Very usefull filter, thanks Davide! Just a few words on a possible improvement. It would be nice to have something like the embargo policy implemented in DCC greylist.
Maybe I'm wrong, but it would just need the md5 checksum algorithm of the message body, a few new columns in the dbm and... some code... "DCC greylisting normally requires not only that a triple of sender, recipient and SMTP client IP address be familiar, but also that a triple does not become familiar until the same message has been presented and temporarily embargoed or rejected. This significant difference from other implementations prevents a spammer from retransmitting a different message (e.g. with different random words) to get past greylist filtering." from: http://www.rhyolite.com/anti-spam/dcc/greylist.html Dario - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
