I'm locked out of my 6 year old Chipotle account because they now say my email address is invalid when I login. Here is me asking for their help:

sacbuntchris@lemmy.world to Mildly Infuriating@lemmy.world – 1564 points –

I also reached out to them on Twitter but they directed me to this form. I followed up with them on Twitter with what happened in this screenshot but they are now ignoring me.

You're talking to a bot that has a crappy parser and doesn't understand what a subdomain is.

This is why you never attempt to validate an email address beyond requiring an @ followed by a period, and send a verification email

Technically you don't need a period for a valid address. "a@a" is a valid email address.

Not a lot of people sending emails using hostnames nowadays though.

Could be a Tld without a domain in front.

Can you give an example of that?

Ian Goldberg had an email at a TLD in 2002.

I've been working with websites, frontend and backend code for almost 20 years, somehow never knew this was a thing. Weird.

That's really neat. It of course makes sense because I can't see any reason why a TLD couldn't have MX records, but I am surprised that any TLD actually does.

I found an RFC with domains that have MX, A, and/or AAAA records. https://datatracker.ietf.org/doc/html/rfc7085

Yeah, I’ve noticed that a lot of sites are starting to disallow aliasing with email addresses. So annoying.

Which is blatant incompetence considering there is a very straightforward RFC covering domain names.

https://www.ietf.org/rfc/rfc1035.txt

Has anyone followed standards properly? There are weird workarounds in Linux's TCP implementation because they had to do the same non-standard workarounds as BSD which was added since there are too many buggy TCP implementations out there that will break if the RFC is followed to the letter...
