This file shows the default delivery status 6# notification (DSN) messages that are built into Postfix. 7# 8# To change Postfix DSN messages, perhaps to add non-English text, 9# follow instructions in the bounce(5) manual page. 10# 11EOF 12 13# QUICK INSTRUCTIONS: 14# 15#-Edit a temporary copy of this file, and preview the result of $name 16# expansions with "postconf -b temporary_file". If there are any 17# problems, Postfix will log "warning" or "fatal" messages to the 18# maillog file. 19# 20#-The template file can specify bounce message templates for 21# failed mail, for delayed mail, for successful delivery, or for 22# verbose delivery. You don't have to specify all templates. 23# 24#-Each template starts with "template_name = <<EOF" and ends 25# with a line that contains the word "EOF" only. You can change the 26# word EOF if you like, but you can't do shell/perl/etc like things 27# such as enclosing it in quotes (template_name = <<'EOF'). 28# 29#-Each template consists of a few headers and message text. The 30# headers control what the recipient sees as From: and Subject:, and 31# what MIME information Postfix will generate. 32# 33#-Template message headers must not span multiple lines. 34# 35#-Template message headers must not contain main.cf $parameters. 36# 37#-Template message headers must contain ASCII characters only. 38# 39#-The template message text is not sent in Postmaster copies of 40# delivery status notifications. 41# 42#-Template message text may contain main.cf $parameters. Some 43# parameters have additional features as described below with the 44# delayed mail message template. 45# 46#-Template message text may contain non-ASCII text. In that case you 47# MUST change the character set value in the CHARSET: template header, 48# otherwise Postfix will not use your template. You must specify a 49# character set that is a superset of US-ASCII, because Postfix 50# appends ASCII text after the message template when it sends a 51# delivery status notification. 52# 53#-When previewing the result with "postconf -b temporary_file", be 54# sure to pay particular attention to the time values that appear 55# in the delayed mail notification text. 56# 57#-Once you're satisfied with the result, and once Postfix stops 58# logging warning messages, copy the template to the Postfix 59# configuration directory and specify in main.cf something like: 60# 61# /etc/postfix/main.cf: 62# bounce_template_file = $config_directory/bounce.cf 63# 64#EOF 65 66IFS= 67while read line; do 68 case "$line" in 69 failure_template*) cat <<'EOF' 70 71# 72# The failure template is used when mail is returned to the sender; 73# either the destination rejected the message, or the destination 74# could not be reached before the message expired in the queue. 75# 76 77EOF 78 ;; 79 delay_template*) cat <<'EOF' 80 81# 82# The delay template is used when mail is delayed.

There are no other 89# main.cf parameters that have this special behavior. 90# 91# You need to adjust these suffixes (and the surrounding text) if 92# you have very different settings for these time parameters. 93# 94 95EOF 96 ;; 97 success_template*) cat <<'EOF' 98 99# 100# The success template is used when mail is delivered to mailbox, 101# when an alias or list is expanded, or when mail is delivered to a 102# system that does not announce DSN support.
