[求助]关于James邮件服务器不能向外网发送邮件的问题

((()))

James配置：
dnsserver配置为ipcinfig -all出来的dns.

我用outlook发邮件的时候，可以向QQ邮箱发邮件。但是不能向163的发。下面是mailet的log:

ps:那些没有发送成功的邮件每服务器一启动就开始尝试连接到163的MX发送。在哪里可以配置管理这些邮件呢？
请高手来指教啊。。。

I sent mails to 163.com successfully with the same configuration yesterday,but I don't know why the reason is.
