无法收外部邮件。
我们公司使用的是exchange server 2003前天突然不能收外部邮件
内部邮件收发正常，也可以向外网发邮件，可就是无法收外部邮件，所有的都被退回。
126退信提示：
你发送到
jswrj@******.com的邮件由于以下原因被退回 :
jswrj@******.com SMTP connect error
请到
http://help.163.com/special/0075 ... hdrawal_letter.html 查询退信原因。
我们exchange server 2003 与DNS，内网网关分开，使用KerioWinRouteFirewall 6进得管理。
前天我有对KWF进行修改，也不知道是否是哪里改错了，
用TELNET连接110端口可以连得上，可是连25端口就连不上。
dcdiag 测试如下：
C:\Documents and Settings\administrator.********>dcdiag /n:********.com

是不是我的KWF出了问题？
