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