title: jQuery Validation Email Validation Issues
body: <p>I am trying to troubleshoot and fix why my email validation is not properly working. It is suppose to detect an invalid email: where it had too many ...(dots), to still except European address (test@tom.uk.tk) as well as test@aol.com. But as of right now its excepting more that one dot, if you don't finish typing as long as it has the @ as long as you don't add the (.) dot. Will someone please help me with where I am going wrong?</p>
  
  <pre><code>&lt;script&gt;
       $("#form").validate({
      rules: {
          firstname_1: {
              required: true
          },
          email_1: {
              required: true,
              email: true
          },
          // Same for other fields
      },
      messages: {
          firstname_1: "This field is required.",
          email_1&gt;: "Please enter valid email address.",
          // Repeat for other fields
      }
  });
  function isValidEmail(email_1)
  {
      return /^[a-z0-9]+([-._][a-z0-9]+)*@([a-z0-9]+(-[a-z0-9]+)*\.)+[a-z]{2,4}$/.test(email_1)
          &amp;&amp; /^(?=.{1,64}@.{4,64}$)(?=.{6,100}$).*/.test(email_1);
  }
  &lt;/script&gt;
