SMTP Email Being Held


We have a Windows 2003 SBS runnning Exhange. For some reason our external email is not being sent out. It sits in the queue as 'Message Queued for Remote Delivery' and does nothing else.

After about 12 hours we get an email from the server telling us that it has not been delivered.

It was working yesterday, but not today and after a server reboot we stilll have the problems.

Any ideas?
