And this right here is a great example of why simple basic RegEx is rarely adequate

I’m like 99% sure I missed at least a few cases there, and will say “please don’t use this for anything production”

  And this is exactly why I wouldn’t do my own, I had no idea either of those were legal/possible

    To be fair nor do most email providers! It’s in the spec, though.
