I didn't notice at first either, but he hid a "C library" constraint in the Subject.
I can't recommend a library, but I *can* tell you that email addresses aren't regular, so a regular expression is wrong.
Jeffrey Friedl's book "Mastering Regular Expressions" (O'Reilly) has an RFC 822 compliant regular expression in it that is meant to be very robust.
