SMTP Loop 4.4.6 after exchange server crash

I had a network that was running two servers, a Small Business Server 2003 (was first server) and also a Server 2003 Standard server that is running exchange.  All the mailboxes were on the Server 2003 Standard computer.  The only thing the SBS server was doing was POP3 connector and mail routing.  The other day the SBS server crashed and was un-salvagable.  I have gone through all of the steps to completely remove the SBS server from the organization, including seizing FSMO roles, and removing all references to the server in DNS/Active Directory/Exchange.  Since that server has gone down, no user on the exchange server can send mail to anyone outside the exchange organization.  Internal mail works correctly, and they can receive all emails sent from the outside world.  When a message is sent, I see a queue created for the destination domain, but the mail gets put into the 'Messages queued for deferred delivery' queue, where it sits until it is deleted and a NDR is sent.  Have ran Exchange TA and Exchange BPA and corrected any problems.  Exchange TA just fails and says there is a loop.  When i track the messages, the server keeps forwarding the mail to itself continuously, but i cannot figure out how to stop it.  I tried running the internet mail setup wizard, but no luck.  Been searching for hours with no luck
