set verify_sender to verify ur users b4 accepting the email (as long as the
users are local or u have setup up some other sort of verify method)
and prob verify_recipient to reject unknown users b4 it enters ur mail
server
The filter runs over the message after it has been accepted by exim, which
is why it is freezing.
