John, First, let me mention that I'm grateful that you are working on this! We certainly need your help! To be extra clear, the kind of sender's list I was talking about wouldn't be the same as a yellowlist because it would ALL types of IPs (black, white, yellow). Except everyone... including spammers... would have to jump through some hoops to get a single IP that list. But this /then/ VASTLY lowers the number of possible IPs that could be subsequently be whitelisted, blacklisted, or yellowlisted. And even though you mentioned that FCrDNS wouldn't work as a spam filtering defense... things like FCrDNS could still be of used as a criteria for entry into this "master IPv6 sender's list" (as a means to keep the volume further under control.) -- Rob McEwen http://dnsbl.invaluement.com/ r...@invaluement.com +1 (478) 475-9032
