Does postfix offer anti-spam support at the connect level? For example, MimeDefang can drop an incomming spam email during the connection thanks to sendmail milter support?
Postfix has header checks and RBL checking ability at the connect level, before it accepts an incoming mail. You can also filter on lots of parameters based on the sender, receiver, valid address and domain format, valid MX, etc. Postfix rocks the free world.
