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:
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.

Not even a dot: TLDs are valid email domains. joe@google is a correct address.
Mmm... That doesn't seem right, it's usually gotta be fully expanded to at least a particular A record/MX.
How would you tie the tld itself to an MX?
TLD is just another DNS layer, try an SOA or NS lookup for "com." those are obviously hosted somewhere. Hell the "." at the end is even another layer with the root nameservers. You'd probably trip up a bunch of systems that filter on common convention rather than the actual RFC, but you could do it.
How the hell were the original rfc designers so creative as to result in such a flexible system?? It's gets crazier the more you look at it.
It makes the system as a whole simpler. Your computer only needs to remember one root DNS server (although most computers allow setting 4 for redundancy) as opposed to one DNS server for each TLD, and it also makes adding TLDs easier.
