Amy, I'm not sure I understand your question. MX records don't really
pertain to a FE/BE setup, they pertain to the delivery of SMTP mail from an
outside mail system. If your FE server cannot access your "master" BE
server, there could be network configuration issues involved. Can the FE
server correctly resolve the DNS name of the BE server in question? Is there
a firewall in between the two servers, and if so, is port 80 open?

Have you read this msexchange.org article:

Subject: [exchangelist] Front End/Back End

http://www.MSExchange.org/

I have a front end server that can access mailboxes (OWA) on the Back end
cluster, but not the Back end single Master server. (500 internal server
error)
All 2000 server and exchange. 

We had to create a new domain because the internal and external had the same
name (split). 
The master has an internal and external NIC. 

We have an MX record that is pointing to a host record that is using the IP
address of the external NIC of the master back end server. I'm thinking this
might be the problem. The internal NIC is not configured with a default
gateway. Does anyone agree that removing the external NIC and configuring
the default gateway on the internal NIC should fix the problem?

Thanks
Amy
