Sounds fair enough to me.
The other mode would be to set up mail.ipv6.yahoo.com and have
customers use that for whatever protocol they send/receive mail with,
and not point an MX at an AAAA for the time being. However, that
means that you can't simply turn it off if it becomes a problem
(although, you could switch the AAAA out for an A), and when you end
up being able to do a "proper" IPv6 deployment you end up with
customers still caring about this legacy DNS entry. That, in short,
