There is a gotcha in doing that, Glenn. One person's spam is another
person's ham. It is better if each user has his or her own Bayes rules.
For that I built a pair of IMAP mailboxes into which I can dump the
spam and ham samples for each user. If doing this for other than me
or Loren I'd dump them once they had been processed, sight unseen by
human eyes. Neither Loren nor I seem to be as interested in each other's
ham and spam samples as we are in eliminating spam. So I save both for
retraining Bayes if something tubes the Bayes system.
Since going to the trouble if creating IMAP mailboxes, which are a very
general solution if spam is moved into them for disposal, I have discovered
that the OE MUAs we use can simply export the spam as individual files by
drag and drop. That could be used with a SAMBA exported directory on the
mail server for generic training with one "spam" user account or it could
be done per user with per user spam accounts. While I know I can do this
I prefer the IMAP trick. It works and is somewhat easier.
Note that I do NOT use forwarding for exactly the consideration you cite.
I move (or copy) spam into the spam folder and let a cron job train the
Bayes for each user at least once a day.
