I think you have misunderstood what Denis meant. It sounds to me like  
he bounces what looks like Spam back to his students. I would guess  
(Hope?) he is using smtpauth or some other check that prevents the  
students from relaying with a faked from address, so he knows who  
they are. By bouncing the mail back to them, it stops their mail  
being silently dropped or otherwise undelivered (Or worse still  
putting the University on a RBL). I don't believe that Denis is  
suggesting he bounces Spam to any one other than the local users. You  
don't do you Denis?? :-)
