About dark-themed email clients: the most important thing, designers must remember: its unacceptable to define color just for fonts or background. If you are altering colors, you MUST specify BOTH of them: background AND foreground. Both or neither! Because you dont know whick colors are default in viewer.
You also don't know which one the customer's software is configured to override. Could be both, even. So even if you specify both it could look totally different.
I'm a dinosaur, and I had all my system colors set to a custom dark theme back in the Windows98 to XP days, before it became a thing. Easily 75% of web form input fields had the color or background explicitly set to the default black and white, respectively. This made everything white on white or black on black. This was so irritating, and I dealt with it for years. Thankfully things improved.

23:33 small correction, Protonmail has the same feature as Gmail, you can add "aliases" after + sign before @ sign and they all will all effectively redirect mail to the same address
I noted that discrepancy too; "sending" would of course work if he registered "rocket" and then just addressed rocket+whatever, but I suppose the point of the segment was to show that a MAILBOX cannot have a "+" in, and he didn't want to (=strictly, one can claim "shouldn't be forced to-") register just a single word address. Brings up another question: does it still map +x to "Label: x" in the GMail app, and does +x+y+z map to "Label: x", "Label: y", "Label: z"?
Each time I see one of your talks online, I am ever more impressed with just how much of a wealth of knowledge you offer, and I thoroughly enjoy learning from you!
The number of sites that still reject Gmail plus aliases when setting up accounts is disappointing. For that matter, the "canonical" form of my gmail address has a period in it, and some sites even reject that.
@@techtutorvideos No way you did that, all special characters are removed on gmail. If you have dots on your email, your email is the same without the dot, and as the video explained, the + is used just for alias.
Amazing talk through and through, with one remark: 55:40 this is misleading because Gmail is such a behemoth in the mail world that it's starting to setup standards that everyone has to comply with.
Using plus '+' in an email address is not unique to Google. Office 365, Protonmail and Fastmail all support using plus in the email address the same way. (I am not sure about Zoho mail because I have never used it)
The Protonmail *signup* results (not the sending results) make sense if you remember Protonmail is supposed to be some kind of secure service so it probably puts an emphasis on not allowing weird things just in case. At 28:46 you made a big mistake - you DID ask the Zoho server to relay mail to the Protonmail test domain (pm) instead of sending directly to the Zoho test domain (zh)
@@DylanBeattie what happened after the video cuts? did you talk about Gmail, Azure, AWS, etc? or did you sacrifice someone's first born child? or was it a round of questions? if the latter, thank you, I hate when uploaded lectures/talks have those xD
ProtonMail supports plus addressing too, they just call it "+alias". Also they have this feature called "catch-all address" which is a more general version of the same thing, because every address you didn't already register for that domain will be delivered to the catch-all address instead. For example single apostrophe and underscore works just fine, though single dash doesn't.
16:13 I thought he was going to use the keyboard layout as an example. The common staggered qwerty layout is unwieldy and inferior to a non-staggered layout, but we keep the staggering for people who are used to using old typewriters. And those typewriters needed the staggegering because otherwise the hammers would get in each others' way. The staggering is also a case of backwards compatibility reaching insanely far back into the past.
I started my career in the 1990s and did a lot of work with email of various types. At that point, RFCs didn't always carry a lot of weight. People just did what worked for them. Lots of things tended to comply with some of the RFC, but often omitted parts or added proprietary extensions. The original SMTP RFC contained a bunch of dumb stuff (like quotes and comments) that very few people bothered to support. Also, bang paths.
The guy who said "The net interprets censorship as damage" being universally censored by the Internet at large is hilarious and depressing in equal measure.
