No need to bother with bayes_seen, just purge it every once in a while when it grows large. > > Some people include atime information for that purpose. > > Yes, thanks..

The main purpose of bayes_seen is to prevent a stream of same-contents messages arriving in a short succession from polluting a bayes database. It is unlikely that a same contents message arrives more than once during a long interval, and even if it does, there's not much harm done even if re-learnt. I believe the bayes_seen had its purpose when mail viruses were frequent and spam messages were arriving in non-personalized batches. These times have long since gone. Mark
