我们的 postfix 系统在晚上停止发送邮件。每天晚上 2 点，它都会停止接收邮件。该服务器是一个监控服务器，每天发送大量邮件。/bin/mail 将邮件放入 postdrop 队列，postfix pickup 会在那里接收邮件，然后 postfix 会处理邮件。它整天都在工作，但在凌晨 2 点它停止了，日志中没有任何内容（即使启用了接收和清理的详细日志记录）。当我手动重新启动 postfix 服务时，它开始从 postdrop 队列中传递邮件。凌晨 2 点会发生什么，导致 postfix 停止工作？cronjobs 不会影响 postfix

为了解决这个问题，我们编写了一个脚本，每天晚上 3:30 重新启动 postfix
postfix_restart.sh：
mailcount=`/usr/bin/find /var/spool/postfix/maildrop/ -type f | /usr/bin/wc -l`
if [ "$mailcount" -gt "3" ]; then
/bin/date > /tmp/mailTEMP.txt
/usr/sbin/postqueue -p >> /tmp/mailTEMP.txt
echo "Queue maildrop: " >> /tmp/mailTEMP.txt
find /var/spool/postfix/maildrop/ -maxdepth 1 -type f | wc -l >> /tmp/mailTEMP.txt
/sbin/service postfix restart >> /tmp/mailTEMP.txt
/bin/cat /tmp/mailTEMP.txt | /bin/mail -s "Postfix restarted" [email protected]

答案1
它是一个 CentOS 5.11 服务器，我们的存储库（CentOS 标准存储库、epel、FAN、graphviz 和 remi）中没有可用的较新的 postfix 版本。
所以你被困在不受支持的 Postfix 2.3.3 版本中。好吧，我理解你的情况，这真的很悲哀 :(。
Postfix 2.3.3 版本于 2006 年 8 月发布。尽管 CentOS 团队为该版本移植了几个功能，但仍然可能缺少一两个错误修复。
我的建议是请尝试升级它。也许通过其他非官方仓库或从源代码构建。另一个选择是将此错误发布到 CentOS 邮件列表上。
并且我认为甚至 Wietse Venema (postfix 的作者) 也会建议您升级它。看门狗超时并不是 Postfix 邮件列表中经常出现的问题，这一事实本身就表明问题很可能出在 Postfix 之外