One of the best things about this lecture is that I finally understood why I have ALWAYS hated HTML e-mail, and up to this day, forcing plaintext mail is the first thing I do when I set up a mailer. I never really knew why I hated them. But when I heard "table within a table within a table", I knew that even without knowing exactly why, my coder brain just knew it was crap. Thanks, Dylan :)
I am always looking forward to the next piece from Dylan.. I'm not even in the tech field but modestly tech savvy and enjoy the humor and education in each one, everything from Rock star programming to the Art of code
Hold on. DNS in 1983? It wasn’t in widespread use. I was a student operator in the digital computer laboratory at the university of Illinois in 1983. At that time our “network” connection was a 9600 baud modem to Purdue twice a day, in which we sent 2 MB or so of email and Usenet postings per connection. Some time later, we got an always on connection of… not sure, 56 kb? Anyway, for years I was typing in all sorts of arcane email paths to send messages. Thank god for ihnp4, which was a gateway to everything! DNS wasn’t adopted for quite some time. The hosts file grew to some 1.2 or maybe 2 MB by the time DNS was rolled out. I was disappointed, because it meant that I wouldn’t be able to look up (grep) for any host I wanted from the hosts file. Of course, it also meant that a single entity couldn’t claim a name that nobody else could use😂. Anyway, I maintain that 1983 was too early for dns to be used. No one was using it, that I was aware of.
I have just tested... Sending from the work 365 mail I could single-apostrophe-at my personal domain, and... I did get it. From now on, this is the address I am sharing with people.
Finally a nice overview on e-mail. Thanks! I set up my own mail server one time but dealing with Microsoft and google was just too much, especially because I didn't know enough about what I was doing.
23:30 Proton mail supports subadressing (that + thing in local part), and office365 does it as well - thus you cannot use + character in standalone email address...
You know a talk is truly excellent and the presenter is an engaging speaker when you're already familiar with all of the concepts being communicated but you still watch the full hour and love every minute of it. Amazing work, Dylan!
Email subaddressing with the plus sign in local part was in use long before Gmail even existed, at least since the late 80s/early 90s by the Andrew system at Carnegie Mellon. Source: I'm old. PS: Oh, regarding it not being "part of email standard" you are basically right, but as with many Internet standards, it's complicated. RFC 5233 describes subaddress filtering, including "One common way of encoding 'detail' information into the local-part is to add a 'separator character sequence', such as "+", to form a boundary between the 'user' (original local-part) and 'detail' sub-parts of the address, much like the "@" character forms the boundary between the local-part and domain."
At 36:16, you said that in the original SMTP spec, methods could have been used to better track senders and include spam protection in the standard itself. Do you have examples of such methods or ideas that could have been implemented ?
49:00 seriously considering parsing HTML e-mail because looking through that crap gets tedious. I have been resisting HTML e-mail because I feel it weakens any security guarantees of signed messages (since different clients render HTML differently).
HTML mails were/are huge mistake... Usually doesn't even deliver on the look-good side, and ruined so much stuff. Just because some people think using few extra asterisk and ascii-art tables is NOT enough to emphasise text. :( (also my email client renders them in a way you wouldn't expect if you haven't been using text terminal ever in your life... yes, I'm reading my emails in text mode with alpine email client and html mails are sort of stripped down to text-only form for me, in nice green font over black background of text terminal)
@@ped7g When I was still on dial-up lynx was my favorite browser. It was like 5x faster than any other browser because it was not downloading superfluous crap. I finally moved to graphical browsers in the 2010's.
Awesome presentation! On the last point about corporations owning WhatsApp, Telegram, etc, could the ActivityHub be the email equivalent for modern communication needs?
I remember manually assembling mime into files, sometimes waiting quite a while for the middle bits of the email to arrive because I was down the FAR end of a long ! path.
I love that I jumped when I received an email during the beginning part where he was saying "ok, you're getting an email now". I hate that I was jump-saddened by Young Matty Perry at 33:54.
17:22 Most naive email regexes in Stackoverflow would probably match the first two, sometimes the third and fourth too. But when I when I first considered the problem of validating email addresses I realised that the spec allowed so much the only thing I really could be sure of was that a valid email contains an @ symbol and at least one character before and after it. But of course then the clients complained that it accepted "somename@gmail" etc. without the top level domain; so I decided that it was better to add another technically incorrect requirement that an email should have at least one period with at least one character before and after that period in the host name part; with the assumption that anyone who legitimately have an email without any periods in their host name is probably much rarer than idiots who forgets the top level domain name of their email. So whenever I have needed to make my own email validation; it would usually accept all of these except the ipv6 one.
I have ME/CFS. Dark mode allows me to continue to do stuff with computers. Big areas of bright lit pixels like white backgrounds makes me tired faster.
I have no reason to have enjoyed this talk as much as i did. I'm not a developer, programmer, hell i can't remember the last time i opened an email client. But this talk was very interesting.
