Exchange Server Not Transferring Messages

We're currently undergoing a project to migrate from stand-alone to blade servers. To move exchange,I've installed exchange on the blade, so now running two Exchange 2003 Servers on Windows 2003 servers, same subnet, physically connected to the same switch, etc.

I've moved two mailboxes to the NEWMAILSERVER as a test, and am experiencing the following:

1.) Mailboxes on NEWMAILSERVER can send outside e-mail, mail to mailboxes on NEWMAILSERVER and OLDMAILSERVER both.

2.) Outside e-mail going to the mailboxes on NEWMAILSERVER are being routed through OLDMAILSERVER as it's still the master and the server being pointed to by our DMZ frontend.

3.) Messages from mailboxes still on OLDMAILSERVER are still routing through OLDMAILSERVER as well.

4.) Any messages to the new mailboxes are getting stuck in the queue on OLDMAILSERVER, coming back with an error that NEWMAILSERVER is failing to respond.

Seems weird because I can send from NEWMAILSERVER to OLDMAILSERVER, just not vice-versa. So I know they are talking to each other, but all these messages are piling up in the queue.

Any suggestions?
 
Is the MTA running on both?

When you send a message from oldmailserver to newmailserver, does it sit in a queue for a while? If so, which queue?
