Check out this very old presentation about the Mail Abuse Prevention System (MAPS) , from October, 2000.
I had already left MAPS at that point, but apparently, my personal brand was strong enough to leave my name in the presentation, as it indicates that RSS was created by me.
Also, I designed that presentation template, as well as the MAPS logo and logotype of the time. Oh, how horribly dated it all seems today.
MAPS created the first Realtime Blackhole List (RBL), the very first DNSBL, way back in 1997. It's hard to believe that anti-spam blacklists are over ten years old!
One of MAPS other blacklists, RSS, was a re-branded version of my original Radparker Relay Spam Stopper (RRSS) blacklist, which I first shared with the world back in May, 1999.
