SMTP queing up in exchange server 2003

I am running Exchange Server 2003 on Windows server 2003 and over the last few days noticed that mail just stopped flowing out. Mail is coming in fine but not going out. If i re-boot the server the mail is sent but then after about 10 minutes stops again. I have checked a few of the posts on experts exchange and some suggested it may be relaying. I have checked this but it isn't. Can someone please help me overcome this issue as i have now run out of ideas?

Thanks

Try increasing the SMTP logging. This may give you an indication on what's going wrong.
You can increase the logging on the properties of your Exchange server (in Exchange System Manager). Select Diagnostics Logging tab and set MSExchangeTransport / SMTP Protocol to Maximum.
If you have a busy Exchange server, beware that this new logging can fill up you Application Log quite quickly...

I have just had it resolved. The problem was down to DNS which couldn't resolve our other exchang server.

Thanks

Well, that's what the logging could have told you too ;-)
Glad you solved it.
