请教这里高手. 公司的公网地址变了, exchange有些域名的地址不能发送
公司的公网地址变了, ISP那里新地址解析已做好。MX 记录也填了新的IP 地址.现在的问题邮件都能收.发也可以. 就是有几个域名地址,老是发不过去, 返回错
误.有国内的,也有国外的。也不是很多,就这几个地址.没改IP地址前都好的.老
板很急. 请问这种情况主要是问题出在哪?谢谢.
请问那几个用端口映射还是直接用公网IP-NAT
你可以先PING一下那几个..看一下是什么情况.[ 本帖最后由 xlas 于 2007-11-26 08:30 编辑 ] 你解析一下对方的地址,你发的发不出应该有退信的,看退信是什么内容,最好把退信内容贴上来
谢谢楼上的提醒, 我就把一些报错信息贴在下面, 主要都是发往国外的有问题.

因为关系公司信息, 我把地址都改掉了.域名反向解析做了, 我查了下,但还没生效. 如果在你的邮件服务器上telnet对方25端口成功的话,有可能是你新的地址没有做反向解析;如果telnet不成功,那就是网络问题,有可能路由不可达,有可能端口被封 感觉网络有问题,这个信息只是告诉你邮件被delay了,而不是发送失败。
