环境如何配置的呢..

ad+exchange 2003,

钉子

收不到邮件一般要检查：
１．域名解析－－－是否正常进行ＭＸ解析．
２．防火墙设定－－－是否打开ＳＭＴＰ端口．

不知道kitchentrend.cn是不是你真实的域名，我用http://www.5dmail.net/tools.htm　中的DNS报告　查出你的mx记录是 mail.kitchentrend.cn,然后我试着telnet　 mail.kitchentrend.cn 25好像不通．

我在防火墙墙上做了开放出了110和25 ,原来是可以的,不知道现在为什么就不可以了,我是在上挂了两个域名,

终于解决了,是端口开放有问题,
