/etc/mailman/mm_cfg.py
added (at least for now):
# Set this Yes to activate VERP probe for disabling by bounce
# VERP_PROBES = No
VERP_PASSWORD_REMINDERS = Yes
VERP_PERSONALIZED_DELIVERIES = Yes
VERP_DELIVERY_INTERVAL = 1
VERP_CONFIRMATIONS = Yes
For better or worse with the installed Mailman version,
that's only globally configurable, not per-list.
Let's see if that helps nail some of the annoying bounces /
auto-responders where source isn't otherwise identifiable ...
Here's a typical example I get from sending to:
balug-announce@lists.balug.org
... but trimming headers ("only" removing those that offer no clue as to the
email address that "bounced" / auto-responded):
