I am running Exchange 5.5 behind a proxy server (2.0). When I try to send e-mail out the message gets stuck in the IMS queue. It states that the host is unreachable. We are getting emails in fine.

Any insight to this would be appreciated.

Check and see if you can resolve DNS names from that computer. If not check into the DNS settings.
