title: jquery validate, adding a new rule to check email host
body: <p>I'm trying to create a rule that checks is the email host is Hotmail so I can show a message asking to check their spam folder (most of my messages go to that folder when people use Hotmail). </p>
  
  <p>Here's what I've done so far: </p>
  
  <pre><code>       jQuery.validator.addMethod("isHotmail", function(value, element) {
             var email = $("#email").val();
             var emailHost = email.split('@')[1].split('.')[0];
             if(emailHost=='hotmail'){return true}
  }, "* you are using Hotmail, please check your spam folder");
  </code></pre>
  
  <p>And</p>
  
  <pre><code> rules: {
           email: {
             required:true, email: true, isHotmail : true
           }
  .
  .
  </code></pre>
  
  <p>This is not working, nothing happens if I enter a Hotmail email address,  and I suspect that it is because of the return statement. </p>
  
  <p>Can anyone please give me a hand with this rule? </p>
  
  <p>Thanks a lot</p>
