Funny. I thought we were discussing ``IPv6 SMTP requirements'': things
that every MTA is going to have to do as part of the IPv6 transition.
Apparently you have a different goal. You want to work with existing
MTAs. You want to work with MTAs that don't know anything about IPv6.
In that case, writing a spec is rather idiotic. You have to use the
_existing_ protocols. You have to work with what the MTAs do _now_. In
other words, you have to support IPv4.
Of course, as long as that's the situation, IPv6 is a failure. IPv6
addresses will be functionally identical to 10.* addresses. Users with
these second-class addresses aren't actually on the Internet; they need
application-level relays to talk to the Internet. Everyone will continue
to compete for real Internet addresses: connected IPv4 addresses.
