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?
Well, maybe? I don't currently have a system using per-user Bayes and
it's been a bit since I set one up so hopefully someone who has a
working rig will speak up...
Note that SA will try to create an empty DB if none exists. I'm not sure
that I can think up a circumstance (other than a disappearing user)
where fallback to global Bayes would happen. SA will not fall back to a
global Bayes DB just because an otherwise perfectly good per-user DB
isn't properly seeded.

Hi,
Trying to implement user specific bayes. My current setup is setup as
follows in regards to global bayes. I'm also using amavis:
bayes_path /opt/sa-bayes/bayes
bayes_file_mode 0777
Don't do that anywhere. It's not safe.
use_bayes 1
use_bayes_rules 1
bayes_auto_learn 0
bayes_auto_learn_threshold_spam 15
bayes_auto_learn_threshold_nonspam -5
[...]
and it did seem to create bayes_toks and bayes_seen files under the
/opt/sa-bayes-users/b...@domain.tld<mailto:/opt/sa-bayes-users/bob@doma
in.tld>
directory as expected.
So, it is working.
Is this all that's required to get this working?
Yes
What happens to the global bayes file in local.cf? Is that no longer
used?
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.
