- Attempt re-delivery by re-routing the message within the DR network

Messages that can't be delivered are released with a modified outcome.
To expand on this, look at the description of
https://issues.apache.org/jira/browse/DISPATCH-366.
If a delivery can't be routed (no destination), it is returned to the
sender with RELEASED disposition. If the delivery _may_ have been
delivered but has not been settled when an outgoing link is dropped, it
is returned to the sender with MODIFIED/delivery-failed disposition.
