I kind of expected a lot of this; I remember the sendmail 4 book from back in the day when O'Reilly had that, DNS and BIND, and Perl as the entirety of its corpus.

In response to your edit.
Yes, or countries could use their cctld, e.g. email@us or noreply@uk.
Or any tld owner could do the same with theirs, of course.
Pretty cool

That's one very random place to find that. There are a lot of different one and there is no way we all just agree to use that one.
Look art his site that shows a more complete and (in theory) official website. While also explaining that there is no regex that is perfect
(Compete regex for the lazy)
(?:\[a-z0-9!#$%&'\*+/=?^\_\`{|}\~-]+(?:\\.\[a-z0-9!#$%&'\*+/=?^\_\`{|}\~-]+)\*|"(?:\[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\\\\[\x01-\x09\x0b\x0c\x0e-\x7f])\*")@(?:(?:\[a-z0-9]\(?:\[a-z0-9-]\*\[a-z0-9])?\\.)+\[a-z0-9]\(?:\[a-z0-9-]\*\[a-z0-9])?|\\\[(?:(?:25\[0-5]|2\[0-4]\[0-9]|\[01]?\[0-9]\[0-9]?)\\.){3}(?:25\[0-5]|2\[0-4]\[0-9]|\[01]?\[0-9]\[0-9]?|\[a-z0-9-]\*\[a-z0-9]:(?:\[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\\\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\\])MDN isn't a very random place?

MDN isn't a very random place?
No. But it's on the form validation topic.

I'm not sure I blame the sites. The spec is so complex that it's not even possible to know which regex to use

Yes. Almost like a regex is not the correct tool to use, and instead they should use a well-tested library function to validate email addresses.

13/21, seems like I am not significantly different from random guessing
I got 11.
The spaces and quotes caught me. -

I have a feeling, the ones codapine is stating, didn't even care to half-read the spec and just went with what they knew from experience.
Maybe they didn't even know there was a spec.
Maybe they asked ChatGPT for the regex. -
No. The number of users who have a real email with no TLD is far less than the number of users who will accidentally type an email with no TLD if you don’t validate on the front end.
I’m here to help 99.9% of users sign up correctly, not to be completely spec-compliant for the 0.1% who think they’re special.
Guess my mail@IPv6 won't be accepted because I was too poor to pay for a domain name after having paid for a static IPv6.

wrote last edited by [email protected]Exactly! But its not obvios. So most of those shitty websites don't even know they have a problem.
Then there are also people ignoring it on purpose. I once read a reddit comment saying 'well of your address looks like "John wick
