Hi Doug,

My point is that all the hooha about "We can't do mail over IPv6
because we can't do IP address reputation" seems to be nonsense. There
are plenty of ways to do spam filtering that don't involve keeping a
log of every single IP address that sends spam.
People are used to blocking spam by IPv4 address. That makes it
difficult to explain that it is no longer the better way for IPv4
connections, and nowadays for IPv6 connections.
Sorry I wasn't clear, but my post was already long enough. I understand
that blocking spam by IPv4 address hasn't been an effective solution by
itself for many years now, and I understand that the vendors are crying
foul because IPv6 makes their snake oil sales harder.
My purpose was to offer some actual concrete numbers from a mail server
that's hit relatively hard with spam, to demonstrate that the entire
argument of "We can't filter spam on IPv6" is specious. :)
