The ASP.NET RegEx validator has some predefined validations. For internet
e-mail it has the following regex:

\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

Heres the one I use, I got it from
http://www.breakingpar.com/bkp/home.nsf/Doc?OpenNavigator&U=87256B280015193F87256C40004CC8C6

string regex = @"^(([^<>()[\]\\.,;:\s@\""]+(\.[^<>()[\]\\.,;:\s@\""]+)*)|(\"".+\""))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$";
