Hi, thanks for the quick reply. So when amavis calls on SA for an incoming message, it will pass the recipient (e-mail address) in the %u variable and then SA will take that variable and look in the /opt/sa-bayes-users/%u directory for the existence of bayes database and if it finds one, it will use it provided it's properly seeded. If not, it will fall back to the global bayes. Is that correct?

I believe that it would be used if for some reason SA couldn't figure out which user to pick for a scan at runtime. Maybe if spamd was launched as a user that was later deleted? But generally, working per-user Bayes setup makes the global file pointless and unused. > > How do the following settings from the local.cf figure in the user > specific bayes files? > > use_bayes 1 > use_bayes_rules 1 > bayes_auto_learn 0 > bayes_auto_learn_threshold_spam 15 > bayes_auto_learn_threshold_nonspam -5 The local.cf file is loaded before user_prefs, which is the last config file loaded, so anything that can be changed in user_prefs (i.e. all of those, I believe) which is set in user_prefs will 'stick' Note that in this case you're choosing to disable auto-learn, so the threshold values are never used. > Do the user specific bayes have the same requirements to train them > with at least 200 messages? Yes. Each Bayes DB must be seeded before it can be used. You should also plan a way to regularly feed known spam and ham to those databases, since you aren't auto-learning. > before they start working? Before SA will determine a Bayes score on incoming messages, yes. -- Bill Cole b...@scconsult.com or billc...@apache.org (AKA @grumpybozo and many *@billmail.scconsult.com addresses) Not Currently Available For Hire
