1982 was before most people had access to the Internet or email
Compared to today that is true but the time-line is that IBM released the PC 19
1980, Apple the MAC in 1984 (remember the advert?). IBM officially released the
Ethernet card in what? 1984/5, I was at one of the release presentations in
Toronto. Apple had Ethernet long before IBM officially had it. The saw

1n 1982 I was working for a company porting UNIX to the (various) PCs that were
coming out. We had a commercial internet connection, via a couple of
universities, as well as supply UUCP connections to to all the employees who had
PCs and a few dozen other 'friends and relatives' of the company. In those
there were millions of students with email and NNTP accounts at or via
universities. UUCP was available for PCs as well.
There were actually quite a number of non-university/commercial sites such as
The Law Society of Upper Canada.
Then there were bulletin board!
AND set up CO+RE to officially do what DARPANET had already done at that was
assume commercial nodes.
Well before the end of the 1980s there were many version of UNIX, SCO being the
most popular, running on PC machines.
and smtp was used between host computers using smtp
only. There weren't a
lot of PCs doing email in those days.
Not as SMTP, but using BBS and using UUCP, well, that's is a different matter.
At work, back then, we did email on a
VAX 11/780, using terminals to connect to the VAX. The pop rfc is over 2
years newer than smtp. So, back in those days, email generally meant people
using terminals to a shared Unix system, with smtp transfering mail between
systems. Mail with a system didn't need smtp or pop. There were also
commercial networks such as Compuserve, Telenet, etc. that did email, but
they were all proprietary. The company I worked for provided Telenet in
Canada. Even then, it wasn't until 1989 that I used a PC for email.
OK, so I had access to experimental and delivered UNIX on PCs and PC-like
machines and IP on Apples before then. I know I was not alone in this.
The use of port 25 persisted well after CO+RE into the early days of the Global
Internet. During this era Canada was de-regulating the phone service and there
were a lot of 3rd party supplies. In 1988 I saw one or these, Fhonorola out of
Ottawa, act as a Canadian replier of ANS's CO+RE service and got an experimental
56K link to my basement and was one of the first e-commerce business in Ontario
by 1990. As the universities dropped their UUCP accounts for old IT students we
took the supporting them instead. Dial-up IP was still experimental. but there
must have been, all in all perhaps the better part of 1,000 UUCP nodes in the
Greater Toronto area, talking to each other, talking to the universities,
talking to their employers, and as the commercial Internet emerged to the number
of ISPs that were appearing.
All the while SMTP was using port 25 and a lot of the smaller machines became
clients. I recall in 1992 hold a email conversation using telnet on port 25
with a contact at Cambridge university in the UK in near real-time. But yes,
most people were using client and many were using email accounts at their ISP's
server. Webmail was yet to evolve.
Then the Gold Rush happened.
The thing about a Gold Rush is that it is rarely the miners and prospectors that
get rich, and only a few of their immediate suppliers survive in the long run,
though a few might make a packet if they know when to get out. No, there are
really only two groups who make it big during the Gold Rush: the bankers and the
scam artists, the con men.
OK, if there's a government to bail them out then the banks always make it big.
And a lot of con men relay on inadequate proof of identity or credentials.
Which using port 25 and the basic SMTP protocol allowed.
So it is in the class of "yes it used to be but we changed all that".
And the process of tightening up email identification and authentication to
fight spam in its various forms is an ongoing battle.
