What it doesn???t tell is the real story of email as we use it today. That story starts with RFC 821, by Jon Postel, posted in August 1982. It begins,The objective of Simple Mail Transfer Protocol (SMTP) is to transfer mail reliably and efficiently.SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.
What makes SMTP so useful and universal today is that it intentionally transcends any intermediator???s silo or walled garden. It simply assumes a connection. So do the POP (RFC918 and IMAP (RFC1064) protocols (used at the receiving end), for which the relevant RFCs were issued in 1984 and 1988.
Those protocols ended up winning ??? for all of us ??? after it became clear that their simplicity, and their oblivity to the parochial interests of network owners and operators, were what we really needed. That was in 1995. In the meantime, a pile of proprietary and corporate email systems competed in a losing battle with each other. Compuserve, Prodigy, MCI Mail, AppleLink, and a host of others were all obsoleted by the obvious advantage of having nobody own the means by which we simply send electronic mail to each other.
Forget the corporate green washing and smug self back patting, here’s the real story.
