无法使用 Postfix 接收电子邮件：状态=延迟（接收初始服务器问候时与 127.0.0.1[127.0.0.1] 的对话超时）

大约一个月前，我一直在设置服务器，但因为个人原因不得不停止。今天我又回去尝试发送/接收电子邮件。

最初，我从我的 Gmail 帐户向服务器上的电子邮件帐户发送了一封电子邮件，并成功收到了该邮件。但是，当我回复该电子邮件时，我的 Gmail 帐户中没有收到该邮件，服务器上的电子邮件帐户中也没有收到退回的邮件。

但是，我又尝试了两次从 Gmail 帐户向服务器发送电子邮件，但都没有收到。我还一次又一次向 Gmail 帐户发送电子邮件，但既没有收到邮件，也没有收到退回邮件。

我检查了 Postfix 邮件队列，它显示以下信息： 在此处输入图片描述

我还检查了邮件日志，并收到以下错误：

May 16 15:58:43 setanta postfix/smtp[9231]: DC06A122: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=1542, delays=1242/0.01/300/0, dsn=4.4.2, status=deferred (conversation with 127.0.0.1[127.0.0.1] timed out while receiving the initial server greeting)

有人知道这是怎么回事吗？

提前谢谢了！

答案1

您正在向 postfix 预计在端口 10024 上运行的服务发送邮件。

该进程未监听端口 10024；也许它没有运行？
