we have spammers who are sending mails a.b@comp.com.
then he sending to all not existing users like a.c@comp.com, a.d@comp.com
and so on....
now we restricted the BM-Mail-Proxy to allow only exactly all user-
accounts. But not more.

But when im looking in the incoming dir, there are still coming still spam-
mails comming in. But i don't see then afterward in Groupwise.

How can i avoid this mail coming in to the incoming dir

with regards
