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 18.104.22.168
doors.huapi.net.ar has address 22.214.171.124
doors.huapi.net.ar has IPv6 address 2002:be88:b1de::1
puck:~$ host warner.fm
warner.fm has address 126.96.36.199
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 188.8.131.52
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..
