Email History through RFCs

Many aspects of email are a lot older than you may think.
There were quite a few people in the early 1970s working out how to provide useful services using ARPANET, the network that evolved over the next 10 or 15 years into the modern Internet.

They used Requests for Comment (RFCs) to document protocol and research, much as is still done today. Here are some of the interesting milestones.
April 1971 [rfc 114]RFC 114 A File Transfer Protocol.[/rfc] One of the earliest services that was deployed so as to be useful to people, rather than a required part of the network infrastructure, was a way to transfer files from one computer to another. In the [rfc 114]earliest versions[/rfc] of the service I can find it could already append text to an existing file. This was soon used for sending short messages, initially to a remote printer from where it would be sent by internal mail, but soon also to a mailbox where they could be read online.
August 1971 [rfc 221]RFC 221 A Mail Box Protocol, Version-2[/rfc] had this prescient paragraph:

thirty.years.com

Thirty years ago this Sunday, symbolics.com was registered – the first .com domain. It was followed, within a few months, by bbn.com, think.com, mcc.com and dec.com.
Symbolics made lisp machines – symbolics.com is now owned by a domain speculator.
BBN is a technology R&D company who’ve worked on everything. If I had to pick one thing they were involved with it’d be the Internet Message Processor – the router used on the very first Internet nodes. They are still around, as a division of Raytheon.
Think.com made some amazing massively parallel computers. Their hardware group was bought out by Sun, who were bought out by Oracle and think.com now redirects to a broken error page at oracle.com.
Mcc.com were the first – and for a while, the largest – computing research and development consortium in the US. They did groundbreaking work on everything from silicon to AI. Their domain is now a generic parked page owned by a domain speculator.
Dec.com were Digital Equipment Corporation – creators of the PDP, VAX, Alpha and StrongARM processors, amongst many other things. They were a huge company when I worked for them designing Alpha CPUs in the mid 90s, then they were acquired by Compaq, then HP, then split up. Their domain is now a personal website.
It took nearly three years to reach 100 registered .com domains and nearly 10 years to reach 9,000.
As of this morning there are 116,621,517 domains registered in .com, from (64 zeros).com to (64 letter z).com, out of a possible total of more than two googol – so there’s still a domain there for you.
221,848 of those domains in .com mention “mail”.

Ray Tomlinson

Ray Tomlinson has passed away. Mainstream obituaries are going to focus on his being “the creator of email” or “the sender of the first email” or “the inventor of the @ sign in email addresses“.
All of which are true. He did send the first (networked) email. He did use the (otherwise mostly unused on TENEX) @ sign to separate user and host.
But he did a lot of other things with the basics of the modern Internet that are more important than the @-sign.
