往exchange做服务器的邮箱发送信件时却被退回？？
我用mdaemon做服务器，但往exchange做服务器的邮箱发送信件时却被退回来。信息如下。。<br>"The attached message had PERMANENT fatal delivery errors!<br>
<br>
After one or more unsuccessful delivery attempts the attached message has<br>
been removed from the mail queue on this server. The number and frequency<br>
of delivery attempts are determined by local configuration parameters.<br>
<br>
YOUR MESSAGE WAS NOT DELIVERED TO ANY OF IT'S RECIPIENTS!<br>
<br>
Failed address: xxx@xxx.com<br>
<br>
不知道为什么。？<br>
请帮忙。。<br>

地址是否正确？检查Exchange Server的SMTP设定。
