# Global Postfix configuration file. This file lists only a subset

|
# of all parameters. For the syntax, and for a complete parameter
|
|
# list, see the postconf(5) manual page (command: "man 5 postconf").
|
|
#
|
|
# For common configuration examples, see BASIC_CONFIGURATION_README
|
|
# and STANDARD_CONFIGURATION_README. To find these documents, use
|
|
# the command "postconf html_directory readme_directory", or go to
|
|
# http://www.postfix.org/BASIC_CONFIGURATION_README.html etc.

|
|
# For best results, change no more than 2-3 parameters at a time,
|
|
# and test if Postfix still works after every change.
|

|
# COMPATIBILITY
|
|
#
|
|
# The compatibility_level determines what default settings Postfix
|
|
# will use for main.cf and master.cf settings. These defaults will
|
|
# change over time.
|
|
#
|
|
# To avoid breaking things, Postfix will use backwards-compatible
|
|
# default settings and log where it uses those old backwards-compatible
|
|
# default settings, until the system administrator has determined
|
|
# if any backwards-compatible default settings need to be made
|
|
# permanent in main.cf or master.cf.
|
|
#
|
|
# When this review is complete, update the compatibility_level setting
|
|
# below as recommended in the RELEASE_NOTES file.
|
|
#
|
|
# The level below is what should be used with new (not upgrade) installs.

# SOFT BOUNCE
|
|
#
|
|
# The soft_bounce parameter provides a limited safety net for
|
|
# testing. When soft_bounce is enabled, mail will remain queued that
|
|
# would otherwise bounce. This parameter disables locally-generated
|
|
# bounces, and prevents the SMTP server from rejecting mail permanently
|
|
# (by changing 5xx replies into 4xx replies). However, soft_bounce
|
|
# is no cure for address rewriting mistakes or mail routing mistakes.

# - You define $mydestination domain recipients in files other than

# FAST ETRN SERVICE

# "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld".
|
|
# See the ETRN_README document for a detailed description.
|

# The fast_flush_domains parameter controls what destinations are

# code in the SMTP server's greeting banner. Some people like to see
|
|
# the mail version advertised. By default, Postfix shows no version.
|

# and expensive pipelines in .forward files can cause disasters when

|
# too many are run at the same time. With SMTP deliveries, 10

|
# simultaneous connections to the same domain could be sufficient to
|
|
# raise eyebrows.
