In preparation for the World IPv6 Launch, inbound (SMTP) email to the
comcast.net domain was IPv6-enabled today, June 5, 2012, at 9:34 UTC.
Roughly one minute later, at 9:35:30 UTC we received our first
inbound email over IPv6 from 2001:4ba0:fff4:1c::2. That first bit of mail
was spam, and was caught by our Cloudmark messaging anti-abuse platform
(the sender attempted a range of standard spam tactics in subsequent
connections).
In the past several hours we have of course seen other messages from a
range of hosts, many of which were legitimate email so it wasn't just
spam! ;-)
Since the Internet is of course more than just the web, we encourage
others to start making non-HTTP services available via IPv6 as well.
I always wondered why (ISPs) never started with rolling out IPv6 email
servers first, the fallback from 6 to 4 is transparent and invisible to
the end user at a delay of a maximum of 30 seconds.
I enabled v6 for my email before my website since the impact if it
didn't work on the 1st try was almost nil.
Still waiting for the 1st Country to top Romania' 6% deployment. I'm
sure we can do better then 0.21.
IMHO Asking users if they want IPv6 is the wrong way round, you enable
IPv6 and then allow for opt-out in the service portal.
That's basically what the Romanian ISP did. They have not gone bankrupt
either, so maybe it's not all as bad as we think.
