但是跟网易、新浪、雅虎等邮局收发都正常的。是不是我的邮局设置有问题，还是DNS解析有问题。另外TELNET AFRICAONLINE.COM.GH 25 也不通。
各位大侠，我是个新手，请帮一下，小弟不胜感激。

应该是ＤＮＳ的问题，我查询出的结果如下：
africaonline.com.gh     MX preference = 10, mail exchanger = mx2.africaonline.co
m.gh
africaonline.com.gh     MX preference = 30, mail exchanger = mx1.africaonline.co
m.gh

mx2.africaonline.com.gh internet address = 212.85.196.3
mx1.africaonline.com.gh internet address = 212.85.196.5

是我的DNS解析有问题吗?有没有可能是我的防火墙设置有问题?

我使用的是第三方的防火墙,需要开哪些端口

参考下图：

但ＳＭＴＰ外发ＴＣＰ源端口是随机的，目标端口25，要注意下。

上面的端口已经全开了，还是一样。把防火墙的级别调低就行，我用的是瑞星防火墙。但ＳＭＴＰ外发ＴＣＰ源端口是随机的，目标端口25，要注意下，这个应该怎么设置？
