用户存在，我已经说明了，只是有的时候会出现这个问题，今天好像又没有问题了，不知道什么意思，到底是哪里的问题呢？哪位大虾知道，给个说明。

Numeric Code: 5.3.0

First Available: Exchange Server 2003

Possible Causes: Exchange Server 2003 has a feature that permits Exchange 2003 to operate without the Message Transfer Agent (MTA). If a message was sent incorrectly by using the MTA route, this delivery status notification is returned to the sender.

Note Although Exchange 2003 can operate without the MTA, Microsoft does not recommend or support this configuration.

To turn on this feature and to prevent the messages from queuing to the MTA, follow these steps:

1. Disable the MTA service.  
2. Set the DWORD value to 0 in the following registry subkeys for every information store database and public folder store:
HKLM\System\CurrentControlSet\Services\MsExchangeIS\<Server Name>\<PrivMDB_GUID>\Gateway In Threads

HKLM\System\CurrentControlSet\Services\MsExchangeIS\<Server Name>\<PrivMDB_GUID>\Gateway Out Threads
When you do this, you are making store resources that are associated with MTA delivery available.
3. Restart the information store.
Troubleshooting: Check your routing topology. Use the WinRoute tool to make sure that the routes are correctly replicated between servers and routing groups.

user unknow我想应该是对方服务器的问题, 可能是后来对方管理员把问题解决了.

elaying+denied.+Proper+authentication+required.  这个问题估计是对方管理的中继配置错误, 或你的邮件被对方拒绝.

最好能先查一下你的邮件发送IP是否有被反垃圾组织加入到黑名单里.

Look4Dream

反垃圾黑名单问题我很早就查过了，早已经解决。
我也一直怀疑对方的邮件设置问题，或者对方使用了智能网关之类的东西，没有设置清楚。问题就是出在有时候可以通，有时候不能通，真是郁闷！搞得我用户一直抱怨多多，把责任推到我得头上，说是我们得问题。
请教还有没有更准确得解释，或者该如何排除呢？
