title: validate email address with Python
body: <p>I'm trying to validate emails using <a href="https://pypi.python.org/pypi/validate_email" rel="nofollow">validate_email 1.3 : Python Package Index</a>, like this:</p>
  
  <pre><code>from validate_email import validate_email
  is_valid = validate_email('example@example.com',check_mx=True)
  </code></pre>
  
  <p>How can I speed this up? My <code>for</code> loop isn't very effective with amount of emails I need to verify...</p>
