Using spamc/spamd combination rather than spamassassin will dramatically
decrease scanning time. Also, when training Bayes filters this way, you
probably want the --no-rebuild option and periodically rebuild the
Bayesian database.

Depends -- identified SPAM which is below the autolearn threshold should
be learned manually to optimize results. Already learned messages are
recognized, thus learning again does not do any harm.

Yep, learning HAM as well is important.
