It's going to be different for each environment so it's not a hard rule. If you have other protections setup around SA like RBLs to reject, honeypot MXes that tempfail, etc., then SA only has to scan a small percentage of your messages. This equates to a very small percentage of silent discards for obvious spam which keeps you from being part of the backscatter problem. A large percentage of mail that makes it to my SA is clean mail. I do have the occasional false positive but we quarantine everything and can release it as needed. I have never had customer ask to release a message that scored 2x above our block threshold or had a virus so these are definitely safe to silent discard as long as local laws allow it. Dave
