Sorry.  Yes, when a message is "untrained" the database forgets about it
completely (message count is decremented, all token counts adjusted down).

    Dave> Why not?

I don't use the imap filter.  I presume it has its own way of managing your
hams and spams.

In theory I suppose it can.  The ham and spam mailboxes are opened using
mboxutils.getmbox() which presumes to be fairly format agnostic but I don't
know if it will work with IMAP folders.  I see no mention of IMAP at all in
mboxutils.py.  I suppose this might be a case of "patches cheerfully
accepted". :-)
