We can't presume everyone has a full time internet connection.
100% agree. Store and forward is still required in some part of the
world. I developed XATRN (http://xatrn.panozzo.it), and there are still
very some (few, very few) users that use it with intermittent Internet
connection. Yes, I think that the future will be for always-on
connections, but there is no full world coverage of such kind of
Internet access.
They authenticate over sasl using some fancy
federated authentication protocol (project moonshot) before being allowed
to post to my inbox.
Personally I'd be tempted to mandate use of X.509 (SSL) client certs and
TLS.
Maybe X509 can be one of the weapons against spam. But today spam comes
from a "stolen" webserver (injectet PHP script) or from "stolen" PC
(zombie PC, zombie network).
Spam NEVER comes from the sender itself. SPAM comes from a stolen account :(
Yes, better knowing the stolen account can help in fix the problem,
linke telling the user to run antivirus/reinstall OS, or the webmaster
to check its .PHP files. But I don't think that identifiyng the user
with X509 cert or some other federated authentication will help.
