您需要返回并重新阅读您的错误消息。

说明了一切。您的邮件服务从一开始就运行不正常。
请记住，SysV 初始化脚本状态管理， 不是流程管理。状态管理处理系统的状态；进程管理是状态管理的一个子集，只关心对长期运行的进程的监督。
完全可以“启动”该服务，SysV 会将该服务标记为正在运行，但该服务将停止运行。因此，现在该服务处于“运行”状态，但实际上并未运行。停止该服务，然后启动它，然后查看日志：
/etc/init.d/postfix stop ; /etc/init.d/postfix start ; tail -f -n100 /var/log/messages
查找有关 postfix 启动的消息以及它正在做什么。在此处发布一些结果。
