exchange is up but no emails go in or out

Basically our OS is small business server 2003, and right now I can connect to exchange, the services are up, no error logs.  I can remote connect to the server, but I cannot and nor can anyone else in the company can send or recieve emails.  Yes also the proper services are started and I did restart the router service and rebooted the server.  Any ideas as to what I should do?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Sorry to here about your problem.  Can I ask when you say send and recieve is that to users on the same server or to external addreses??
