What are you using for a mail server? I'm using postfix for a mail 
server at an ISP and at one stage started writting a postfix policy 
server in erlang with mnesia support to allow grey listing to work 
correctly across multiple servers. It was shelved early on. Might be 
time to drag it out and take another look.
