一些邮件提供商拒绝我的邮件

我最近搬到了一台新服务器，现在我的一个用户抱怨电子邮件无法到达收件人。邮件日志告诉我他们拒绝了这封邮件

AOL will not accept delivery of this message. (in reply to end of DATA command))

refused to talk to me: 421 mtaig-mba02.mx.aol.com Service unavailable - try again later

Recipient address rejected: aol.com (in reply to RCPT TO command))

最后

(host mailin-03.mx.aol.com[64.12.91.196] said: 521 5.2.1 :  (CON:B1)  http://postmaster.info.aol.com/errors/554conb1.html (in reply to end of DATA command))

现在我不确定，我的 postfix 配置是否存在问题，或者我的主机托管商是否为我分配了一个“声誉不好”的旧 IP 地址，而这并不是我的错。

这就是我当前的 main.cf 的样子

有任何改进建议或想法吗？哪里出了问题？

答案1

AOL 发出的错误消息似乎表明您的 IP 地址确实被阻止了。

您可以尝试使用在线数据库进行检查，例如发件人基础如果您的 IP 有列出的声誉。

不幸的是，由于禁止的性质，您无法采取更多措施来解决这个问题，只能尝试向相关提供商（在本例中为 AOL）提出上诉，并解释自从他们禁止该 IP 以来，该 IP 已易手。

作为一种肮脏的快速修复方法，如果您有另一台服务器，您也可以使用它有选择地中继发往 AOL 的邮件，这样它就不会显得来自被禁止的服务器。
