We use action_bounce to stop mail from coming in for 5,000+ accounts and all of our customers love it. You will always have 1 person who doesn't want their mail scanned no matter what. It is doable in an ISP environment but it takes some effort to get things working smoothly. Be familiar with creating nice rules, set your blocking threshold high like 6.5+ and keep a close eye on things, but it's nice when you sort all the issues out! If you have customers overseas be sure to watch out for RTBL's, we've been bit by those in the past. We've been using MIMEDefang with SA and ClamD for over a year and I would never recommend anything else. Might I also say MIMEDefang is not for the weak hearted, it can scare you if you are not prepared ;)
