We have exchange 5.5 that will receive email fine but, sending internet email (connected directy to the internent) just stays in the 'outbound messages waiting delivery' queue. I have seen a checklist from microsoft but can't remember where its at. Any suggestions?

Are you delivering messages to a Host or are you using a DNS for delivery? Verify that you can see either from your SMTP server. If using DNS verify the proper DNS IP address in the TCP properties of your Network Card.

Is there a firewall betweenyour SMTP server and the Internet/ISP? If so verify that PORT 25 is open in both directions.

If the above are both good and this had worked previously, then you may have a message in your outbound queue which is corrupted. You can verify this by shutting down your IMC services, and mvoing the contents of the Exchsrvr\IMCDATA\OUT directory to another location. restart your IMC service and send a message, if it goes through then you have a corrupted message in the queue.

If non of these areit then you may wish to visit the online Technet and search for IMC:

Good luck
