per-user spam folders

Hi!  I've got a working qmail-scanner + qmail + spamassassin + clamav setup.

What I'm trying to add to this, however, is per-user spam folders.  That 
is, spam that was sent to "[email protected]"  -- I want this to be put 
into HIS maildir, into a spam folder.

Is this possible with qmail-scanner?  how would I go about doing this?

Sorry for such a basic question!  My google-fu failed me on this one, 
and I didn't see anything in my skimming of the archives of the list 
that pertained to this problem.  Thanks for any help you can lend me :)
