为什么我的邮件服务器不能发给外部邮箱发邮件(如SINA)？ <br>
可以接受外部邮箱的邮件.<br>
内部邮件收发都可以，大侠们帮忙呀！十万火急！！！ <br>
用的软件是MDAEMON6.84 <br>
<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!
