title: Laravel - Validate email domain
body: <p>I want to validate domain when user enter invalid domain eg theemail@invaliddomainame.com</p>
  <pre><code>$createAccount_validator = Validator::make($request-&gt;all(), [
  
          'username'=&gt;'required|min:6',
          'email'=&gt;'required|email|unique:userTable)',
  
  ]);
  </code></pre>
  <p>Currently API of email validation is premium so I don't want to use.</p>
