First of all, hello and welcome.
About me and when I get spare time , I am an active anti spam activist administrating on some of the worlds largest blacklists although it did get me in a bit of hot water a few years ago when I become the first person in the world to be sued by a spammer.
Two questions: how did that work out? (and a subsidiary question - Was it Spamhaus or SPEWS you were involved with at the time?)
And can you comment on the future of SPF (Sender Policy Framework) in regards to spam reduction?
