I don't think I'd go w/just one MS gateway.  Eggs, basket, that sort of thing.  It's really handy being able to update/upgrade a gateway server and the users never notice the difference.  They're all connecting to an internal Exchange server.  Being able to bring my MailScanner boxes up or down w/o them noticing is a real treat.

I service several domains and just use the mailertable to route to the appropriate inside host. I don't use the virtual table at all.  At the gateway level I don't care about users so much as domains.  I do use smf-sav to verify recipients at the gateway but then just send the messages to the appropriate server.  Works well for us...

I'm running sendmail FWIW...
