The history of email

My first access to “the internet” was through a dialup modem on a VAX at the FDA. I was a summer intern there through my college career and then worked full time after graduation and before grad school. My email address ended in .bitnet. I could mail some places but not others. One of the places I couldn’t send mail was to my friends back on campus.
A few of those friends were computer science majors, so one weekend they tried to help me troubleshoot things. . There were text files that they ended up searching through looking up how to send mail from .bitnet to .edu. But it was all a baffling experience. Why couldn’t it just work? I had email, they had email, why could we not talk?
I never did figure out how to send email to campus from .bitnet.
Eventually, the FDA moved from BITNET to the internet and I had a .gov address. I could send mail around just by getting the recipients’s address. But the mystery of why I could mail some .edus and not others still lingers. I wonder what our setup was that we couldn’t send mail. I’ll probably never know. I don’t even have enough details to explain the problem to someone who would know. I suspect the answer will be “bang paths” or “host.txt” files, but I really don’t know.

That’s one of the reasons I like reading articles about email before SMTP and before email clients. Today’s article was The History of Email posted by Zach Bloom at eager.io. Some things I knew, like how a line starting with the word From had to be escaped (although typically the client handled that). And that mutt is the mail client that sucks less. (I miss mutt, and still use it occasionally for bulk IMAP functions.) Some things I didn’t know, or didn’t remember. It’s possible I used MH back on that old VAX. It certainly wasn’t mutt or pine we used.
It’s an article well worth a read just to learn about the people who created SMTP. We’re also lucky that some of the folks named in the articles are still around and are still contributing to the life and growth of email. Their knowledge and institutional memory helps us map out the future.

Why care about email?

I got my first email address in the very late 80s. I was an intern at a government agency. I learned a lot there: how to sequence DNA, how to handle radioactive material, how to handle human pathogens, and how to send email. I got my first non-work non-school address in the mid-90s. One of the first things I did was join some mailing lists.
One of them was a list for folks who had pet rabbits. I met a lot of people there, both online and in person. As with many people we meet through a shared interest as our interest wanes the relationships change. Some relationships were maintained, but some of us lost touch with one another. Moves, job changes, email address changes, they all affect our ability to maintain relationships online. I kept in touch with some, one was the maid of honor at my wedding and a few years ago I was the maid of honor at hers. I lost track of others.

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.

Confusing the engineers

We went camping last weekend with a bunch of friends. Had a great time relaxing on the banks of the Tuolumne River, eating way too much and visiting.
On Saturday I was wearing a somewhat geeky t-shirt. It said 554: abort mission. (Thank you MessageSystems). At some point on Saturday every engineer came up to me, read my shirt and then looked at me and said “That’s not HTTP.”
That lead to various discussions about how their junior engineers don’t actually know SMTP at all. Why? Because the SMTP libraries just work. Apparently the HTTP libraries aren’t that great, so folks have to learn more about HTTP to troubleshoot and use them.
I’m sure there’s a joke in there somewhere: A Kindle engineer, an Android engineer and a robot engineer walk into a campsite…
EmailFilters_boxes_forblogIt did leave me thinking, though, about how it’s not that easy to run your own mail server these days. Gone are the days when running your own server was cost effective and easy. These days, there is just too much spam coming in. Crafting filters is a skilled job. It’s not that hard to run good filters. But to run good filters takes time to do well.
There are also a lot of challenges to sending mail. One of the discussions I had at the campsite was how hard it was to configure outbound mail. The engineer was helping a friend set up a website and trying to get the website to send notifications to the friend. But without setting up authentication the mail kept silently failing.
Of course, we do run our own mail server. But it’s our job and, in many ways, it keeps us honest. We don’t run many filters meaning we see what spammers are doing and can use our own experiences to better understand what commercial filters are dealing with.
For most people, though, I really think using a service is the right solution. Find one with filters that meet your needs and just pay them to deal with the headache.
