def delivered_to
  # Messages can be sent to multiple people AND if it was forwarded will have multiple
  # Delivered-To headers. What this bit of code does is take the
  # intersection of the "to" recipients and the "Delivered-To" recipients to find
  # out who the message was actually delivered to. There will almost never
  # be more than one recipient in that intersection, but if there is, we'll just 
  # return the first.
