title: What's the easiest/cleanest way to get the MessageID of a sent email?
body: <p>I want to save the MessageID of a sent email, so I can later use it in a References: header to facilitate threading.</p>
  
  <p>I see in root/django/trunk/django/core/mail.py (line ~55) where the MessageID is created.</p>
  
  <p>I'm trying to think of the best way to collect this value, other than just copy/pasting into a new backend module and returning it. Maybe that is the best way?</p>
