大概架构如下:
域名是在中资源申请的域名,A/MX记录已经在中资源做过解析,解析正常。ping域名及返回的IP均正常

内部e-mail server 映射到公网IP。在路由器上开放25,80,110端口。telnet  *.*.*.*  25/110均 正常。

服务器是用ubuntu 10.04  64位操作系统,安装了iredmail。下面是简单配置,请各位大侠给予帮助,

小弟已经研究几天了,快崩溃列。主要问题是:对外网能发不能收,内网收发正常,先谢谢各位了。

弱弱问下:我没有配置SPF和DKIM记录。不知是否会有影响?

         这边映射的公网IP是否需要ISP提供商做反解析?   

       谢谢各位大侠了、、在线等。。。
