          Issue Type: Improvement
            Reporter: Andrew Banks


Can the client and server store QoS=0 messages after a client using CleanSession=0 has disconnected
or must these messages be discarded. If they must be discarded then a temporary network outage will unnecessarily cause Qos=0 messages to lost.
