title: Strip signatures and replies from emails
body: <p>I'm currently working on a system that allows users to reply to notification emails that are sent out (<em>sigh</em>).</p>
  
  <p>I need to strip out the replies and signatures, so that I'm left with the actual content of the reply, without all the noise.</p>
  
  <p>Does anyone have any suggestions about the best way to do this?</p>
