This is very strange. What seems to be happening is the (un)subscription
notification is bouncing, causing a bounce notification to be sent to
the list owner, but a bounce notification should only be sent if the
original (bounced) message was to a list member, not the owner.

Also the bounce notification should also have an attached DSN with
details of why the (un)subscription notification bounced. What does that

Post the full raw bounce action notice with all headers and MIME parts
and I might be able to say more.

See Q2
