I know that. What I *WANT* to know is who (if anyone) is attempting to bounce spam off my SMTP proxy, so I can go complain to their ISP, the same way that I do if someone tries to telnet into my network.
Please notice that my original message did not ask for changes in the SMTP proxy functionality, only that it be given the ability to send alarms when it rejects an SMTP connection or session.

Everything that it accepts after applying its own anti-spam rules (reverse DNS check, MX check, MAPS check, etc.) gets passed to the internal mail server, regardless of the ulitmate destination address. If you're using the "Accept only these domains" feature or the MX check feature, then you're preventing relaying right there. Your internal mail server may (and probably should) even go beyond that. -- Alex Howansky Wankwood Associates http://www.wankwood.com/ ---------------------------------------------- To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe gb-users your_email_address in the body of the message
