I'm surprised that greylisting is only blocking 35% of your spam. I have found it to be more like 98 to 99% effective by itself. We went from 3000 to 6000 spam messages a day down to 5 to 10. This is using milter-greylist with sendmail and a very short delay timeout of a few minutes. Spamassassin picks up the remainder very easily. -- Scot L.
