU. 1029938032Speter Fix a bug that can cause qf files to be left around even after 1030038032Speter an SMTP RSET command. Problem and fix from Michael 1030138032Speter Corrigan. 1030243730Speter Don't send a PostmasterCopy to errors when the Precedence: is 1030338032Speter negative. Error reports still go to the envelope 1030438032Speter sender address. 1030538032Speter Add LA_SHORT for load averages. 1030638032Speter Lock sendmail.st file when posting statistics. 1030738032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 1030838032Speter set the size of the TCP send and receive buffers; if you 1030938032Speter run over a slow slip line you may need to set these down 1031038032Speter (although it would be better to fix the SLIP implementation 1031138032Speter so that it's not necessary to recompile every program 1031238032Speter that does bulk data transfer). 1031338032Speter Allow null defaults on $( ... $) lookups. Problem reported by 1031438032Speter Amir Plivatsky. 1031538032Speter Diagnose crufty S and V config lines. This resulted from an 1031638032Speter observation that some people were using the SITE macro 1031738032Speter without the SITECONFIG macro first, which was causing 1031838032Speter bogus config files that were not caught. 1031938032Speter Fix makemap -f flag to turn off case folding (it was turning it 1032038032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 1032138032Speter Fix a problem that caused multiple error messages to be sent if 1032238032Speter you used "sendmail -t -oem -odb", your system uses fcntl 1032338032Speter locking, and one of the recipient addresses is unknown. 1032438032Speter Reset uid earlier in include() so that recursive .forwards or 1032538032Speter :include:s don't use the wrong uid. 1032638032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 1032738032Speter called, the code to recover the descriptor was broken. 1032838032Speter This sometimes (only sometimes) caused problems with the 1032938032Speter alias file. Fix from Motonori Nakamura. 1033038032Speter Fix a problem that caused aliaswait to go into infinite recursion 1033138032Speter if the @:@ metasymbol wasn't found in the alias file. 1033238032Speter Improve error message on newaliases if database files cannot be 1033338032Speter opened or if running with no database format defined. 1033438032Speter Do a better estimation of the size of error messages when NoReturn 1033538032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 1033638032Speter Fix a problem causing the "c" option (don't connect to expensive 1033738032Speter mailers) to be ignored in SMTP. Problem noted and the 1033838032Speter solution suggested by Robert Elz of The University of 1033938032Speter Melbourne. 1034038032Speter Improve connection caching algorithm by passing "[host]" to 1034138032Speter hostsignature, which strips the square brackets and 1034238032Speter returns the real name. This allows mailertable entries 1034338032Speter to match regular entries. 1034438032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 1034538032Speter feature, even if it doesn't work right. 1034638032Speter Catch and log attempts to try the "wiz" command in server SMTP. 1034738032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 1034838032Speter Be more generous at assigning $z to the home directory -- do this 1034938032Speter for programs that are specified through a .forward file. 1035038032Speter Fix from Andrew Chang of Sun Microsystems. 1035138032Speter Always save a fatal error message in preference to a non-fatal 1035238032Speter error message so that the "subject" line of return 1035338032Speter messages is the best possible. 1035438032Speter CONFIG: reduce the number of quotes needed to quote configuration 1035538032Speter parameters with commas: two quotes should work now, e.g., 1035638032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 1035738032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 1035838032Speter connections (domain-ized UUCP). 1035938032Speter CONFIG: fix bug in default maps (-o must be before database file 1036064562Sgshapiro name). Pointed out by Christophe Wolfhugel. 1036138032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 1036238032Speter DNS. This would presumably be used in UUCP islands. 1036338032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 1036438032Speter CONFIG: log $u in Received: line. This is in technical violation 1036538032Speter of the standards, since it doesn't guarantee a domain 1036638032Speter on the address. 1036738032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 1036838032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 1036938032Speter the "m" flag should you want it. Apparently some Solaris 2.2 1037038032Speter installations can't handle multiple local recipients. 