Sites can +# override the built-in information by specifying a bounce +# template file with the \fBbounce_template_file\fR configuration +# parameter. +# +# This document describes the general procedure to create a +# bounce template file, followed by the specific details of +# bounce template formats. +# GENERAL PROCEDURE +# .ad +# .fi +# To create a customized bounce template file, create a +# temporary +# copy of the file \fB/etc/postfix/bounce.cf.default\fR and +# edit the temporary file. +# +# To preview the results of $\fIname\fR expansions in the +# template text, use the command +# +# .nf +# \fBpostconf -b\fR \fItemporary_file\fR +# .fi +# +# Errors in the template will be reported to the standard +# error stream and to the syslog daemon. +# +# While previewing the text, be sure to pay particular attention +# to the expansion of time value parameters that appear in +# the delayed mail notification text. +# +# Once the result is satisfactory, copy the template to the +# Postfix configuration directory and specify in main.cf +# something like: +# +# .nf +# /etc/postfix/main.cf: +# bounce_template_file = /etc/postfix/bounce.cf +# .fi +# TEMPLATE FILE FORMAT +# .ad +# .fi +# The template file can specify templates for failed mail, +# delayed mail, successful delivery or for address verification. +# These templates are named \fBfailure_template\fR, +# \fBdelay_template\fR, \fBsuccess_template\fR and +# \fBverify_template\fR, respectively. You can but do not +# have to specify all four templates in a bounce template +# file. +# +# Each template starts with "\fItemplate_name\fB = <<EOF\fR" +# and ends with a line that contains the word "\fBEOF\fR" +# only. You can change the word EOF, but you can't enclose +# it in quotes as with the shell or with Perl (\fItemplate_name\fB +# = <<'EOF'\fR). Here is an example: +# +# .nf +# # The failure template is used for undeliverable mail. +# +# failure_template = <<EOF +# Charset: us-ascii +# From: MAILER-DAEMON (Mail Delivery System) +# Subject: Undelivered Mail Returned to Sender +# Postmaster-Subject: Postmaster Copy: Undelivered Mail +# +# This is the mail system at host $myhostname. +# +# I'm sorry to have to inform you that your message could not +# be delivered to one or more recipients. It's attached below. +# +# For further assistance, please send mail to postmaster. +# +# If you do so, please include this problem report. You can +# delete your own text from the attached returned message. +# +# The mail system +# EOF +# .fi +# .PP +# The usage and specification of bounce templates is +# subject to the following restrictions: +# .IP \(bu +# No special meaning is given to the backslash character or +# to leading whitespace; these are always taken literally. +# .IP \(bu +# Inside the << context, the "$" character is special. To +# produce a "$" character as output, specify "$$". +# .IP \(bu +# Outside the << context, lines beginning with "#" are ignored, +# as are empty lines, and lines consisting of whitespace only. +# .PP +# Examples of all templates can be found in the file +# \fBbounce.cf.default\fR in the Postfix configuration +# directory. +# TEMPLATE HEADER FORMAT +# .ad +# .fi +# The first portion of a bounce template consists of optional +# template headers. Some become message headers in the +# delivery status notification; some control the formatting +# of that notification. Headers not specified in a template +# will be left at their default value. +# +# The following headers are supported: +# .IP \fBCharset:\fR +# The MIME character set of the template message text. See +# the "TEMPLATE MESSAGE TEXT FORMAT" description below. +# .IP \fBFrom:\fR +# The sender address in the message header of the delivery +# status notification. +# .IP \fBSubject:\fR +# The subject in the message header of the delivery status +# notification that is returned to the sender. +# .IP \fBPostmaster-Subject:\fR +# The subject that will be used in Postmaster copies of +# undeliverable or delayed mail notifications. These copies +# are sent under control of the notify_classes configuration +# parameter. +# .PP +# The usage and specification of template message headers is +# subject to the following restrictions: +# .IP \(bu +# Template message header names can be specified in upper +# case, lower case or mixed case. Postfix always produces +# bounce message header labels of the form "\fBFrom:\fR" and +# "\fBSubject:\fR". +# .IP \(bu +# Template message headers must not span multiple lines. +# .IP \(bu +# Template message headers do not support $parameter expansions. +# .IP \(bu +# Template message headers must contain ASCII characters only, +# and must not contain ASCII null characters. +# TEMPLATE MESSAGE TEXT FORMAT +# .ad +# .fi +# The second portion of a bounce template consists of message +# text.
