your users keep ham-messages in the Spam folder? The antispam plugin
triggers as soon as a message is copied from a SPAM folder into
another folder, that does neither match spam nor trash pattern.
However, the problem is what spam folders to use, IMHO. If you use a
folder, that is used by MUAs to automatically move spam into, you
might learn false positives. Some systems cannot "unlearn" a message
100%, so you poison the database.
If you use another folder, your users won't move messages from the
MUA's junk folder there, hence, you miss spam.
