[Mimedefang] greylisting does it still work?

[Wayne]

Hello All,

I have started to receive a bunch of spam in the last couple of weeks and 
looking at the messages and headers I can't seem to find a way to get them 
blocked. I was wondering if greylisting is still affective? Near as I can 
tell this seems to be my best option. The messages have become so short and 
plain that I am not getting the points from spamassasin to block them.
