        @nixCraft RegEx, almost always the wrong choice

          @nixCraft One thing I've learned over the years, is never try to validate an email address with regex !

            Copy a relatively good existing one, then just prompt for "are you sure" if it fails to match.

              @nixCraft I think this is the right page from the Necronomicon: (?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])

                  @nixCraft Just take a predefined one from someone else. Creating such complex regex is a waste of time and never totally right 🫠.

                          you shall be cast into the darkness with the regex nought to return until the email be atuned
                          type stuff
                          Or was that a nightmare. . .?

                                    @nixCraft regex might be hard, the email addresses RFC is "wild", cf.

                                    The answer that quiz gives on question 7 is not how I read the RFC. I looked at both RFC 821 and RFC 5321, neither permits spaces in an unqouted local-part.

                                      Did you find the needle in the haystack yet? /s

                                        The answer that quiz gives on question 7 is not how I read the RFC. I looked at both RFC 821 and RFC 5321, neither permits spaces in an unqouted local-part.

                                        I'd think in a dot-atom spaces around the dot would be ok?

                                        That's foo . (Comment) bar @ something . com

                                        At least in "obsolete" syntax.

                                          Probably even with line folds.