There are actually quite a lot of companies that do render your email on all possible variations on read devices, it cost quite a bit, but it gets as close to complete as possible
Hands down my favourite lecture of Dylan. Seemingly obscure, but full of actually fascinating stuff and totally fun. 33:20 "E-mail was invented by hippies. And hippies SUCK at security." XD
Plus sign in email addresses is *NOT* a gmail/google specific feature, it is an *EMAIL STANDARD* specified in RFC 5233 (from January 2008) that was originally specified in the now obsolete RFC 3598 (from September 2003)... google/gmail just happens to be one of the big email providers which happened to support it first but more tech savvy people have ben using it for years (on sites which supports it, not all sites consider an email address with a plus sign valid)...
I recently created a web game and after long consideration about how email was going to be used to verify accounts, I decided it wasn't. I just use other metrics to try and detect bad actors. Many services use SMS codes instead of email for login now and I can see why. The whole thing's a nightmare and despite being simpler than the web on paper, it's infinitely more complex to run a mail server or send mail than to run a web server and host a website.
I had that moment. Client never got any emails, finding that we changed our mail provider and I forgot to update then smtp client details on our backend lol
I'm just now releasing a new email service called Port87 and this talk made me feel like I have PTSD. You described basically every annoying little thing I learned in the past two years working on this project. But I can say, it is possible for a single person to develop a new email service in 2023, and that is what's amazing about email.
Indeed it is. I made one a month ago on a rainy saturday. It was decent fun but not challenging enough. So while I was making the e-mail service I also decided to write a new OS for my personal use. The operating szstem I made that day is decent, but it only runs software made for GNU/Linux, OSX, Windows, DOS, OS/2, PDP11, CADR, Android/Linux, GNU/Hurd, and a new system which will be released in the future but is too advanced for current usage. I also made a few other things that day but I have no time to talk about them because while typing this comment I am writing an emulator that emulates every gaming console released between 2000 AD and now with perfect accuracy and so fast it can run them all at once on 1980 hardware and the emulator is almost finished.

Seriously, I will never understand how people are happy with bright backgrounds. Everything should be dark by default, and then for reading long texts or in bright sunlight one should simply invert the colours and use e-ink displays.
I would love if our national TV dr.dk would enable dark mode. You sit in your cosy living room with dimmed light, select their app, and bam!! 60" of #FFFFFF blinding light with a tiny logo fills the entire room.

The person uploading this: "Now, that's where you're wrong"
It does end there, it ends exactly there. Was it cut down after the fact?
@@IanBLacy It used to not end there. They must have edited it. I don't remember a thing of what he said after this point though
@@Keisuki Nooooooo 😢 I gotta look for the recordings elsewhere I guess :((
Was kinda curious why nobody's commenting on the cut tho
and this is why corporations are having so much trouble figuring out how to create their own 'metaverse' that only they can own. Because the baseline of all of our primary communication methods has been free for anyone to use.. And they have to somehow compete with that.
As a dev, it would maybe be beneficial to have some standards that finally update and drop the cassette tape. But as an end user, why?
Drop the cassette tape?
@@entx8491 16:25
The other reason they’re having trouble getting a good meta verse is because the concept is inherently flawed
.... no.
Metaverse as a concept is flawed from the beginning...
A centralized service that you interact with through an avatar? Well, I can tell you that shopping online is generally more efficient than walking around a store... Because... I can't search, I can't scroll fast through a list, etc
Metaverse is trying to do the inconveniences of real life and add it to the internet
Dylan is amazing at teaching. I know nothing about this but could follow along and enjoy. Really powerful skill
23:33 small correction, Protonmail has the same feature as Gmail, you can add "aliases" after + sign before @ sign and they all will all effectively redirect mail to the same address
I noted that discrepancy too; "sending" would of course work if he registered "rocket" and then just addressed rocket+whatever, but I suppose the point of the segment was to show that a MAILBOX cannot have a "+" in, and he didn't want to (=strictly, one can claim "shouldn't be forced to-") register just a single word address. Brings up another question: does it still map +x to "Label: x" in the GMail app, and does +x+y+z map to "Label: x", "Label: y", "Label: z"?
