I've been doing some reading up on Exim. Exim is able to do sender verification also. But it's also able to verify against a database. So, I can build a (postgres?) database for my white/black lists and I can accept/reject these addresses during the smtp transaction. Now, I understand that tmda can be configured to store it's white/black lists in a (postgres) database.

Wow! Care to share your freemail list? I could be a bit more liberal in my policy for senders who are NOT on that list..... And I could be a real Nazi to those who are.
