Currently I have this in the mailertable:
domain(1).com                     smtp:smtp2.differentdomain.com
domain(2).com                     smtp:smtp2.differentdomain.com
Domain(n).com                     smtp:smtp2.differentdomain.com

I think that I'm going to have to test this out and see what happens.
