Ahh. That makes sense now. I think what you might be better off doing is
to turn off the chkuser patch as your not really using it in this
situation. Then you could set your .qmail-default to send anything to
either delete or to a users mailbox to be double checked. From memory
simscan allows emails which have a virus to be sent to a quaratine (and
maybe deleted too, i cant quite remember) so it should also be usable. 

There is a heap of options in the chkuser patch too which you may be
able to play with to change its behaviour to suit what you want.

cheers
