Yes, but the number we use to train on isn't.

AFAIK, this experiment is still ongoing. Particularly, the Outlook default
config file still has:
# This will probably go away if testing confirms it's a Good Thing.
I guess it can safely be stated that testing has not proved it a bad thing,
but that isn't what the comment asks <wink>

I am approaching that. My problem is that I delete items from my Inbox, but
never delete them from the Spam folder. This is mainly for training
purposes, but I guess it could come in handy when I need to make money fast
<wink>. However, the end result is that my spam:ham ratio is slowly
Human perception gets in the way though. It was not that many months ago
that I considered 20 spam a day bearable (and from what I understand, a .au
address means only 20 makes me lucky!). Now I find that for any "unsure"
items that are found, I begin to wonder if SpamBayes is no longer doing its
job. I believe the truth simpl is that SpamBayes has lowered my threshold
to the point where whenever I see *any* spam I recoil.
