Where did this message come from? The message-id is not generated by
Postfix (different format), and yet you're reporting 127.0.0.1 as
the source. So where did this message originate? This message bounced,
with the non-delivery queued as:
AED108DFA2: sender non-delivery notification: A0E418DFA4

All you show for that is above. Below is some other message that also
bounces:

You also show fragementary logs for this bounce.

They are not "the same". Is there a mail loop somewhere? Are the
bounces delivered? Do they elicit new responses? The logs posted are
far from complete. They don't even consistently show the message-ids.
See my "collate" program:

I don't see how you reached that conclusion.

Nothing is "resent", new messages are showing up, bouncing and ...
(you don't show what happens with the bounces).
