Second Exchange Server - Public Folder Problems

Hi all,

We just added a second MS Exchange 2003 server.  The installation went through without any problems.  The mailbox stores are working fine...any messages sent or received by a user is delivered.  The problem I am having is with any messages sent into the Exchange environment destined for a public folder.

On the old server, I see two queues building up:
newinternalserver.domain.com (hundreds)
Messages Queued for deferred delivery. (about 25)

In the internalserver.domain.com queue, amongst the messages are hundreds that look ike:
from OLDSERVER-IS@DOMAIN.com, state is retry, subject is either hierachy, folder content, or status request.  Any test messages I try to send to public folders end up here first and then cycle between this queue and the Messages Queued for deferred delivery queue.

The new exchange server's queues are empty.

I can telnet port 25 from the old server to the new one and visa versa.

The old server does have an entry in the event viewer that says "DCOM was unable to communicate with the computer mail.domain.com (this is my first MX record) using any of the configured protocols."

If I track a message from an outside source to a public folder, this is what is returned:
SMTP: Message Submitted to Advanced Queueing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Message Queued for Local Delivery
SMTP: Message Queued Locally to emailaddress@domain.com

SMTP: Message Submitted to Advanced Queueing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Message Queued for Remote Delivery
SMTP: Started Outband Transfer of Message
Message transferred to mail.domain.com (my first mx record) through SMTP

and then looks like it goes through this loop over and over.

Please help!  Thanks in advance!

So in a nutshell...messages that are trying to be delivered to the public folders are being caught up in a queue, they try to be delivered locally, but then try to deliver to our MX record, which creates a loop.

Do you have a smart host set on the SMTP virtual server?
If you do then it must be removed.

When you say your first MX record, is that not pointing at your Exchange server? Message tracking just shows what the remote server announced itself as, it doesn't mean anything more.
