在服务器手动连接126的smtp服务器失败,但是奇怪,同一网段的DNS server上却可以连接到126的smtp server.信息如下:
C:\Program Files\Support Tools>telnet smtp.126.com 25
Connecting To smtp.126.com...Could not open connection to the host, on port 25:
Connect failed
防火墙上:ex-->internet 开通25端口,internet-->MIP ex server的25端口开通所有服务,应该不是防火墙设定的问题吧?
如果是DNS问题,应该不能ping通smtp.126.com吧?可是在ex上却可以ping通,信息如下:
C:\Program Files\Support Tools>ping smtp.126.com
