+# SUMMARY
+# Postfix bounce message template format
+# SYNOPSIS
+# \fBbounce_template_file = /etc/postfix/bounce.cf\fR
+#
+# \fBpostconf -b\fR [\fItemplate_file\fR]
+# DESCRIPTION
+# The Postfix \fBbounce\fR(8) server produces delivery status
+# notification (DSN) messages for undeliverable mail, delayed
+# mail, successful delivery or address verification requests.
+#
+# By default, these notifications are generated from built-in
+# templates with message headers and message text. 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. As the above example shows, template message text may
+# contain main.cf $parameters. Besides the parameters that are
+# defined in main.cf, the following parameters are treated
+# specially depending on the suffix that is appended to their
+# name.
+# .IP \fBdelay_warning_time_\fIsuffix\fR
+# Expands into the value of the \fBdelay_warning_time\fR
+# parameter, expressed in the time unit specified by
+# \fIsuffix\fR, which is one of \fBseconds\fR, \fBminutes\fR,
+# \fBhours\fB, \fBdays\fR, or \fBweeks\fR.
+# .IP \fBmaximal_queue_lifetime_\fIsuffix\fR
+# Expands into the value of the \fBmaximal_queue_lifetime\fR
+# parameter, expressed in the time unit specified by
+# \fIsuffix\fR. See above under \fBdelay_warning_time\fR for
+# possible \fIsuffix\fR values.
+# .IP \fBmydomain\fR
+# Expands into the value of the \fBmydomain\fR parameter.
+# With "smtputf8_enable = yes", this replaces ACE labels
+# (xn--mumble) with their UTF-8 equivalent.
+# .sp
+# This feature is available in Postfix 3.0.
+# .IP \fBmyhostname\fR
+# Expands into the value of the \fBmyhostname\fR parameter.
+# With "smtputf8_enable = yes", this replaces ACE labels
+# (xn--mumble) with their UTF-8 equivalent.
+# .sp
+# This feature is available in Postfix 3.0.
+# .PP
+# The usage and specification of template message text is
+# subject to the following restrictions:
+# .IP \(bu
+# The template message text is not sent in Postmaster copies
+# of delivery status notifications.
+# .IP \(bu
+# If the template message text contains non-ASCII characters,
+# Postfix requires that the \fBCharset:\fR template header
+# is updated. Specify an appropriate superset of US-ASCII.
+# A superset is needed because Postfix appends ASCII text
+# after the message template when it sends a delivery status
+# notification.
