title: Deleting mail permanently using java Mail
body: <p>I have been using java mail to automate Gmail operations.
  One of the operation is to delete mail and I use following for it -</p>
  
  <pre><code>message.setFlag(Flags.Flag.DELETED, true);
  </code></pre>
  
  <p>but doing so only pushes my mails to spam folder.</p>
  
  <p>I am wondering if there is a straight way to delete mail permanently instead of deleting mail from "inbox" first and then searching mails in "spam " folder and deleting them.</p>
