You can do this easily with procmail.

Into the file bounce.message, put some text describng why you are
bouncing this mail.  Then, set up the user's .forward or .qmail to 
use procmail.  Then, add this rule to the .procmailrc :

       :0
       * ^From drevil@spam.com
       | (formail -r ; cat bounce.message) | $SENDMAIL -oi -t
