什么系统？你的邮件服务器可以发向其它的地址吗？<br>

CoreMail！发往国内的都没有问题！发往国外的时好时坏！

通过测试发现magnecomp.com域名可以发送信件的,查看退信的内容,应该是你发送的地址有问题.或者是转发地址<br>

我确定我的邮件地址没有问题!因为在这封邮件前后都能成功发送!
而且经常发生类似的问题:
> The message to XXXXX@kaifa.com.hk is bounced because : SMTP error, RCPT TO: 551 User not local; please try <forward-path>
>
> 你发送到XXXXX@kaifa.com.hk的邮件由于以下原因被退回 : SMTP error, RCPT TO: 551 User not local; please try <forward-path>

象上面的这个问题是,我发给kaifa.com.hk两个人,其中一个有退信通知,之后打电话对方说他的绝对没有任何问题.

不知道是什么原因造成的!请大家指教一下!

好感动，楼主真是有心，一年多的帖子一直在研究。
关于551 User not local; please try的问题，最近两周又出来了。是GFW的关系。你可以看一下：
