Fine grained mail filtering with IPv6 Email

One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam.
