I don't use the Anti-Spam plugin; I just fire off a BASH script every

Thanks, Bill!
Sure, please do share the script, if it's not too much trouble.
For my specific use-case, I've been maintaining a "corpus" of known
ham/spam messages, and enjoy being able to hand
classify/re-classify/ignore if necessary.
But I do see the appeal of training with a single script that iterates
through each user's mailbox.
Heretofore, my thinking has been that combining all "submitted" spam,
which is piped into the training mailbox automatically, whenever a user
drags from Inbox -> Spam (or vice versa), I have a much broader sample
of the the ham and spam out there.
And yes, a "shared" corpus among all users does seem to "dilute"
specific individuals' would-be training preferences a bit, but the
trade-off seems worthwhile.
Interesting quandary... I would love to see the script! No problem if
it's a bit "rough around the edges"; the overall concept and approach
are what's important to me.
