MS Exchange 2000 / 2003 Open Relay Filter

A freeware Open Relay Filter (DNS RBL, etc) for Exchange 2000 and 2003. Text description below from Martijn's site. It's freeware, I've not tested yet in production but it looks interesting.

What is ORFilter?

ORFIlter (Open Relay Filter) started as an Open Relay Filter based on RBL's (Real Time Blacklists) for Microsoft Exchange Server. As this is still the main functionality, I've added more features over time, like keyword filtering, SURBL, and custom black and white lists. ORFilter operates on your mail server, not on your mail client. When detecting / suspecting a spam message, it's depending on the score, either deleted, redirected or let through with an altered subject.
