+# NAME
+#	bounce 5
+# 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.
