What about @@.@?

• woranl 5y ago
  There is nothing before the first @, and nothing after the last @.

    While that's true, `@@.@` fulfils "an @ symbol with something before it, and something after it".

      The original comment probably meant something like this: ^[^@]@[^@]$
      • mekster 5y ago
        That's only one letter before and after.

  People who have weird email addresses are used to them not working.

  Interesting question. RFC1123 states that TLDs should be alphabetic, and that the first (or only) character must be a letter or a digit, which should exclude a TLD of '@'. local-parts can include most printable characters other than ()<>[];:@\,. /^+@+$/ is easy and the false positives it allows are weird enough to accept.
