I know this is not the question you asked but I noticed that your regex is not accepting any address like 'myemail@office21.company.com' or any address with a subdomain. You could replace it with something like :

/[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}/

which will reject less valid e-mail (although it is not perfect).

I also suggest you read this article on e-mail validation, it is pretty good and informative.
