1. The magic 50 strongly points at SMTP delivery, not local.
2. The owner-listname alias is a feature of the local(8) delivery agent,
which is almost certainly not used in this case.
3. The local delivery agent uses a large duplicate elimination table,
and alias expansion is generally handled internally without a second
transit through the queue.
So no, that is a not a good lead.
