更换外网IP以后，Imail发送总是有2-4小时延时，甚至会退信
请教大家，这是为什么呢？接收所有信件都正常，但就是发送不正常，总有延迟，甚至丢失。
从Log看挺正常，但就是延迟甚至外部收不到。我们从网通变到科技网以后就有这个问题了，我们其他的设置（防火墙、路由等）除了外网IP变了，其他都没变。
我们的域名指向也都改了3、4天了（MX指向，A记录指向都改好了）

[ 本帖最后由 weidbl 于 2007-6-1 11:09 编辑 ] 再找一个你认为延迟的邮件。看日志中有没有其它记录。 谢谢管理员,我这边的情况是全部邮件的发送都是延迟的,不分地址;但接受完全正常.
不知道有什么原因会导致这个情况.
