title: Liferay No Folder Update Mail Notification on Document upload
body: <p>I'm subscribed to a document folder.</p>
  
  <p>I've setup mail configuration and I receive update emails after some document is edited (e.g. Description change).</p>
  
  <p>When someone add folders or media documents inside my subscribed folder, I don't get any email.</p>
  
  <p>Is this supposed to work as it is?
  Any suggestions?</p>
