Thanks to everyone...
who posted in response to my Postfix. We'd actually figured it out way late at night and I was too tired to post a follow up.
Yes, we used the virtual aliases. I'd followed the instructions on the Postfix site about setting up a firewall which had me disable local deliveries and then immediately followed it up with "But you'll need to deliver some locally" which confused the hell out of me. Even though I thought that I'd reset everything back later for another try, I'd missed one item.
See what happens when you stare at something too long?
Thanks anyway for the pointers. Y'all rock!