1037138032Speter Problem noted by Josh Smith. 1037238032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 1037338032Speter CONFIG: change default version level from 4 to 5. 1037438032Speter CONFIG: add FEATURE(nullclient) to create a config file that 1037538032Speter forwards all mail to a hub without ever looking at the 1037638032Speter addresses in any detail. 1037738032Speter CONFIG: properly strip mailer: information off of relays when 1037838032Speter used to change .BITNET form into %-hack form. 1037938032Speter CONFIG: fix a problem that caused infinite loops if presented 1038038032Speter with an address such as "!foo". 1038138032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 1038238032Speter the reverse "PTR" mapping is broken. There's a better 1038338032Speter way to do this, but the change is fairly major and I 1038438032Speter want to hold it for another release. Problem noted by 1038538032Speter Bret Marquis. 1038638032Speter 1038764562Sgshapiro8.5/8.5 1993/07/23 1038838032Speter Serious bug: if you used a command line recipient that was unknown 1038938032Speter sendmail would not send a return message (it was treating 1039038032Speter everything as though it had an SMTP-style client that 1039138032Speter would do the return itself). Problem noted by Josh Smith. 1039238032Speter Change "trymx" option in getcanonname() to ignore all MX data, 1039338032Speter even during a T_ANY query. This actually didn't break 1039438032Speter anything, because the only time you called getcanonname 1039538032Speter with !trymx was if you already knew there were no MX 1039638032Speter records, but it is somewhat cleaner. From Motonori 1039738032Speter Nakamura. 1039838032Speter Don't call getcanonname from getmxrr if you already know there 1039938032Speter are no DNS records matching the name. 1040038032Speter Fix a problem causing error messages to always include "The 1040138032Speter original message was received ... from localhost". 1040238032Speter The correct original host information is now included. 1040338032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 1040438032Speter version of "test" doesn't have the -x flag). Change it 1040538032Speter to use -f instead. From John Myers. 1040638032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 1040738032Speter esmtp -- it should be smtp. 1040838032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 1040938032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 1041038032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 1041138032Speter this cleans up the configs somewhat. This fixes a serious 1041238032Speter problem that caused route-addrs to get mistaken as relays, 1041338032Speter pointed out by John Myers. WARNING: this also causes 1041438032Speter the default on SMART_HOST to change from "suucp" to 1041538032Speter "relay" if you have MAILER(smtp) specified. 1041638032Speter 1041764562Sgshapiro8.4/8.4 1993/07/22 1041838032Speter Add option `w'. If you receive a message that comes to you because 1041938032Speter you are the best (lowest preference) target of an MX, and 1042038032Speter you haven't explicitly recognized the source MX host in 1042138032Speter your .cf file, this option will cause you to try the target 1042238032Speter host directly (as if there were no MX for it at all). If 1042338032Speter `w' is not set, this case is a configuration error. 1042438032Speter Beware: if `w' is set, senders may get bogus errors like 1042538032Speter "message timed out" or "host unknown" for problems that 1042638032Speter are really configuration errors. This option is 1042738032Speter disrecommended, provided only for compatibility with 1042838032Speter UIUC sendmail. 1042938032Speter Fix a problem that caused the incoming socket to be left open 1043038032Speter when sendmail forks after the DATA command. This caused 1043138032Speter calling systems to wait in FIN_WAIT_2 state until the 1043238032Speter entire list was processed and the child closed -- a 1043338032Speter potentially prodigious amount of time. Problem noted 1043438032Speter by Neil Rickert. 1043538032Speter Fix problem (created in 6.64) that caused mail sent to multiple 1043638032Speter addresses, one of which was a bad address, to completely 1043738032Speter suppress the sending of the message. This changes 1043838032Speter handling of EF_FATALERRS somewhat, and adds an 1043938032Speter EF_GLOBALERRS flag. This also fixes a potential problem 1044038032Speter with duplicate error messages if there is a syntax error 1044138032Speter in the header of a message that isn't noticed until late 1044238032Speter in processing. Original problem pointed out by Josh Smith 1044338032Speter of Harvey Mudd College. This release includes quite a bit 1044438032Speter of dickering with error handling (see below). 