I have added some comments if you want to pursue this further.

Yes, but unrecognized bounces do happen from time to time for other
reasons such as full mailboxes and so forth. Mailman isn't perfect at
recognizing and parsing all bounce messages.

Item 2 would avoid the issue for unrecognized bounces, but it would be
better to find and fix the underlying problem if we can.

The bouncing address is the listname-owner address which appears to get
mapped by the bounce processor into an actual address from the list's
owner attribute.

We can't say exactly why the message was not accepted by Exim but there
should be messages in both the Exim logs and in Mailman's smtp-failure
log that can shed light on this. We'd like to see those messages.

I don't think this is the reason, because I thing the message is not
accepted from Mailman by Exim. If the above were the reason, I think
the bounce would occur later on Exim's attempt to deliver to Yahoo.
