There are a few possibilities. First is
bounce_unrecognized_goes_to_list_owner set to Yes for the list. If
not, and the bounce is not recognized as such, it will be silently
discarded.

Another possibility is the bounce is recognized, but because of
aliasing or forwarding or ? at the recipients end the address in the
bounce is not identically the same (except for case) as her subscribed
address. In this case the recognized bounce for a non-list-member is
silently discarded.

Yet another possibility is the DSN is a delay, not a failure so no
bounce is recorded.

If you really want to see the DSN, temporarily change the alias for
partyhats-bounces to go to you rather than to Mailman.
