You are wasting your time doing it that way.  Invest a little time in
learning the beginnings of RegExps, and you will soon profit.

As it does seem pretty difficult to get it just right i'm going to try
searching a few places and my result I will post here.

Might try...

Check whole email and accept if they have ¬

a-Z 0-1 * _ - @ .

Check whole email, Must have the below ¬

@ .

Thanks for your reply.

Achieved what I needed but in PHP rather than JavaScipt

<?php
// Receiving variables
@$email = addslashes($_PO ST['email']);

if (! ereg('^[*a-z\'0-9]+([._-][*a-z\'0-9]+)*@([a-z0-9]+([._-][a-
z0-9]+))+$', $email)){
include_once("e rror.inc");
die();
}

if(preg_match('/\*@(hotmail|rbs |barclays|lloyd stsb|hsbc|natwe st)\.(com|
co\.uk)$/i',$email)){
include_once("n ot_allowed.inc" );
die();
}
?>

But if anyone wants to help convert the above to JS... ?

You are wasting your time doing it that way. Invest the time in
learning RegExps first.

It's a good idea to read the newsgroup c.l.j and its FAQ. See below.
