看起来我们已经大约9天没有收到邮件了

这导致我们的退信通知没有进来，并引起了 Amazon SES 的问题。我正在尝试了解为什么 POP3 没有收到邮件，据我所知，它的配置是正确的，并且该帐户似乎运行正常，我可以从外部连接等。

欢迎任何建议。

谢谢！

请帮我处理一下这个

如果我输入所有信息都正确，响应是空的，如果我输入错误的密码，则会收到错误，所以看起来没问题。

如果您使用邮件客户端连接，您会看到多少封电子邮件？

在我的例子中，我禁用了删除旧邮件的功能，并且由于队列中的邮件过多而超时。  
将已处理的邮件移至存档后，超时消失了。

我不得不进去删除所有存档的电子邮件，哇，谢谢，这奏效了