Each time I see one of your talks online, I am ever more impressed with just how much of a wealth of knowledge you offer, and I thoroughly enjoy learning from you!
The number of sites that still reject Gmail plus aliases when setting up accounts is disappointing. For that matter, the "canonical" form of my gmail address has a period in it, and some sites even reject that.
@@techtutorvideos No way you did that, all special characters are removed on gmail. If you have dots on your email, your email is the same without the dot, and as the video explained, the + is used just for alias.
Amazing talk through and through, with one remark:
55:40 this is misleading because Gmail is such a behemoth in the mail world that it's starting to setup standards that everyone has to comply with.
Whatever the subject is, I know I'm gonna have a great time watching your presentations
Using plus '+' in an email address is not unique to Google. Office 365, Protonmail and Fastmail all support using plus in the email address the same way. (I am not sure about Zoho mail because I have never used it)
Zoho supports plus as well.
It's called "the sendmail hack" because it's that old
The Protonmail *signup* results (not the sending results) make sense if you remember Protonmail is supposed to be some kind of secure service so it probably puts an emphasis on not allowing weird things just in case.
At 28:46 you made a big mistake - you DID ask the Zoho server to relay mail to the Protonmail test domain (pm) instead of sending directly to the Zoho test domain (zh)
Ooops.
@@DylanBeattie what happened after the video cuts? did you talk about Gmail, Azure, AWS, etc? or did you sacrifice someone's first born child?
or was it a round of questions? if the latter, thank you, I hate when uploaded lectures/talks have those xD
ProtonMail supports plus addressing too, they just call it "+alias". Also they have this feature called "catch-all address" which is a more general version of the same thing, because every address you didn't already register for that domain will be delivered to the catch-all address instead. For example single apostrophe and underscore works just fine, though single dash doesn't.
Excellent talk. Very entertaining AND very informative.
Awesome presentation, very lively and informative! 🔥
16:13 I thought he was going to use the keyboard layout as an example. The common staggered qwerty layout is unwieldy and inferior to a non-staggered layout, but we keep the staggering for people who are used to using old typewriters. And those typewriters needed the staggegering because otherwise the hammers would get in each others' way. The staggering is also a case of backwards compatibility reaching insanely far back into the past.
I started my career in the 1990s and did a lot of work with email of various types. At that point, RFCs didn't always carry a lot of weight. People just did what worked for them. Lots of things tended to comply with some of the RFC, but often omitted parts or added proprietary extensions. The original SMTP RFC contained a bunch of dumb stuff (like quotes and comments) that very few people bothered to support. Also, bang paths.
Hey! What's wrong with bang paths? (UUCP admin from the early 90s here ;)
Great talk! Had a good laugh, and some flashbacks..
Amazing talk! Useful advice.
And kudos for reminding me of late 90ies when I had to telnet 25 to quickly check mailserver works.
Thanks for giving me a good time by watching this!
The guy who said "The net interprets censorship as damage" being universally censored by the Internet at large is hilarious and depressing in equal measure.
One of the best things about this lecture is that I finally understood why I have ALWAYS hated HTML e-mail, and up to this day, forcing plaintext mail is the first thing I do when I set up a mailer. I never really knew why I hated them. But when I heard "table within a table within a table", I knew that even without knowing exactly why, my coder brain just knew it was crap. Thanks, Dylan :)
No, Non-dark mode on any site/program/app/screen thingy should be illegal with capital punishments.
Should be as default dark mode
I vaguely want to know what happened after the youtube version ended…
I am always looking forward to the next piece from Dylan.. I'm not even in the tech field but modestly tech savvy and enjoy the humor and education in each one, everything from Rock star programming to the Art of code
Hold on. DNS in 1983? It wasn’t in widespread use. I was a student operator in the digital computer laboratory at the university of Illinois in 1983. At that time our “network” connection was a 9600 baud modem to Purdue twice a day, in which we sent 2 MB or so of email and Usenet postings per connection. Some time later, we got an always on connection of… not sure, 56 kb? Anyway, for years I was typing in all sorts of arcane email paths to send messages. Thank god for ihnp4, which was a gateway to everything! DNS wasn’t adopted for quite some time. The hosts file grew to some 1.2 or maybe 2 MB by the time DNS was rolled out. I was disappointed, because it meant that I wouldn’t be able to look up (grep) for any host I wanted from the hosts file. Of course, it also meant that a single entity couldn’t claim a name that nobody else could use😂. Anyway, I maintain that 1983 was too early for dns to be used. No one was using it, that I was aware of.
