关于域名ping问题
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。 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 c:\>nslookup
>set type=mx
>gbmgroup.com.cn
Server:FJ-DNS.fz.fj.cn
Address:218.85.157.99

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
