As for v6 how popular do you see it getting for mail?
Are you implying that when the internet otherwise moves on to IPv6, we'll still inexplicably use IPv4 for mail?
IMHO mail is one of the easiest "first things" to turn on for IPv6. Nobody is going to really notice a 1s delay if they connect() and you're not listening on IPv6 but are on IPv4. There are concerns from the spam/blacklist communities that IPv6 will make it too hard to roll-up spam information, so many enterprises will likely stick to IPv4 along the long-tail of deployment as it will nearly always work. I also see lots of people with 2002: address in my mail-log relying on 6to4 gateways, e.g.: puck:~$ host doors.huapi.net.ar doors.huapi.net.ar has address 190.136.177.222 doors.huapi.net.ar has address 168.83.68.202 doors.huapi.net.ar has IPv6 address 2002:be88:b1de::1 puck:~$ host warner.fm warner.fm has address 66.59.109.136 warner.fm has IPv6 address 2002:423b:6d88::1 warner.fm mail is handled by 10 argo.pyxos.net. puck:~$ host x25.se. x25.se has address 83.227.190.248 x25.se has IPv6 address 2002:53e3:bef8::1 x25.se mail is handled by 1 x25.se. I suspect folks will run these sorts of gateways for some time.. - Jared

You can certainly turn it on, and it will work at the current toy scale, but nobody has a clue how we're going to scale IPv4 spam management up for large scale IPv6. Anything that's obvious won't work.

It isn't a complete solution by itself, but SPF hardly breaks a sweat with IPv6 and helps with maintaining domain-name based blacklists. -- Daniel Taylor VP Operations Vocal Laboratories, Inc dtaylor@vocalabs.com 612-235-5711

I've been receiving spam over v6 for about 12 years at this point.
