I believe the tracker is returned when you call send for a particular message, and that same tracker is then passed when the on_tracker_accept etc methods are called after the delivery is accepted etc. You would use the tracker itself to correlate to a particular sent message however you wish to.
That package you reference looks like 0.22.0, which is very old now. I know there are packages of newer releases published at https://launchpad.net/~qpid/+archive/ubuntu/released, something to consider.