Beautiful spam choir!
Excellent talk, Dylan. Thank you.
Really insightful piece. And wonderful delivery
I think plus addressing predates gmail by some years. It is supported in sendmail starting with version 8.7.
I have just tested...
Sending from the work 365 mail I could single-apostrophe-at my personal domain, and... I did get it.
From now on, this is the address I am sharing with people.
Ane awesome talk! Thank you so much, I am very amused and a lot more informed now :)
Hey! You forgot IRC as an open protocol for communication :)
Nice talk, liked it, was very informative. Now I understand raw mail!
Finally a nice overview on e-mail. Thanks! I set up my own mail server one time but dealing with Microsoft and google was just too much, especially because I didn't know enough about what I was doing.
Wonderful talk and good history lesson.
This talk should be compulsory viewing. OMG. So packed with critical context about how things work in Internet land.
Great talk, as someone who has to deal with e-mail, troubleshooting clients writing mail templates sometimes It truly is a pain to work with.
Super informative and entertaining!!!
23:30 Proton mail supports subadressing (that + thing in local part), and office365 does it as well - thus you cannot use + character in standalone email address...
You know a talk is truly excellent and the presenter is an engaging speaker when you're already familiar with all of the concepts being communicated but you still watch the full hour and love every minute of it. Amazing work, Dylan!
Email subaddressing with the plus sign in local part was in use long before Gmail even existed, at least since the late 80s/early 90s by the Andrew system at Carnegie Mellon. Source: I'm old. PS:
Oh, regarding it not being "part of email standard" you are basically right, but as with many Internet standards, it's complicated. RFC 5233 describes subaddress filtering, including "One common way of encoding 'detail' information into the local-part is to add a 'separator character sequence', such as "+", to form a boundary between the 'user' (original local-part) and 'detail' sub-parts of the address, much like the "@" character forms the boundary between the local-part and domain."
At 36:16, you said that in the original SMTP spec, methods could have been used to better track senders and include spam protection in the standard itself. Do you have examples of such methods or ideas that could have been implemented ?
Noooo I need to know what happened after the live stream. I need closure on the anecdote.
49:00 seriously considering parsing HTML e-mail because looking through that crap gets tedious.
I have been resisting HTML e-mail because I feel it weakens any security guarantees of signed messages (since different clients render HTML differently).
HTML mails were/are huge mistake... Usually doesn't even deliver on the look-good side, and ruined so much stuff. Just because some people think using few extra asterisk and ascii-art tables is NOT enough to emphasise text. :(
(also my email client renders them in a way you wouldn't expect if you haven't been using text terminal ever in your life... yes, I'm reading my emails in text mode with alpine email client and html mails are sort of stripped down to text-only form for me, in nice green font over black background of text terminal)
@@ped7g When I was still on dial-up lynx was my favorite browser. It was like 5x faster than any other browser because it was not downloading superfluous crap.

Awesome presentation! On the last point about corporations owning WhatsApp, Telegram, etc, could the ActivityHub be the email equivalent for modern communication needs?
I remember manually assembling mime into files, sometimes waiting quite a while for the middle bits of the email to arrive because I was down the FAR end of a long ! path.
By the way + tagging is supported by all of them, not just google.
I'm confused by the title email vs capitalism. Is it because capitalism caused the spam? or was there something else I missed?
I love that I jumped when I received an email during the beginning part where he was saying "ok, you're getting an email now".
I hate that I was jump-saddened by Young Matty Perry at 33:54.
I guess I need to watch more of his videos, glad I stumbled upon someone talking about him on Reddit.
17:22 Most naive email regexes in Stackoverflow would probably match the first two, sometimes the third and fourth too. But when I when I first considered the problem of validating email addresses I realised that the spec allowed so much the only thing I really could be sure of was that a valid email contains an @ symbol and at least one character before and after it. But of course then the clients complained that it accepted "somename@gmail" etc. without the top level domain; so I decided that it was better to add another technically incorrect requirement that an email should have at least one period with at least one character before and after that period in the host name part; with the assumption that anyone who legitimately have an email without any periods in their host name is probably much rarer than idiots who forgets the top level domain name of their email.
