[Mimedefang] Dropping the smtp connection from filter_recipient

[Wayne]

Is there anyway I can drop the tcp connection from filter_recipient. I have
a list of blackhole usernames the I check against in filter_recipient. If a
message is sent the one of these addresses I add the ip address to my
access.db file in send mail the only trouble is if the smtp connection is
not dropped the spammer can keep trying addresses with out being blocked.
