还有这种错误提示，在服务器上都找不到相关的日志记录，都是什么原因，是出在我们这边服务器，还是对方服务器？？？？<br>
各位路过的帮看下。。。<br>

一起走

帮顶，不过我是直接联系对方技术员帮解决的。<br>
现在还有传21CN的邮件有点问题，如果谁有解决方法麻烦通知一声

mrbing

第一个问题我估计是由于这里：<br>
Tue 2005-11-08 17:54:33: Socket connection established (192.168.0.102 : 4348 -> 220.181.31.189 : 25)<br>
建立连接时用的是内网IP，而这里Tue 2005-11-08 17:54:33: --> EHLO mail.toplight.net与远程连接时用的是mail.toplight.net，对方的DNS查询对应不到192.168.0.102，可能是连接被拒绝了。<br>
不知道对不对，纯属个人意见。<br>
<br>
<font color="red">刚想了一下,第一个问题应该不是内网IP的问题.(11-11 9:56)</font><br>
<br>
第二个问题：<br>
附加的邮件已“永久”递送失败!<br>
<br>
经历了多次的递送失败之后, 邮件中的附件, 已从服务器中移除。<br>
试图递送邮件的频率和次数,<br>
都根据本地端的配置参数所决定。<br>
<br>
你的邮件无法递送!<br>
<br>
多数是由于DNS查询不到目的地的MX记录，重试一定次数后失败退信。多是由于DNS不稳定造成的，建议更换一个DNS作为主DNS。象深圳这里我原先用深圳的DNS 202。96。134。133，也出现了这个退信，后来查找日志后发现是<br>Tue 2005-11-01 00:12:47: [xxx.net]的 MX-record 解析已在进行(DNS 服务: 202.96.134.133)...<br>Tue 2005-11-01 00:12:52: 名称服务器报告域名未知<br>
<br>
后来换成广州的DNS202.96.128.68就好了。<br>
202。96。134。133在作nslookup的时候就要查好几次才能查出来，应该是不稳定。<br>

希望对你有帮助。

那么，是否意味着不能通过内网IP连接服务器发送邮件？

taotao

有同样情况，帮你顶！

mrbing

再想了一下，中继都已完成了，怎么会出错呢，可能是对方拒收
