Thanks for your reply.
Adsl users sending spam e-mails using their adsl connections. I can filter IP addresses from firewall btw, But adsl users have dynamic ip addresses. Dropping a connection will drop all. I want to block whole adsl ip range (/24 or more), *unless they are smtp authenticated* So that my smtp authenticated users can send e-mail, but other will not be able to send e-mail to my users. It's something like rbl black listing.
