![伪造自 Exchange 服务器的电子邮件](https://linux22.com/image/660533/%E4%BC%AA%E9%80%A0%E8%87%AA%20Exchange%20%E6%9C%8D%E5%8A%A1%E5%99%A8%E7%9A%84%E7%94%B5%E5%AD%90%E9%82%AE%E4%BB%B6.png)
我的一位 Exchange 用户收到了一封被退回的电子邮件。他们没有发送这封电子邮件,我有点不明白他们是怎么收到这封邮件的。我查看了日志,没有看到电子邮件离开我们的服务器。所以我想这很好,没有开放中继。然而我仍然有点担心。
如果这不是来自我们的服务器,我该如何防止这种情况发生?
这是标题。我保留了原有的所有内容,但做了以下更改。
mailserver.outdomain.com(是我们的服务器名称)
[电子邮件保护](确实有我们的真实域名)
PARIS FENTON(确实有一个有效的用户电子邮件,Paris Fenton 不是用户名,但在原始标题中)
