===================
   感谢wxhsh的热情,  上周六时路由器接口上多加了个IP,结果这个IP是有问题的,去掉它恢复之前正常情况.

应该是IP被拒了，以下是我连接的信息：

220 mail.irf.com ESMTP
ehlo test.com
250-mail.irf.com
250-8BITMIME
250 SIZE 104857600

原因基本相同，也是IP进了黑名单。

我在 http://www.dnsbl.info 查了一下,我的IP只进了这个:blackholes.five-ten-sg.com
再进入查,提示:
IP address xxx.xxx.xxx.xxx is listed here as china spam.
On a *very* small mail server with only a few users, none of whom know or communicate with anyone in China, we are currently receiving more than 1400 spam messages per day from Chinese address space. When that enormous flow of spam stops, we may consider allowing email from Chinese ip addresses again. Until then, you will need to use some other communication path.

added 2001-04-19; china does not seem to care about spam
added 2001-04-20; we do not accept mail from china

===========这小子是不是对中国有歧视!?

wxhsh

有时是会整段整段封中国IP，但通常是阶段性，另外，如MX记录做得不合法，ehlo值不正确等也会被列，不过好象对我的邮服IP还比较友善，下为偶的截图：

被列入到一个中:

wxhsh

与LZ PM后找出原因，还是邮服出IP与MX记录IP不一致造成的原因，实际外发IP被列多个黑名单中，LZ重新NAT后解决。
