POSTFIX 无法启动提示:绑定 0.0.0.0 端口 25:地址已在使用中

抱歉,我已阅读了大量相关主题,但没有找到针对我的问题的解决方案。

今天早上突然 POSTFIX 没有响应。我没有在服务器上进行任何特殊操作。

POSTFIX 状态显示:

说端口 25 已经在使用但我找不到是谁使用的?

我的服务器上未激活 sendmail。

netstat -lnp |grep :25

不返回任何内容

我尝试重启服务器。没有进展。

请帮忙!

答案1

您似乎正在尝试在不同的 IP 地址上运行不同的 TLS 证书。您已配置为使用不同的 TLS 证书master.cf来应答特定 IPv4 地址的smtp和端口。submission

但是,您还保留了原始smtp行,出于某种原因,该行设置为调用postscreen。此行触发错误。它无法绑定到 INADDR_ANY,因为特定的 IP 地址侦听器已绑定。这就是您收到错误的原因。而您在或输出Address already in use中看不到任何内容的原因是因为 Postfix 退出并且地址未绑定。netstatlsof

您应该将那一行注释掉master.cf