1044538032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 1044638032Speter will only hurt already-broken software and should help 1044738032Speter humans. 1044838032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 1044938032Speter compiled in. It would never read the alias file. 1045038032Speter Repair unbalanced `)' and `>' (the "open" versions are already 1045138032Speter repaired). 1045238032Speter Logging of "done" in dropenvelope() was incorrect: it would 1045338032Speter log this even when the queue file still existed. Change 1045438032Speter this to only log "done" (at log level 11) when the 1045538032Speter queue file is actually removed. From John Myers. 1045638032Speter Log "lost connection" in server SMTP at log level 20 if there 1045738032Speter is no pending transaction. Some senders just close the 1045838032Speter connection rather than sending QUIT. 1045938032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 1046038032Speter domains that do not have MX records -- this would cause 1046138032Speter the subsequent host name lookup to fail. The problem 1046238032Speter only occurred if you had FEATURE(nocanonify) set. 1046338032Speter Problem noted by Rick McCarty of Texas Instruments. 1046438032Speter Fix invocation of setvbuf when passed a -X flag -- I had 1046538032Speter unwittingly used an ANSI C extension, and this caused 1046638032Speter core dumps on some machines. 1046738032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 1046838032Speter Previously it just gave an empty send queue, which 1046938032Speter then gave either "Need RCPT (recipient)" at the DATA 1047038032Speter (confusing, since you had given an RCPT command which 1047138032Speter returned 250) or just dropped the email, depending on 1047238032Speter whether you were running VERBose mode. Now it usually 1047338032Speter diagnoses this case as "aliasing/forwarding loop broken". 1047438032Speter Unfortunately, it still doesn't adequately diagnose 1047538032Speter some true error conditions. 1047638032Speter Add internal concept of "warning messages" using 6xx codes. 1047738032Speter These are not reported only to Postmaster. Unbalanced 1047838032Speter parens, brackets, and quotes are printed as 653 codes. 1047938032Speter They are always mapped to 5xx codes before use in SMTP. 1048038032Speter Clean up error messages to tell both the actual address that 1048138032Speter failed and the alias they arose from. This makes it 1048238032Speter somewhat easier to diagnose problems. Difficulty noted 1048338032Speter by Motonori Nakamura. 1048438032Speter Fix a problem that inappropriately added a ctladdr to addresses 1048538032Speter that shouldn't have had one during a queue run. This 1048638032Speter caused error messages to be handled differently during 1048738032Speter a queue run than a direct run. 1048838032Speter Don't print the qf name and line number if you get errors during 1048938032Speter the direct run of the queue from srvrsmtp -- this was 1049038032Speter just extra stuff for users to crawl through. 1049138032Speter Put command line flags on second line of pid file so you can 1049238032Speter auto-restart the daemon with all appropriate arguments. 1049338032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1049438032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1049538032Speter restart it. 1049638032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1049738032Speter IDENT daemon to screw up. This required that I change 1049838032Speter HASSETEUID to HASSETREUID and complicate the mode 1049938032Speter changing somewhat because both Ultrix and SunOS seem 1050038032Speter to have a bug causing seteuid() to set the saved uid 1050138032Speter as well as the effective. The program test/t_setreuid.c 1050238032Speter will test to see if your implementation of setreuid(2) 1050338032Speter is appropriately functional. 1050438032Speter The FallBackMX (option V) handling failed to properly identify 1050538032Speter fallback to yourself -- most of the code was there, 1050638032Speter but it wasn't being enabled. Problem noted by Murray 1050738032Speter Kucherawy of the University of Waterloo. 1050838032Speter Change :include: open timeout from ETIMEDOUT to an internal 1050938032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1051038032Speter with CurHostName" in error messages, which can be 1051138032Speter confusing. Reported by Jonathan Kamens of OpenVision 1051238032Speter Technologies. 