+NAME
+       bounce - Postfix bounce message template format
+
+SYNOPSIS
+       bounce_template_file = /etc/postfix/bounce.cf
+
+       postconf -b [template_file]
+
+DESCRIPTION
+       The  Postfix  bounce(8)  server  produces  delivery status notification
+       (DSN) messages for undeliverable mail, delayed mail, successful  deliv-
+       ery 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 bounce_tem-
+       plate_file configuration parameter.
+
+       This document describes the general procedure to create a  bounce  tem-
+       plate  file,  followed  by the specific details of bounce template for-
+       mats.
+
+GENERAL PROCEDURE
+       To create a customized bounce template file, create a temporary copy of
+       the file /etc/postfix/bounce.cf.default and edit the temporary file.
+
+       To  preview  the  results of $name expansions in the template text, use
+       the command
+
+           postconf -b temporary_file
+
+       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 con-
+       figuration directory and specify in main.cf something like:
+
+       /etc/postfix/main.cf:
+           bounce_template_file = /etc/postfix/bounce.cf
+
+TEMPLATE FILE FORMAT
+       The template file can specify templates for failed mail, delayed  mail,
+       successful  delivery  or for address verification.  These templates are
+       named  failure_template,  delay_template,  success_template  and   ver-
+       ify_template,  respectively.   You  can  but do not have to specify all
+       four templates in a bounce template file.
+
+       Each template starts with "template_name = <<EOF" and ends with a  line
+       that contains the word "EOF" only. You can change the word EOF, but you
+       can't enclose it in quotes  as  with  the  shell  or  with  Perl  (tem-
+       plate_name = <<'EOF'). Here is an example:
+
+           # 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 $myhostname.
+
+           I'm sorry to have to inform you that your message could not
+           be delivered to one or more recipients. It's attached below.
+
+           For further assistance, please send mail to postmaster.
+
+           If you do so, please include this problem report. You can
+           delete your own text from the attached returned message.
+
+                              The mail system
+           EOF
+
+       The  usage and specification of bounce templates is subject to the fol-
+       lowing restrictions:
+
+       o      No special meaning is given to the  backslash  character  or  to
+              leading whitespace; these are always taken literally.
+
+       o      Inside  the << context, the "$" character is special. To produce
+              a "$" character as output, specify "$$".
+
+       o      Outside the << context, lines beginning with "#" are ignored, as
+              are empty lines, and lines consisting of whitespace only.
+
+       Examples of all templates can be found in the file bounce.cf.default in
+       the Postfix configuration directory.
+
+TEMPLATE HEADER FORMAT
+       The first portion of a bounce template consists  of  optional  template
+       headers.   Some become message headers in the delivery status notifica-
+       tion; 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:
+
+       Charset:
+              The  MIME  character  set of the template message text.  See the
+              "TEMPLATE MESSAGE TEXT FORMAT" description below.
+
+       From:  The sender address in the message header of the delivery  status
+              notification.
+
+       Subject:
+              The subject in the message header of the delivery status notifi-
+              cation that is returned to the sender.
+
+       Postmaster-Subject:
+              The subject that will be used in Postmaster copies of undeliver-
+              able  or delayed mail notifications. These copies are sent under
+              control of the notify_classes configuration parameter.
+
+       The usage and specification of template message headers is  subject  to
+       the following restrictions:
+
+       o      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 "From:" and "Subject:".
+
+       o      Template message headers must not span multiple lines.
+
+       o      Template message headers do not support $parameter expansions.
+
+       o      Template message headers must contain ASCII characters only, and
+              must not contain ASCII null characters.
+
+TEMPLATE MESSAGE TEXT FORMAT
+       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.
+
+       delay_warning_time_suffix
+              Expands into the  value  of  the  delay_warning_time  parameter,
+              expressed  in the time unit specified by suffix, which is one of
+              seconds, minutes, hours, days, or weeks.
+
+       maximal_queue_lifetime_suffix
+              Expands into the value of the maximal_queue_lifetime  parameter,
+              expressed in the time unit specified by suffix.  See above under
+              delay_warning_time for possible suffix values.
+
+       mydomain
+              Expands into the value of the mydomain  parameter.   With  "smt-
+              putf8_enable  = yes", this replaces ACE labels (xn--mumble) with
+              their UTF-8 equivalent.
+
+              This feature is available in Postfix 3.0.
+
+       myhostname
+              Expands into the value of the myhostname parameter.  With  "smt-
+              putf8_enable  = yes", this replaces ACE labels (xn--mumble) with
+              their UTF-8 equivalent.
+
+              This feature is available in Postfix 3.0.
+
+       The usage and specification of template message text is subject to  the
+       following restrictions:
+
+       o      The  template  message  text is not sent in Postmaster copies of
+              delivery status notifications.
+
+       o      If the template  message  text  contains  non-ASCII  characters,
+              Postfix  requires  that the Charset: template header is updated.
+              Specify an appropriate superset  of  US-ASCII.   A  superset  is
+              needed because Postfix appends ASCII text after the message tem-
+              plate when it sends a delivery status notification.
