Subject: [PATCH] add support for message delivery failure notifying

This is similar to the support for message delivery receipts
themselves, so it's actually just as simple as checking for the
correct 'type', and the importing the two hacks that we already have
for message delivery receipts, namely those in b277759 and d49bf12 -
we probably want to move them into a common area eventually, but this
is fine for now, and definitely works in our tests just now.
