DNS服务器重新设置了N遍了！
官方上说的有可能出现有问题都试过了，但用邮件客户可以发送邮件，就WEB方式就不行！请问要怎么设置？

请大家帮帮忙，如果没有办法，哪只有准备换邮件服务器，但不知道什么邮件服务器软件好，希望大家给点参考意见！

有可能是防火墙的问题，也有可能是装瑞星给整的。

就WEB方式就不行?如何不行，出现了什么问题？是否有系统退信
能否描述下你的邮件系统构造（WINWEBMAIL版本，防火墙软件，杀毒软件等等情况）
WINWEBMAIL设置起来还是比较简单的
相信只要有点耐心就可以找到问题的所在

服务器系统:WINDOWS2003 VOL中文版
防毒软件:mcafee企业版8.0i中文版
WINWEBMAIL版本为:3.6.3.1企业版
DNS设置为:202.96.209.133
防火墙没有安装

使用sohu和hotmail给该系统发信可以收到。
用该系统WEB方式发信给sohu和hotmail，系统退信信息为“邮件发送超时”
通过邮件客户端发信对方可以收到！

退信内容是什么？贴上来大伙看看。

以上就是发到SOHU和HOTMAIL的退信内容！

看出错信息，DNS是解析到了，就是server没法连接到目标服务器的25端口，可能是防火墙禁掉了对这些地址的连接。重启服务了没？
