How about solving this error.

SembeeCommented:
Crystal ball is still on the blink...

You have left out all of the key information...

Exchange version and service pack?
Windows version and service pack?
What else is installed on this machine?

Are there messages stuck in the queue?
Is this a one off error, or reoccurring regularly?
Any patterns?

We can only work with what you have given us, and at the moment that is nothing whatsoever to go on.

Ok Simon. Exchange server 2003 with service pack 2 on windows server 2000. It has only exchange installed. This started just a month back. The queue shows 10 messages stick and retrying to send to a domain mboxx04.com.  Seems to be a chinese website. Do not know how to track the machine casuing this problem.
Thanks

It looks like a straight connection error.
Chinese stuff is always suspicious.

It could be a form of relaying - either authenticated, NDR or straight open relay. You will need to check for all three.
If you are relaying messages they normally show up in the queues.

As you are on Windows 2000 I can't really recommend enabling recipient filtering as it opens you to a dictionary attack.

Turn on Message tracking and see if the messages are coming from inside or outside.

Sorry Simon, little raw with a couple of new issues. Where do I find the message tracking option and what happens if I find something there, or will I find something there?

SembeeCommented:
Message Tracking only shows you what is happening, so you will not actually be able to do anything from there.

What it does is show what Exchange is doing with the message. It is evidence gathering stage, not problem fix. Without the evidence you will not know what the source of the problem is.
