I seem to recall a key feature was, once they successfully connected to a IMAP (or was it POP) server, the IP address they connected from at the time would be temporarily allowed to relay through the SMTP server. There are mailing list archives from that website; and I see one link: http://www.davideous.com/smtp-poplock/ David Harris has a similar system to only allow hosts who have authenticated via the POP3 server to relay mail using qmail. This does not require patching the POP or SMTP servers, but is implemented by two programs which cleanly interface into the system, and can work with most any POP or IMAP server. -- Brian 'you Bastard' Reichert reichert@numachi.com 37 Crystal Ave. #303 Daytime number: (781) 899-7484 x704 Derry NH 03038-1713 USA Intel architecture: the left-hand path To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
