I don't think it really matters what the standard is, because you'll be completely limited by some 25 year old bit of Regex from Stack Overflow that every web developer ever has implemented into their form sanity checks.

The main one that gets passed around will match the weirdness fine. In fact, it probably matches things you don't want, anyway.
A signin/registration form really only needs to do sanity checks to get rid of obviously bad addresses. You'll have to send a round-trip email confirmation message to make sure the email is real, anyway, so why bother going into great detail? Just check that there's an '@' symbol and a dot in the domain. Most of the rest is wanking off.

Email addresses can have comments?!
:::wrote last edited by [email protected]Nested comments. RFC822 had a whole bunch of bad ideas in it, but nobody thought much of it at the time. Most programming languages don't even do nested comments, because they want to filter them out with a simple lexer before the grammar ever sees it.

A domaine without tld (me@home) is a valide address.
I saw an email server being used as a mqtt-like server this way (it is very old and predate those software). -

I saw an email server being used as a mqtt-like server this way (it is very old and predate those software).An address without a domain is irrelevant for a signin/registration form. Which is like 90% of the code being written in the wild to validate addresses.
If you're writing an email server, then you need to care about all these details. Most of us never will.

I don't care who the IRS sends, I am not validating emails with spaces on them.

Wow. if I ever have the madness required to self-host, I'll have my email at an IP address.

You shouldnβt be validating emails yourself anyway. Use a library or check for only the
@and then send an email confirmation. -
Same. I answered what i thought was correct and got 14!

I'm gonna have a mailbox per device and the addresses will be deviceip@serverip. [email protected].

I don't validate emails, I test them.
That's your email? OK, what did we send it? if we couldn't send to it or the user can't read it there's no reason to accept it.
OK, maybe I do some light validation first, but I don't trust the email address just because it's email-address-shaped.

Needs to be IPv6, including support for subnets to message multiple devices

What kind of "light validation"? I'm guessing a
.*@.*regex match. -

If qoutes are removed and internal spaces are invalid, how could
":(){β£:|:&β£};:"@example.combe valid? -

Hey! IPv6 is valid in the inter-network context and needs no dots!

You gonna fill an IPv6 address for your email server into the DoorDash signin page?
