i'm running a mailman-3.3.8 instance, and would like to reset the bounce-score for a (number of) user(s). i searched the internet and this list's archives, but haven't found anything useful so far.

due to a misconfiguration of our universities reverse DNS lookup, the bounce score of some users has rocketed in the last days - some users have already been unsubscribed because of that.

could anybody please share how i can reset the bounce score?

First of all, there are 3 categories of affected list members - those who are already unsubscribed, those who are still members but have delivery disabled by bounce, and those with delivery enabled but with bounce score > 0.

For those that have been unsubscribed, you just have to re-subscribe them.

For those that have delivery enabled but a non-zero bounce score, you may not need to do anything because they are presumably not currently bouncing so eventually the old bounce info will become stale and be ignored, but to guard against spurious bounces that may result in disabling, e.g.from an over aggressive user's spam filter, you can add verp_probes: yes to the [mta] section of mailman.cfg. The effect of this is when a members bounce score reaches threshold the score is reset and a special probe message is sent and delivery is disabled only if the probe bounces. See https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/model/docs/...

That leaves those with delivery disabled by bounce. Assuming you want to enable delivery for all members of all lists with delivery disabled by bounce, the following mailman shell interaction will do it.

$ bin/mailman shell
Welcome to the GNU Mailman shell

...         if member.delivery_status == DeliveryStatus.by_bounces:
...             member.preferences.delivery_status = DeliveryStatus.enabled
...

Watch out for a possible wrapped line above.
