title: Magento hostname validation errors
body: <p>When i tried to register with an email on magento store that I am developing I came across with errors that i havent seen before
   that says:</p>
  
  <pre><code>"Email" is not a valid hostname
  
  does not appear to be a valid local network name
  
  appears to be a DNS hostname but cannot match TLD against known list magento
  </code></pre>
  
  <p>When I did my research I foundout that these errors comes are caused by the Zend hostname validation.</p>
  
  <p>Is it possible to resolve these or there's no solution at all</p>
