Good Afternoon Sir Falko, I have some questions regarding the local.cf on your spamassassin amavis configuration. There are lines there: #bayes use_bayes 1 use_bayes_rules 1 bayes_auto_learn 1 what do these lines do? i mean what is the bayes_auto_learn trying to learn? the spam messages it receives or something? I would like to know the functions. Thank you so much. Joel
