维护Postfix的一些脚本、程序集锦
作为一名Postfix的管理员,维护Postfix的正常运行,并随时排除故障,这是最基本的任务。本文提供了一些我自己写及平时搜集到的脚本和程序,以便实现自动化的维护和操作。包括自动清理日志,分析日志,自动增加用户等等。

Here's my own /etc/periodic/daily/460.status-mail-rejects script,
and yes it needs updating when logging formats change.
This script will not show rejected mail when the client never
returned after a soft (450) error code from the server. I use 450
for non-FQDN HELO hostnames, so that I can whitelist mis-configured
sites that aren't spammers.
