Email validation is not always as simple as your regular expression. Have you looked at:

Validate email address in JavaScript?

A better option would be to use Verimail.js. It's a simple script that takes care of it for you. With Verimail.js you could just do:

var email = "cool@fabeook.cmo";
var verimail = new Comfirm.AlphaMail.Verimail();

verimail.verify(email, function(status, message, suggestion){
    if(status < 0){
        // Incorrect syntax!
    }else{
        // Syntax looks great!
    }
});

The above example will hit the line 'Incorrect syntax!' because of the invalid TLD 'cmo'. Besides this, it will also give a suggestion that you can return to your user, in this case, the suggestion variable will contain 'cool@facebook.com' since 'fabeook.cmo' looks a lot like 'facebook.com'.

Hope this helps!
