I scored 16/21 on https://e-mail.wtf/ and all I got was this lousy text to share on social media.

This was fun!

Edit: people, upvote the OP, not me

[irish_link@lemmy.world]

THIS THING IS STUPID!!!!

Or it’s just me that is the fool. Thanks for sharing. I just learned about 9 new things.

I got 14/21

[lemmyng@piefed.ca]

13/21 here. Mostly got hung up on several "this was valid in earlier RFC, and later removed" kind of situations. There are several where I picked the correct answer, but where I know many websites that won't accept it as valid, and that's not even the more esoteric ones.

Jesus effin Christ! I had no idea!
This is madness! This is ...
Omfg
I just can't

Try explaining that last one to someone over the phone

[db0@lemmy.dbzer0.com]

Yay! Same. But only because I've already heard of some email craziness before.

Going to have to try some of those.... Can you actually register emojis as a domain, or is that just the email validation that allows them?

Edit: most TLDs don't. Smaller ones do sometimes.

All of the modern internet is built on the decaying carcasses of temporary solutions and things that seemed like a good idea at the moment but are now too widely used to change.

[redjard@lemmy.dbzer0.com]

yay 16/21 club

[naiboftabr@infosec.pub]

Yeah I feel like the correct answer for anything obsoleted by a more recent RFC should be "Invalid".

[naiboftabr@infosec.pub]

#18 seems really bad, like no-one-has-ever-sanity-checked-this bad.

[dumnezero@piefed.social]

Thanks to RFC 6532, Zalgo text is a-okay.

hmmm...

Yay! You're average! Time to start making plans for what you'll do when an LLM takes your job.

I already have plans.

I can't even view it...I get a TLS error

This is the score you get when you answer "valid" for every question. Good job.

[neatnit@discuss.tchncs.de]

Emoji domains can be registered using punycode, and you're right that it's up to the TLD whether they're allowed or not.

For example: http://.la/

.la is encoded using punycode to http://.la/

is URL-encoded to %F0%9F%90%B6

Giving the 'true' URL http://.la/ which then redirects to https://emojipedia.org/dog-face

Emails should generally use @xn--yt8h.la instead of @📙.la for maximum compatibility. I'm not sure if the email spec allows punycode.

[zwerg@feddit.org]

Im still trying to figure out what that means. How does @ resolve to an IP address?
