Hola Danther, he estao mirando el codigo y en validateEmail() yo quitaría lo de "validate country code" porque creo que se podría hacer directamente con la expresión regular.
En este sitio he visto también una expresión regular pero creo que es .net:
http://haacked.com/archive/2007/08/21/i-knew-how-to-validate-an-email-address-until-i.aspx
string pattern = @"^(?!\.)(""([^""\r\\]|\\[""\r\\])*""|"+ @"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)" + @"@[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$";
