我有一个运行Postfix的iRedMail服务器，并试图确定其垃圾邮件问题的来源。
我已经改变了域名上的MXlogging接收垃圾邮件的地址，好消息是没有垃圾邮件通过这个第二台服务器。 但是，尽pipeMXlogging发生了更改，但新的垃圾邮件仍会出现在旧服务器上。 这怎么可能？
以下是其中一封垃圾邮件的标题：

这里是我的/var/logs/mail.log文件的一部分

我也认为可能有一个PHP脚本发送这个邮件的地方，所以我安装并运行了Linux恶意软件检测，但没有发现任何东西。
谢谢你的帮助！

此电子邮件来自您的服务器之外，从指定的IP地址。
Postfix被configuration为将其传递给Amavis进行病毒扫描，当完成后，Amavis将其传回给Postfix进行传送。
这就是为什么有两个localhost Received：行。 一个是Amavis在处理消息时添加的，另一个是Postfix从Amavis重新接受它的最终交付。