1051338032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1051438032Speter process group id. The original fix was to get around 1051538032Speter some problems with recalcitrant MUAs, but it breaks 1051638032Speter any call from a shell that creates a process group id 1051738032Speter different from the process id. I could try to fix 1051838032Speter this by diddling the tty owner (using tcsetpgrp or 1051938032Speter equivalent) but this is too likely to break other 1052038032Speter things. 1052138032Speter Portability changes: 1052238032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1052338032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1052438032Speter instead of using standard flags. Oh joy. This 1052543730Speter behavior reported by Jon Giltner of University 1052638032Speter of Colorado. 1052738032Speter SGI IRIX -- this includes several changes that should 1052838032Speter help other strict ANSI compilers. 1052938032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1053038032Speter Corporation. 1053138032Speter Solaris running the Sun C compiler (which despite the 1053238032Speter documentation apparently doesn't define 1053338032Speter __STDC__ by default). 1053438032Speter ConvexOS from Eric Schnoebelen of Convex. 1053538032Speter Sony NEWS workstations and Omron LUNA workstations from 1053638032Speter Motonori Nakamura. 1053738032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1053838032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1053938032Speter several people have made a good argument that this 1054038032Speter creates more problems than it solves (although this 1054138032Speter may prove painful in the short run). 1054238032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1054338032Speter format. 1054438032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1054538032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1054638032Speter addresses are also passed through this ruleset. 1054738032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1054838032Speter internet-style addresses would "fall off the end" of 1054938032Speter ruleset zero and be interpreted as local -- however, 1055038032Speter the angle brackets confused the recursive call. 1055138032Speter These are now diagnosed as "Unrecognized host name". 1055238032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1055338032Speter ifdef(`_MAILER_USENET_') instead of 1055438032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1055538032Speter of SINTEF RUNIT, Oslo. 1055638032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1055738032Speter early in ruleset 0; this allows .mc authors to bypass 1055838032Speter things like the "short circuit" code for local addresses. 1055938032Speter Prompted by a comment by Bill Wisner of The Well. 1056038032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1056138032Speter esmtp) to send SMTP mail. This allows you to default 1056238032Speter to esmtp but use a mailertable or other override to 1056338032Speter deal with broken servers. This logic was pointed out 1056438032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1056538032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1056638032Speter environments. Ugly as sin. 1056738032Speter 1056864562Sgshapiro8.3/8.3 1993/07/13 1056938032Speter Fix setuid problems introduced in 8.2 that caused messages 1057038032Speter like "Cannot create qfXXXXXX: Invalid argument" 1057138032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1057238032Speter involved a new compile flag "HASSETEUID" that takes 1057338032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1057438032Speter that the POSIX interface is broken enough to break 1057538032Speter some systems badly. This includes some fixes for 1057638032Speter HP-UX. Also fixes problems where the real uid is 1057738032Speter not reset properly on startup (from Neil Rickert). 1057838032Speter Fix a problem that caused timed out messages to not report the 1057938032Speter addresses that timed out. Error messages are also more 1058038032Speter "user friendly". 1058138032Speter Drop required bandwidth on connections from 64 bytes/sec to 1058238032Speter 16 bytes/sec. 1058338032Speter Further Solaris portability changes -- doesn't require the BSD 1058438032Speter compatibility library. This also adds a new 1058538032Speter "HASGETDTABLESIZE" compile flag which can be used if 1058638032Speter you want to use getdtablesize(2) instead of sysconf(2). 1058738032Speter These are loosely based on changes from David Meyer at 1058838032Speter University of Oregon. This now seems to work, at least 1058938032Speter for quick test cases. 