[Mail] 邮件路由问题???

[weixin_38066087]

各位大虾,帮帮忙!!我这里的邮件服务器为domino6.0.1CF1,准备由Suselinux移到windows2000上,配置IP都一样,移后,发现利用POP发信可以,但收信失败,由外部的邮箱向本地发信时,信被退回,error信息如下:
because:

  Error transferring to ITTEC.COM.CN; Maximum hop count exceeded.  Message probably in a routing loop. Maximum hop count exceeded.  Message probably in a routing loop.
