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
