最近公司邮件怪问题高手帮帮

广州公司邮件服务器EXCHANG　2003　以前都可以正常发送邮件到合肥公司。最近几天都发不出去，但发其它外部邮件都没问题。

ping mail.ccllabel.cn　得到的结果是
C:\Documents and Settings\Administrator>ping mail.ccllabel.cn

Pinging mail.ccllabel.cn [220.178.44.91] with 32 bytes of data:

Request timed out.
Reply from 61.190.195.145: Destination net unreachable.

    Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),

220.178.44.91这个IP才是合肥的邮件IP　
用别的MSN给合肥发邮件又可以收到，发送到合肥的邮件还在广州服务器的邮件队列里面。状态"The remote server did not rospond to a connection attempe"

请高手帮帮一下，谢谢

Destination net unreachable
－很明显是网络出问题了。61.190.195.145是你的网关IP吗？回想一下是不是和220.178.44.91之前的路由出问题了。
