Bayes only if -u specified?
Hi all,
Quick question. Is it possible to set up spamassassin to use Bayes
only if the -u option is passed via spamc? I'm using simscan to call
spamassassin and if the user is not specified, it falls back to the
nobody account. The bayesian database fills up with tons of tokens
that I believe are hurting, rather than helping, the identification of
spam.
Thanks,

Duh.. Should have thought of this.. Ok, trying this out now..

Two options, since you're using spamc/spamd.
1) Put user configs into SQL and for user nobody set use_bayes 0, you
might get similar results if you give user nobody an actual home
directory and a user_prefs file, but I've never tried that.
2) There is a plugin hook that you can use that allows you to authorize
bayes for specific users. It would be pretty trivial to write an
everyone except user nobody plugin to do what you want. Here is a
sample plugin you could build off of:

Yeah, I'm turning on autozap today :P

Some options:
(1) turn off autolearn.
(2) if you suspect auto-mistraining then adjust your auto-training
thresholds.
(3) zap nobody's bayes database nightly (hourly?) in cron.
