When I tried it I spent more time tweaking lists than reading mail. When a previous employer of mine tried static lists it turned into a full time job for one of our sysadmins. In my experience, grey listing at the SMTP server offers the best bang for the buck. It drops on the order of 95% of incoming spam before it can get into the mail server with no false positives -- it won't drop legitimate mail. Grey listing requires no maintenance and it is very light on system resources. -- Rich P.