1059038032Speter Fix a problem that can cause duplicate error messages to be 1059138032Speter sent if you are in SMTP, you send to multiple addresses, 1059238032Speter and at least one of those addresses is good and points 1059338032Speter to an account that has a .forward file (whew!). 1059438032Speter Fix a problem causing messages to be discarded if checkcompat() 1059538032Speter returned EX_TEMPFAIL (because it didn't properly mark 1059638032Speter the "to" address). Problem noted by John Myers. 1059738032Speter Fix dfopen to return NULL if the open failed; I was depending 1059838032Speter on fdopen(-1) returning NULL, which isn't the case. This 1059938032Speter isn't serious, but does result in weird error diagnoses. 1060038032Speter From Michael Corrigan. 1060138032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1060238032Speter messages sent through UUCP-family mailers. Suggested 1060338032Speter by Bill Wisner of The Well. 1060438032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1060538032Speter include a "uucp-dom" mailer that uses domain-style 1060638032Speter addressing. Suggested by Bill Wisner. 1060738032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1060838032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1060938032Speter Christophe Wolfhugel. 1061038032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1061138032Speter 1061264562Sgshapiro8.2/8.2 1993/07/11 1061338032Speter Don't drop out on config file parse errors in -bt mode. 1061438032Speter On older configuration files, assume option "l" (use Errors-To 1061538032Speter header) for back compatibility. NOTE: this DOES NOT 1061638032Speter imply an endorsement of the Errors-To: header in any way. 1061738032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1061838032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1061938032Speter SMTP server to give an error on this command, and 1062038032Speter logging it in the transcript can be confusing. Fix 1062138032Speter from Bill Wisner. 1062238032Speter IRIX compatibility changes provided by Dan Rich 1062338032Speter <drich@sandman.lerc.nasa.gov>. 1062438032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1062538032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1062638032Speter <juo@klinzhai.rutgers.edu> 1062738032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1062838032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1062938032Speter match the other flags in that file. 1063038032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1063138032Speter Save h_errno in mci struct and improve error message display. 1063238032Speter Changes from Eric Wassenaar. 1063338032Speter Open /dev/null for the transcript if the create of the xf file 1063438032Speter failed; this avoids at least one possible null pointer 1063538032Speter reference in very weird cases. From Eric Wassenaar. 1063638032Speter Clean up statistics gathering; it was over-reporting because of 1063738032Speter forks. From Eric Wassenaar. 1063838032Speter Fix problem that causes old Return-Path: line to override new 1063938032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1064038032Speter re-using old value). From Motonori Nakamura. 1064138032Speter Fix broken -m flag in K definition -- even if -m (match only) 1064238032Speter was specified, it would still replace the key with the 1064338032Speter value. Noted by Rick McCarty of Texas Instruments. 1064438032Speter If the name server timed out over several days, no "timed out" 1064538032Speter message would ever be sent back. The timeout code 1064638032Speter has been moved from markfailure() to dropenvelope() 1064738032Speter so that all such failures should be diagnosed. Pointed 1064838032Speter out by Christophe Wolfhugel and others. 1064938032Speter Relax safefile() constraints: directories in an include or 1065038032Speter forward path must be readable by self if the controlling 1065138032Speter user owns the entry, readable by all otherwise (e.g., 1065238032Speter when reading your .forward file, you have to own and 1065338032Speter have X permission in it; everyone needs X permission in 1065438032Speter the root and directories leading up to your home); 1065538032Speter include files must be readable by anyone, but need not 1065638032Speter be owned by you. 1065738032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1065838032Speter reading a .forward file; this gets around some problems 1065938032Speter on NFS mounts if root permission is not exported and 1066038032Speter the user's home directory isn't x'able. 1066138032Speter Additional NeXT portability enhancements from Axel Zinser. 