请教各位DX，关于MAILER-DAEMON退信的含义

coolfish

下面是我的qmail服务器里的一封退信，发到MAILER-DAEMON邮箱的。

我没有jack这个邮箱，同时加了smtp认证，但是这份信的意思好像是说从jack@abc.com.cn的信已经发出了，被退回什么的。

是我的系统出问题了吗？

Hi. This is the qmail-send program at mx2.proxad.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

abc.com.cn是我把原来的域名更换了.
看最后的一段,这封信也不是通过我的smtp发出的,是不是这封信根本就是从其他的服务器发出的.但是为什么会用到我的域名?
难道仅仅是巧合?
