Just a FYI really... I have written a plugin that uses DB_File to store the IP address of incoming connections. If it's the first connection from that IP address it returns DENYSOFT. Otherwise it lets it continue.
I didn't invent this idea - lots of people have suggested it before now. It's just dead easy to implement in qpsmtpd... The theory is that spammers don't queue - they fire and forget. The only system that would queue is an open relay, and those seem to be few and far between these days. So far, no spam today, and lots of DENYSOFT's returned. All my other mail seems to have come through just fine. I can't give the code away as this is work-related. But I'm sure some other bright spark can do it. It's about 10 lines of code. -- <!-- Matt --> <:->get a SMart net</:-> Spam trap - do not mail: [EMAIL PROTECTED]
