been setting up postfix email servers so I know how complex these
things can be...
If you have separate real ip addresses for the 2 servers then sounds
like you have not set the dns entry for the 2 emails servers correctly
in the m0n0 box.
"dig mx mailserver1.yourdomain.com ;  dig mx
mailserver2.yourdomain.com" from the dmz and then from outside your
network and you should get the information you need to debug this.
of course it could be an smtp/mta issue :-)
