1# Global Postfix configuration file. This file lists only a subset 2# of all parameters. For the syntax, and for a complete parameter 3# list, see the postconf(5) manual page (command: "man 5 postconf"). 4# 5# For common configuration examples, see BASIC_CONFIGURATION_README 6# and STANDARD_CONFIGURATION_README. To find these documents, use 7# the command "postconf html_directory readme_directory", or go to 8# http://www.postfix.org/BASIC_CONFIGURATION_README.html etc. 9# 10# For best results, change no more than 2-3 parameters at a time, 11# and test if Postfix still works after every change. 12 13# SOFT BOUNCE 14# 15# The soft_bounce parameter provides a limited safety net for 16# testing. When soft_bounce is enabled, mail will remain queued that 17# would otherwise bounce. This parameter disables locally-generated 18# bounces, and prevents the SMTP server from rejecting mail permanently 19# (by changing 5xx replies into 4xx replies). However, soft_bounce 20# is no cure for address rewriting mistakes or mail routing mistakes. 21# 22#soft_bounce = no 23 24# LOCAL PATHNAME INFORMATION 25# 26# The queue_directory specifies the location of the Postfix queue. 27# This is also the root directory of Postfix daemons that run chrooted. 28# See the files in examples/chroot-setup for setting up Postfix chroot 29# environments on different UNIX systems. 30# 31queue_directory = /var/spool/postfix 32 33# The command_directory parameter specifies the location of all 34# postXXX commands. 35# 36command_directory = /usr/sbin 37 38# The daemon_directory parameter specifies the location of all Postfix 39# daemon programs (i.e. programs listed in the master.cf file).

The default is to append $myhostname, 89# which is fine for small sites. If you run a domain with multiple 90# machines, you should (1) change this to $mydomain and (2) set up 91# a domain-wide alias database that aliases each user to 92# user@that.users.mailhost. 93# 94# For the sake of consistency between sender and recipient addresses, 95# myorigin also specifies the default domain name that is appended 96# to recipient addresses that have no @domain part. 97# 98#myorigin = $myhostname 99#myorigin = $mydomain 100 101# RECEIVING MAIL 102 103# The inet_interfaces parameter specifies the network interface 104# addresses that this mail system receives mail on.
