SMTP needs to die. The most realistic candidate to replace it IMHO is
federated XMPP with appropriate semantics for store+forward, mailing
lists and forwarding (easier to handle, as the s2s link can use callback
to authenticate the forwarder).
Scalability is a concern, but with DomainKeys imparting a per-message
crypto check (and a more-than-somewhat complex one, at that) I can
imagine the costs reaching parity or the differences disappearing into
the noise soon.
There's the flag-day problem to solve, but frankly the alternatives of
forever poorly-functioning DKIM/SPF alternatives or worse,
balkanisation, make this attractive to me.
It's also a much better protocol for some of the ad-hoc uses e.g. file
transfer, cron job output collation, out-of-office/presence and rich
formatting, than SMTP+MIME. It even has VoIP support (though how that
will cooperate or compete with SIP remains to be seen).
We are of course talking about a decade or more before even a slight
amount of progress is made.
