You're right I've asked the admins at the hosting location to add some 
options to do this and they did this ...
they have 2 options added to the setup ...one that black holes the stuff 
and an other that just rejects it if it is
undeliverable... I've chosen option 1 for the non mx record hosts and 2 
for the mx listed host... but now you
mentioned it i'll just change them all just to reject the mail if the 
user is unknown.

Thanks,

Michael.
