发送邮件到internet时,有时可以有时不行

[libj]

发送邮件到internet时,有时很快可以收到,有时要过很久才能收到或者邮件被退回;接收外部邮件没有问题,
查看mailbox中的邮件状态是等待发送,以下是出错信息:

02/08/2006 10:45:34 AM Router: No messages transferred to XXX.COM (host mailgate.XXXX.COM) via SMTP: The remote server is not a known TCP/IP host.
02/08/2006 10:45:34 AM Router: No messages transferred to XXX.COM (host mailgate1.XXX.COM) via SMTP: The

02/08/2006 11:06:48 AM Router: No messages transferred to ZHONG-YING.COM (host ms.ZHONG-YING.COM) via SMTP: The remote server is not a known TCP/IP host.

dns 服务器的解析没有问题.

多谢大家回复和帮助

通常情况下，出现"The remote server is not a known TCP/IP host" 的问题，是因为对方的服务器无法连通，如果排除已方的网络问题，则更多时候是对方的主机连不上。
