已经设置过服务器不中继邮件以及SMTP需要验证。但在日志中仍然查到有以下中转邮件成功的记录，请教一下是什么原因。应该如何设置才能避免出现此情况？
为什么不能做到只要发件人不是本地域，就直接取消此邮件的传递过程呢？

可能是對方有你的服務器需要的SMTP的驗證帳號和密碼。

噢。谢谢指点。

不过接下来的问题是，如何才能查到对方当时发这封邮件时使用的已验证的SMTP帐号是什么呢？

前几天我也碰到这个问题，不知道怎么解决，问题是我只设置了一个邮件账号，还在测试阶段，晚上12点多的时候，我就发现有1万多封中继邮件，不知道他们是怎么发的,中继我都关了，都是需要认证的。很奇怪啊，，，，，，如果楼主找到原因了，麻烦说下哦
