It is true that Bayes works best if you can customize it on a per-user
basis bit that is NOT necessary. It DOES work even when left to run
on a site-wide basis with just the training from auto-learn.
As an administrator running SA with Bayes site-wide on a system that
processes tens of thousands of messages a day for thousands of users
with no per-user configs, I know of what I speak.
If you cannot do any hand-correcting (re-feed it ham/spam to correct
mistakes) you might want to adjust the scores so that just a
Bayes score cannot be responsible for the total determination of
'spam'. IE with the default spam threshold ==5 and default Bayes 100%
score ==5.4, a mistake in Bayes learning could be soely responsible
for a message being marked as 'spam'.
So crank up your spam threshold to 6 or so to require some other rules
to corroborate the Bayes assessment.
Bayes does use up a bit of memory and CPU, but it's small potatoes
compaired to some of the add-in rules that have been discussed on
this list (Hi Chris ;).
So please give me one good reason why you say Bayes:
"isn't even an available option to some of us"
