None forthcoming, so I'm putting this down to a freak bayes database corruption. sa-learn --dump magic now shows 161 spam and 69310 ham learnt, and I'm letting it sort itself out. In about 3 months I guess it will be back to normal :-). Spamassassin works fairly well without bayes, so I don't mind too much, but I would feel happier if I thought that what happened was understandable. Chris
