I've got a magento site running on a new .club domain, but the site owner, cannot seem to use their *@*.club domain email in the admin panel. When you enter a .club in the Store Email Addresses section, you cannot save them as it error's with invalid email address.
What do I need to edit in js/prototype/validation.js to allow the new 4-6 character domain names, to be acceptable email addresses for the store?
