Hello,

Yes, you need to configure SA to use bayes. In our case SA is installed
into /etc/mail/spamassassin. In there I have a 'local.cf' which
contains:

use_bayes 1
bayes_auto_learn 1
bayes_auto_learn_threshold_spam 7.0
bayes_auto_learn_threshold_nonspam 0.5
bayes_path /etc/mail/spamassassin/bayes
bayes_file_mode 0777
bayes_use_hapaxes 1
bayes_use_chi2_combining 1
bayes_auto_expire 1

The bayes_path states where to write the files. However, I'm not sure
that you can get it to do a per-domain bayes db - an interesting idea
mind you! You may well want to modify the 'auto_learn_threshold' options
accordingly. Bayes only starts to be used once a number of messages have
been scanned as spam/ham - 200 by default I think.
