I would like to ask you, how can I *allow **only **legitimate* email addresses (existing users) for bayes learning?Table bayes_token grow up to 0,5GB right now, because there are thounsands of unknown email addresses like: a...@hotmail.com ablewi...@hotmail.com abl...@hotmail.com
don't use auto-learning or at least adjust the scores which are taken for autolearning - SpamAssassin can't know if a address exists while you could use http://www.postfix.org/ADDRESS_VERIFICATION_README.html on the MTA level
*but* be careful with sender verification, you need to place a lot of DNSWL in front to not become blacklisted for your own
i guess your main problem is that way too much mail makes it to SA at all instead block it by RBL scoring and other MTA restrictions long before - see below an example, all the stuff before the bayes stats never touched SpamAssassin
