Personally I'd be very much in favour of the two-layer system hinted at
by that paper. This is the new design I have in mind:
MUA -> mails through SMTP server ("IMX") on port 587 using SASL auth
IMX is SPF-approved for the domain, and can mail to any MX
MX performs SPF checks, accepts the mail, saves to a mailstore
mailstore serves the message to the user over IMAP/POP/mutt, etc
It's actually very similar to what we have today, except for the 587 and
SPF parts.
