  As soon as I read the OP's comment I knew someone would reply to say the dot was not technically required, but I didn't expect to see an actual publicly addressable example!

    I actually searched and was surprised no one beat me to it.

  I've read this more than once, and it basically always boils down to: "The only way to verify an email address is to send an email to it." In my opinion, the optimal validation is soft validation: "your email address doesn't look right, continue with it?"

And then hope the server's e-mail workflow can handle subaddressing because you entered in something like "username+service@gmail.com". Seems like a lot of folks don't like '+', even though it's been part of the e-mail system since the 1980s.

  ok, impressed. Happily the mail gem will see that as a valid address :)

  Yep. Back in university I was acquainted with the fellow who set up the MX record for .ai (and assigned himself the memorable address n@ai). IIRC he was involved in planning an academic conference to be held there.

    For the record, it is owned by Anguilla (in the Caribbean): * https://en.wikipedia.org/wiki/.ai https://en.wikipedia.org/wiki/.ai

    Yeah I met him once. I didn't want to call him out on it :)
