我最近搬到一个新的服务器，现在我的一个用户抱怨电子邮件没有到达收件人。 邮件日志告诉我他们拒绝邮件
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

现在我不确定，如果我的postfixconfiguration有问题，或者我的主机分配了一个旧的IP地址“不好的名声”，这不是我的错。
这是我目前的main.cf的样子

任何改进build议或想法出了什么问题？
来自AOL的错误消息似乎表明您的IP地址确实被阻止。
如果您的IP具有列出的信誉，则可以尝试使用在线数据库（如senderbase）进行检查。
不幸的是，禁止性的做法是你不能做更多的事情来解决问题，而不是试图呼吁相关的提供者（在这种情况下，美国在线），并解释说，这个知识产权已经被禁止了。
作为一个肮脏的快速修复，如果你有另一台服务器，你也可以使用它来有select地中继到AOL的邮件，以便它看起来不是来自被禁止的服务器。
