Thanks for you contribution. However, it is way too strict.

It misses all the interesting characters that are allowed in the local
part, i.e.:

    ! $ & * - = ^ ` | ~ # % ' + / ? _ { }

RFC 5322 (4.3.1) says the local part is a dot-atom, 3.2.3 says a
dot-atom is a atext which includes alphanumeric plus the characters
mentioned above.

I'd be delighted to see an implementation that parses all corner cases,
i.e. foo/bar=baz example com or !foo%bar?baz*qux example com, correctly.
That might be a challenging Summer of Code assignment ;-)

Happy Hacking ;-)
