我有一台Apache服务器，在过去的几年中一直很高兴地发送邮件 – 本周早些时候，postifx发送的所有邮件的发件人地址都发生了变化，结果99％的邮件被反弹或标记为垃圾邮件。

我不知道服务器或DNS发生了任何变化，但电子邮件正在被反弹和列入黑名单。

在我的maillog中，我有两个相隔7分钟的消息 – 第一个是罚款，并被发送，但一切后来反弹：

主要区别在于，从地址已经从[email protected]更改为apache.domain.domain，并且domain.com已更改为仅域：

• testing一个邮件服务器
• Windows DNS服务器导出
• VMware ESXi：DNS中的dynamic注册失败
• 我无法获得https://sendsonar.com的工作，但是sendingonar.com和https://www.sendsonar.com工作正常
• CoreOS集群DNS设置

任何想法可能导致这一点，更重要的是，我该如何解决这个问题？
