各位版主、高手：
       我最近一直有类似的退信通知，我看了说明也找不出原因，到服务器上看了发信过程，也找不出原因，请教哪位高手能帮忙查找一下原因啊，谢谢了!以下是退信通知：


The attached message had PERMANENT fatal delivery errors!

After one or more unsuccessful delivery attempts the attached message has
been removed from the mail queue on this server.  The number and frequency
of delivery attempts are determined by local configuration parameters.

YOUR MESSAGE WAS NOT DELIVERED TO ONE OR MORE RECIPIENTS!
