Sites can override the built-in + information by specifying a bounce template file with the <b><a href="postconf.5.html#bounce_template_file">bounce_tem</a>-</b> + <b><a href="postconf.5.html#bounce_template_file">plate_file</a></b> 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. + +<b>GENERAL PROCEDURE</b> + To create a customized bounce template file, create a temporary copy of + the file <b>/etc/postfix/bounce.cf.default</b> and edit the temporary file. + + To preview the results of $<i>name</i> expansions in the template text, use + the command + + <b>postconf -b</b> <i>temporary</i><b>_</b><i>file</i> + + 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 <a href="postconf.5.html">main.cf</a> something like: + + /etc/postfix/<a href="postconf.5.html">main.cf</a>: + <a href="postconf.5.html#bounce_template_file">bounce_template_file</a> = /etc/postfix/bounce.cf + +<b>TEMPLATE FILE FORMAT</b> + The template file can specify templates for failed mail, delayed mail, + successful delivery or for address verification. These templates are + named <b>failure_template</b>, <b>delay_template</b>, <b>success_template</b> and <b>ver-</b> + <b>ify_template</b>, respectively. You can but do not have to specify all + four templates in a bounce template file. + + Each template starts with "<i>template</i><b>_</b><i>name</i> <b>=</b> <<<b>EOF</b>" and ends with a line + that contains the word "<b>EOF</b>" only. You can change the word EOF, but you + can't enclose it in quotes as with the shell or with Perl (<i>tem-</i> + <i>plate</i><b>_</b><i>name</i> <b>=</b> <<<b>'EOF'</b>). 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 $<a href="postconf.5.html#myhostname">myhostname</a>. + + I'm sorry to have to inform you that your message could not + be delivered to one or more recipients. It's attached below. + + For further assistance, please send mail to postmaster. + + If you do so, please include this problem report. You can + delete your own text from the attached returned message. + + The mail system + EOF + + The usage and specification of bounce templates is subject to the fol- + lowing restrictions: + + <b>o</b> No special meaning is given to the backslash character or to + leading whitespace; these are always taken literally. + + <b>o</b> Inside the << context, the "$" character is special. To produce + a "$" character as output, specify "$$". + + <b>o</b> 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 <b>bounce.cf.default</b> in + the Postfix configuration directory. + +<b>TEMPLATE HEADER FORMAT</b> + 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: + + <b>Charset:</b> + The MIME character set of the template message text. See the + "TEMPLATE MESSAGE TEXT FORMAT" description below. + + <b>From:</b> The sender address in the message header of the delivery status + notification. + + <b>Subject:</b> + The subject in the message header of the delivery status notifi- + cation that is returned to the sender. + + <b>Postmaster-Subject:</b> + The subject that will be used in Postmaster copies of undeliver- + able or delayed mail notifications. These copies are sent under + control of the <a href="postconf.5.html#notify_classes">notify_classes</a> configuration parameter. + + The usage and specification of template message headers is subject to + the following restrictions: + + <b>o</b> 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 "<b>From:</b>" and "<b>Subject:</b>". + + <b>o</b> Template message headers must not span multiple lines. + + <b>o</b> Template message headers do not support $parameter expansions. + + <b>o</b> Template message headers must contain ASCII characters only, and + must not contain ASCII null characters. + +<b>TEMPLATE MESSAGE TEXT FORMAT</b> + The second portion of a bounce template consists of message text. As + the above example shows, template message text may contain <a href="postconf.5.html">main.cf</a> + $parameters. Besides the parameters that are defined in <a href="postconf.5.html">main.cf</a>, the + following parameters are treated specially depending on the suffix that + is appended to their name. + + <b>delay_warning_time_</b><i>suffix</i> + Expands into the value of the <b><a href="postconf.5.html#delay_warning_time">delay_warning_time</a></b> parameter, + expressed in the time unit specified by <i>suffix</i>, which is one of + <b>seconds</b>, <b>minutes</b>, <b>hours, days</b>, or <b>weeks</b>. + + <b>maximal_queue_lifetime_</b><i>suffix</i> + Expands into the value of the <b><a href="postconf.5.html#maximal_queue_lifetime">maximal_queue_lifetime</a></b> parameter, + expressed in the time unit specified by <i>suffix</i>. See above under + <b><a href="postconf.5.html#delay_warning_time">delay_warning_time</a></b> for possible <i>suffix</i> values. + + <b><a href="postconf.5.html#mydomain">mydomain</a></b> + Expands into the value of the <b><a href="postconf.5.html#mydomain">mydomain</a></b> 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. + + <b><a href="postconf.5.html#myhostname">myhostname</a></b> + Expands into the value of the <b><a href="postconf.5.html#myhostname">myhostname</a></b> 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: + + <b>o</b> The template message text is not sent in Postmaster copies of + delivery status notifications. + + <b>o</b> If the template message text contains non-ASCII characters, + Postfix requires that the <b>Charset:</b> 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. + +<b>SEE ALSO</b> + <a href="bounce.8.html">bounce(8)</a>, Postfix delivery status notifications + <a href="postconf.5.html">postconf(5)</a>, configuration parameters + +<b>LICENSE</b> + The Secure Mailer license must be distributed with this software. + +<b>HISTORY</b> + The Postfix bounce template format was originally developed by Nicolas + Riendeau. + +<b>AUTHOR(S)</b> + Wietse Venema + IBM T.J.
