Here’s the regex you should use: .+@.+\..+ Works every time 100% of the time.

  Haha I like the other poster dude's suggestion of just letting it through if you see an @ symbol. Wouldn't yours work with potentially too many weird character sets? probably language/runtime dependent

    Those character sets should work, the standards allow it. Your software should auto-punycode the domain part anyways.

  Famously won't work for n@ai, either with or without the trailing period to ensure global name resolution. The .ai is one of a rare few ccTLDs that have (or had) top-level MX and A records. https://mail.gnome.org/archives/evolution-list/2002-January/msg00466.html https://mail.gnome.org/archives/evolution-list/2002-January/...