So whenever I have needed to make my own email validation; it would usually accept all of these except the ipv6 one.

I have no reason to have enjoyed this talk as much as i did. I'm not a developer, programmer, hell i can't remember the last time i opened an email client. But this talk was very interesting.
There are actually quite a lot of companies that do render your email on all possible variations on read devices, it cost quite a bit, but it gets as close to complete as possible
Hands down my favourite lecture of Dylan. Seemingly obscure, but full of actually fascinating stuff and totally fun.
33:20 "E-mail was invented by hippies. And hippies SUCK at security." XD
Best talks in the business, hands-down.
I watched to the end, now I have to know... what was it that didn't come on to youtube????
Plus sign in email addresses is *NOT* a gmail/google specific feature, it is an *EMAIL STANDARD* specified in RFC 5233 (from January 2008) that was originally specified in the now obsolete RFC 3598 (from September 2003)... google/gmail just happens to be one of the big email providers which happened to support it first but more tech savvy people have ben using it for years (on sites which supports it, not all sites consider an email address with a plus sign valid)...
Summer of Love was 1967 (nice metaphor though)
Extremely useful info. Thanks!
Thank you, that was very interesting. I thought you might touch on pgp and gnupg and why nobody ever mandated that system (as far as I'm aware).
I recently created a web game and after long consideration about how email was going to be used to verify accounts, I decided it wasn't. I just use other metrics to try and detect bad actors. Many services use SMS codes instead of email for login now and I can see why. The whole thing's a nightmare and despite being simpler than the web on paper, it's infinitely more complex to run a mail server or send mail than to run a web server and host a website.
Fantastic talk! So good! :)
Great talk! Still feel like it should have tried to sell me something because that's the web now.
Not in the places I hang out.
Pretty sure there's a generation gap between when computers stopped using cassette tapes and when PowerPoint was created in 1990.

This is one of the best tech talks I’ve seen.
I've seen a few providers support the + tagging method, it's a very useful feature I wish was made standard.
Amazing!
Great talk.
The + character in the local part of an address seems to have been described in the 2008 RFC 5233.
Wow this is a great talk 👏
Great talk as usual @DylanBeattie
One thing - Microsoft have the same +tag tracking on 365 23:26
As he said "We are now going to send you an email" I got a notification for an email being sent... Just about crapped myself
38:12 if you also wanted to know what it was that is base64-encoded there: it is "funwith:email", so a colon between login and password.
13:42 OK we all, the entire internet formally agree to never send spam. Amen.
2023 what absurd big number of bytes spam per second ?
About 53:46 : Dark mode is the original default *and* an accessibility feature. It's bright mode that should never have been allowed to happen.

38:50 Such a powerful quote given the ad-blocker ban situation in RUclips.
I'm just now releasing a new email service called Port87 and this talk made me feel like I have PTSD. You described basically every annoying little thing I learned in the past two years working on this project. But I can say, it is possible for a single person to develop a new email service in 2023, and that is what's amazing about email.
Indeed it is. I made one a month ago on a rainy saturday. It was decent fun but not challenging enough. So while I was making the e-mail service I also decided to write a new OS for my personal use. The operating szstem I made that day is decent, but it only runs software made for GNU/Linux, OSX, Windows, DOS, OS/2, PDP11, CADR, Android/Linux, GNU/Hurd, and a new system which will be released in the future but is too advanced for current usage.
I also made a few other things that day but I have no time to talk about them because while typing this comment I am writing an emulator that emulates every gaming console released between 2000 AD and now with perfect accuracy and so fast it can run them all at once on 1980 hardware and the emulator is almost finished.
But the enddddd
What did they cut off in the endddddddd
This talk is not compatible with my device!! (technically)
For the O365 SMTP telnet connection you probably needed to create a connector for your domain.
This is an amazingly interesting talk.
I'm fairly certain you can use the format: host!user... (Yes, I've edited the notorious sendmail configuration file)
awesome as always!
I wish I had seen this before I tried to roll my own email server and then spent a week bumping into all the ways that's a bad idea.
