title: Django queryset: Exclude list of emails using endswith
body: <p>I'm running metrics on user data and want exclude users that have bogus emails like '@example.com' or '@test.com'.</p>
  
  <p>I tried</p>
  
  <pre><code>emails_to_exclude = ['@example.com', '@test.com', '@mailinator.com' ....]
  Users.objects.exclude(email__endswith__in=emails_to_exclude)
  </code></pre>
  
  <p>Unfortunately this doesn't work. Looks like <code>endswith</code> and <code>in</code> don't play nice with each other. Any ideas?</p>
