发件是否使用中继，对方好象验证出ESMTP用户与FROM不一致。

nfore

我的MD不允许中继啊，SunT@xxxxxx.cn就是我MD的用户

wxhsh

并非你服务器不允许中继，而是你发件是否使用了中继进行发送。CHECK THIS：

确认没有使用这个。

nfore

我选的是第三个：“总是把所有外送的邮件直接发送给接受者的邮件服务器”

wxhsh

仔细看了一下，知道什么原因了。
对方邮服只是个IIS自带的ESMTP发送服务，所以它以为你要通过它中继，因此拒绝了你。

nfore

如何避免这种情况的情况？再说我也不想中继它啊，如何解决？谢谢

wxhsh

对方的问题，我发过去都被退，他们肯定解析错了邮服地址。
