OK - But how do I get lists.mlsnet.com to relay mail to the mlsnet.com mail server. Subcribers from the mlsnet.com domain are not receiving any news letters sent out from the lists.mlsnet.com server. I am getting a connection timed out when it tries to contact the external MX records.
I have added an entry in my hosts file that looks like this:
10.10.10.1 mlsnet.com
which is the internal ip of the mlsnet.com mail server.
Your help is appreciated..

In DNS you would have something like: lists.mlsnet.com. A 216.216.23.43 MX 10 lists.mlsnet.com MX 100 mail.mlsnet.com
In this scenario all mail to user@lists.mlsnet.com will be delivered to lists.mlsnet.com. If that server does not respond then the mail will be queued up on your main mail server: mail.mlsnet.com
This assumes that you can setup the other mail server to act as a secondary. If not, then just leave it off.
And "yes" virginia, you *do* need an MX record. If you don't have an MX record then any mail to lists.mlsnet.com will be dumped out to your main mail server (using your domains MX record). You could setup some internal routes on that server to shuffle mail over to lists.mlsnet.com, but that would be counter to your stated intention of moving the load away from the main mail server.

If there's an 'A' record for lists.mlsnet.com, and this is the host they want mail for lists.mlsnet.com to be delivered to, there is no need for an MX record. It's good practice to have one, but it's absolutely not required.
And if you're trying to say that (if an MX record for lists.mlsnet.com is absent) mail for lists.mlsnet.com will be delivered to the machine that's the MX record for mlsnet.com itself, you are completely, 100% wrong.
