.forward caveat

Hi!

        This has probably been done to death on the list, but I'll risk 
bringing it 
up again, because it's not in any of the man pages. 
        I have a simple recipe that bounces mail back to a particularly 
annoying guy 
which looks like this:
        
        :0
        * ^From:(_dot_)*bum(_at_)some(_dot_)place
        {
                EXITCODE=67 HOST
        }
        
        The idea is that he gets information which states that I don't exist 
(I'm 
getting existential...sorry :). The problem is that he also gets my .forward 
file in 
the bounced e-mail so he knows that I do indeed exist. Is there anything I can 
do 
about this? I could probably just /dev/null his posts, but I want him to stop 
mailing me altogether and that's not the way.
        
        Thanks for any help!
