So it's yet another chicken-and-egg problem to add to the pile
for IPv6. Mail ops don't care because IPv6 isn't here, net ops
delay IPv6 because mail isn't ready for it?

This seems like to sort of problem that Mailops or MAAWG should
be hammering out. There's a great opportunity to get some good
BCP documents out there on "Here's how to do email in IPv6"
before deployment goes past the point of no return.

Spamhaus has had a fair amount of success with getting ISPs to
participate in things like the PBL. Why not establish something
similar for allocation sizes in IPv6?
