Depending on the volume, you can do something similar to what we did. Take a Linux box, install 2 NICs, load on your favorite MTA (we used Exim). We have split DNS, so only what we want the public to see goes in the outside DNS, and the full version is on the inside. Advertise your new 'outside' mail server as your 'real' one, and when it gets to that one, it should be able to hand it off to the 'real' one, inside your perimeter, with the proper config.
