No matter what 2821bis will say, when IPv6 enters the picture
they need to talk. The mail guy in an IPvX network will want
mail from non-IPvX networks.
Frank, the school of thought for a successful migration to IP6 will
largely depend, at least initially, on the availability of dual stacks
which will help in the smooth migration. From that standpoint and as
well from having no real market pressures, I have felt no urgent need
for radical changes or mad rush to implement direct support for IP6. It
might be "simple" to discuss this from an admin standpoint, but from a
engineering standpoint, systems who are going to mix will need to change
their DNS clients software implementations radically. Those are the facts.
But I think overall, there are two discussions going on here.
1) A vs AAAA fall backs, and
2) Mandating MX for Email Security Policies
and as you know, the latter is part of the wishes of the ASP group.
I have long stop trying to figure things out here with the different
motives people have. People speak from both sides but the SSP/ASP group
was told long ago they were going to have a problem trying to mandate a
MX record tied to EMAIL security. They ignored the warnings from SMTP
developers in the SSP/ASP discussions and/or move the discussions to non
WG rooms and now they are attempting to throw in their day late (and
dollar short) last minutes wishes on 2821BIS in hope it will make their
ASP proposal more viable.
