Comment on 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:

  Exactly. After the @ they should just confirm there’s at least one period. The rest is pretty much up in the air.

    Which would still be technically wrong. There does not need to be a dot.

    source
  • 0x0@lemmy.dbzer0.com ⁨6⁩ ⁨months⁩ ago

    Even that would be technically incorrect. I believe you could put an A record on a TLD if you wanted. In theory, my email could be me@example.

    Another hole to poke in the single dot regex: I could put in fake@com. with a dot trailing after the TLD, which would satisfy “dot after @” but is not an address to my knowledge.

      And this sort of thing is exactly how you end up with bad regex that invalidates valid emails.

      The point isn’t to invalidate all bad emails. It’s to sort out most of them.

      Something something http://[2607:f8b0:4004:c09::8a] and http://3627734062 are valid url’s without a dot, and are probably valid for emails too, but I’m too lazy to actually verify that.

    I’ve had issues with this in using govt emails too. DOD accounts all have multiple dots based on branch and dept. It broke so many systems and emails never went through.

    The easiest and most correct check: any character, then @, then any other character.

  the only good regex for email validation
