Postfix 自訂退信訊息範本

Postfix 版本需要 2.3 以上

先確認版本 → postconf -d | grep mail_version

mail_version = 2.4.5
milter_macro_v = $mail_name $mail_version

可以使用的範本名稱有

failure_template
delay_template
success_template
verify_template

使用方式是用 failure_template = <<EOF 為開頭，EOF 結尾

編輯 vi /etc/postfix/bounce.cf

#
# 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.
failure_template = <<EOF
Charset: utf-8
From: MAILER-DAEMON (Mail Delivery System)
Subject: Undelivered Mail Returned to Sender
Postmaster-Subject: Postmaster Copy: Undelivered Mail

這是在電子郵件系統主機 $myhostname 。

#
# 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.

將設定寫入 /etc/postfix/main.cf

postconf -e ‘bounce_template_file = /etc/postfix/bounce.cf’

執行 postconf -b /etc/postfix/bounce.cf 要認 /etc/postfix/bounce.cf 裡面的變數有成功轉換，或者有沒有錯誤訊息

測試寄信至 yahoo.com.tw

收到的退信訊息

要縮短測試時間可以這麼作

postconf -e ‘maximal_queue_lifetime = 1d’
postconf -e ‘delay_warning_time = 0h’
postconf -e ‘bounce_queue_lifetime = 1d’
