What i find interesting about this article is not the realization that MPI is like email, but the reverse, that human collaboration using messages is like MPI. The suggestion to use SMTP as a transport for things much more complex than emails is something worth looking at. It relates to my belief that the instant messaging difference does not come from the new protocols like XMPP for jabber, but from the new client interface that facilitates short messages in a conversational style. SMTP is equally (if not more) capable of transporting these messages. Sure, SMTP is not designed for "instant" messaging. but todays use of SMTP where my local SMTP server talks directly to your SMTP server, makes email is just as instant.

Maddy Mail Server implements all functionality required to run a e-mail server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS).
