There is a recent thread on this beginning at

Yes, it would eliminate delivering those "unrecognized" delayed
notifications to the list owner, but it would also eliminate
delivering all other unrecognized bounces, some of which may be SPAM
or even desired messages sent to the list-bounces address and some of
which may be real bounces in a non-standard format which should be
seen. If this is a concern, you can set VERP_DELIVERY_INTERVAL to some
non-zero value in mm_cfg.py so every nth post is VERP'd and "real"
bounces will eventually be detected.
