关于域名ping问题

Ashitaka

对方域能发送邮件到公司域,在公司内ping不通对方,也找不到ip,在外网也不行.
ping 了以后返回以下信息"Ping request could not find host gbmgroup.com.cn. Please check the name and try
again."

有可能对方在路邮器、firewall  禁止PING 的功能。

砸锅卖铁

gbmgroup.com.cn这个域名是存在的(有MX记录，但没有A记录)，你应该ping对方的主机名或IP地址，如果对方禁止Ping那也是ping不通的

gbmgroup.com.cn MX preference = 10, mail exchanger = gateway10.gbmgroup.com.cn
gbmgroup.com.cn MX preference = 10, mail exchanger = gatewaymx10.gbmgroup.com.

gbmgroup.com.cn MX preference = 20, mail exchanger = gateway20.gbmgroup.com.cn
gbmgroup.com.cn MX preference = 20, mail exchanger = gatewaymx20.gbmgroup.com.

gbmgroup.com.cn MX preference = 30, mail exchanger = gateway30.gbmgroup.com.cn
gbmgroup.com.cn MX preference = 30, mail exchanger = gatewaymx30.gbmgroup.com.


有6个MX.
你不应该不ping对方, 而应该"telnet 对方mx服务器 25"

c:>telnet gateway10.gbmgroup.com.cn 25
220 hjgbmgateway.gbmgroup.com.cn Microsoft ESMTP MAIL Service, Version: 6.0.3790

能telnet并看到对方的服务器信息.