1066238032Speter Additional HP-UX portability enhancements from Brian Bullen. 1066338032Speter Add a timeout around SMTP message writes; this assumes you can 1066438032Speter get throughput of at least 64 bytes/second. Note that 1066538032Speter this does not impact the "datafinal" default, which 1066638032Speter is separate; this is just intended to work around 1066738032Speter network clogs that will occur before the final dot 1066838032Speter is sent. From Eric Wassenaar. 1066938032Speter Change map code to set the "include null" flag adaptively -- 1067038032Speter it initially tries both, but if it finds anything 1067138032Speter matching without a null it never tries again with a 1067238032Speter null and vice versa. If -N is specified, it never 1067338032Speter tries without the null and creates new maps with a 1067438032Speter null byte. If -O is specified, it never tries with 1067538032Speter the null (for efficiency). If -N and -O are specified, 1067638032Speter you get -NO (get it?) lookup at all, so this would 1067738032Speter be a bad idea. If you don't specify either -N or -O, 1067838032Speter it adapts. 1067938032Speter Fix recognition of "same from address" so that MH submissions 1068038032Speter will insert the appropriate full name information; 1068138032Speter this used to work and got broken somewhere along the 1068238032Speter way. 1068338032Speter Some changes to eliminate some unnecessary SYSERRs in the 1068438032Speter log. For example, if you lost a connection, don't 1068538032Speter bother reporting that fact on the connection you lost. 1068638032Speter Add some "extended debugging" flags to try to track down 1068738032Speter why we get occasional problems with file descriptor 1068838032Speter one being closed when execing a mailer; it seems to 1068938032Speter only happen when there has been another error in the 1069038032Speter same transaction. This requires XDEBUG, defined 1069138032Speter by default in conf.h. 1069238032Speter Add "-X filename" command line flag, which logs both sides of 1069338032Speter all SMTP transactions. This is intended ONLY for 1069438032Speter debugging bad implementations of other mailers; start 1069538032Speter it up, send a message from a mailer that is failing, 1069638032Speter and then kill it off and examine the indicated log. 1069738032Speter This output is not intended to be particularly human 1069838032Speter readable. This also adds the HASSETVBUF compile 1069938032Speter flag, defaulted on if your compiler defines __STDC__. 1070038032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1070138032Speter have a local net that should get direct connects, you 1070238032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1070338032Speter See cf/README for an example. 1070438032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1070538032Speter sites that don't use the -d flag. 1070638032Speter CONFIG: hide recipient addresses as well as sender addresses 1070738032Speter behind $M if FEATURE(allmasquerade) is specified; this 1070838032Speter has been requested by several people, but can break 1070938032Speter local aliases. For example, if you mail to "localalias" 1071038032Speter this will be rewritten as "localalias@masqueradehost"; 1071138032Speter although initial delivery will work, replies will be 1071238032Speter broken. Use it sparingly. 1071338032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1071438032Speter to qualified domains in headers. I believe this is 1071538032Speter largely equivalent to the IDA feature of the same name. 1071638032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1071738032Speter to override the "system name" as your UUCP name -- 1071838032Speter in particular, to use domain-ized UUCP names. From 1071938032Speter Bill Wisner of The Well. 1072038032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1072138032Speter first. This is currently unused in the config files, 1072238032Speter but could be used in a mailertable entry. 1072338032Speter 1072464562Sgshapiro8.1C/8.1B 1993/06/27 1072538032Speter Serious security bug fix: it was possible to read any file on 1072638032Speter the system, regardless of ownership and permissions. 1072738032Speter If a subroutine returns a fully qualified address, return it 1072838032Speter immediately instead of feeding it back into rewriting. 1072938032Speter This fixes a problem with mailertable lookups. 1073038032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1073138032Speter 1073264562Sgshapiro8.1B/8.1A 1993/06/12 1073338032Speter Serious bug fix: pattern matching backup algorithm stepped by 1073438032Speter two tokens in classes instead of one.
