Interesting, missed the point of the . when initially looked at this,
Here's the regexp current in webkit
38 static const char emailPattern[] =
39 "[a-z0-9!#$%&'*+/=?^_`{|}~.-]+" // local part
40 "@"
41 "[a-z0-9-]+(\\.[a-z0-9-]+)+"; // domain part
(http://trac.webkit.org/browser/trunk/WebCore/html/ValidityState.cpp)
