When we permanently failed to deliver to one or more recipients, send delivery status notifications back to the sender. To do this, we need to extend a couple of internal structures, to keep track of the original destinations (so we can include them in the message, for reference), and the hostname we're identifying ourselves as (this is arguable but we're going with it for now, may change later).
