#!/bin/sh cat <<'EOF' # # Do not edit this file. This file shows the default delivery status # notification (DSN) messages that are built into Postfix. # # To change Postfix DSN messages, perhaps to add non-English text, # follow instructions in the bounce(5) manual page. # EOF # QUICK INSTRUCTIONS: # #-Edit a temporary copy of this file, and preview the result of $name # expansions with "postconf -b temporary_file". If there are any # problems, Postfix will log "warning" or "fatal" messages to the # maillog file. # #-The template file can specify bounce message templates for # failed mail, for delayed mail, for successful delivery, or for # verbose delivery. You don't have to specify all templates. # #-Each template starts with "template_name = <<EOF" and ends # with a line that contains the word "EOF" only. You can change the # word EOF if you like, but you can't do shell/perl/etc like things # such as enclosing it in quotes (template_name = <<'EOF'). # #-Each template consists of a few headers and message text. The # headers control what the recipient sees as From: and Subject:, and # what MIME information Postfix will generate. # #-Template message headers must not span multiple lines. # #-Template message headers must not contain main.cf $parameters. # #-Template message headers must contain ASCII characters only. # #-The template message text is not sent in Postmaster copies of # delivery status notifications. # #-Template message text may contain main.cf $parameters. Some # parameters have additional features as described below with the # delayed mail message template. # #-Template message text may contain non-ASCII text. In that case you # MUST change the character set value in the CHARSET: template header, # otherwise Postfix will not use your template. You must specify a # character set that is a superset of US-ASCII, because Postfix # appends ASCII text after the message template when it sends a # delivery status notification. # #-When previewing the result with "postconf -b temporary_file", be # sure to pay particular attention to the time values that appear # in the delayed mail notification text. # #-Once you're satisfied with the result, and once Postfix stops # logging warning messages, copy the template to the Postfix # configuration directory and specify in main.cf something like: # # /etc/postfix/main.cf: # bounce_template_file = $config_directory/bounce.cf # #EOF IFS= while read line; do case "$line" in failure_template*) cat <<'EOF' # # The failure template is used when mail is returned to the sender; # either the destination rejected the message, or the destination # could not be reached before the message expired in the queue. # EOF ;; delay_template*) cat <<'EOF' # # The delay template is used when mail is delayed. Note a neat trick: # the default template displays the delay_warning_time value as hours # by appending the _hours suffix to the parameter name; it displays # the maximal_queue_lifetime value as days by appending the _days # suffix. # # Other suffixes are: _seconds, _minutes, _weeks. There are no other # main.cf parameters that have this special behavior. # # You need to adjust these suffixes (and the surrounding text) if # you have very different settings for these time parameters. # EOF ;; success_template*) cat <<'EOF' # # The success template is used when mail is delivered to mailbox, # when an alias or list is expanded, or when mail is delivered to a # system that does not announce DSN support. It is an error to specify # a Postmaster-Subject: here. # EOF ;; verify_template*) cat <<'EOF' # # The verify template is used for address verification (sendmail -bv # address...) or for verbose mail delivery (sendmail -v address...). # It is an error to specify a Postmaster-Subject: here. # EOF ;; esac echo "$line"; done
