You can train the Bayes filter by using the sa-learn program. See man
1 sa-learn for more specific about how to use it. Basically, you take
a minimum of 200 messages known to be spam (I use mbox format) and run
it through such as:
# sa-learn --showdots --mbox --spam /path/to/file
You also need a minimum of 200 ham (non-spam) messages, using the
following command (again, mbox format):
# sa-learn --showdots --mbox --ham /path/to/ham/file
SpamAssassin should learn on it's own and will begin invoking the Bayes
filters once it's had the minimum of 200 messages of each spam/ham. If
you want more accurate results, feed it more mail. I save spam I get
and try to run a bunch of it through every few months, and I do the
same with ham.
