Thank you Mark. The problem was, that the bounce-process was dying as we had nearly 200.000 unprocessed bounce messages in database. After setting UPDATE bounceevent SET processed = 1;
the bounce-process keeps running and bounce.log is going wild and logs Member ... already scored a bounce on list list.domain.tld today.
I see now the bounce-queue is quickly decreasing.

Dear Users,
during one of our upgrades to 3.3.x we set verp_probes: yes according to upgrade notes[1].
However it looks like this disabled bounce handling completely.
Howto verify (MM 3.3.9):
Set verp_probes: yes verp_delivery_interval: 1 restart mailman3 create test-list add an undeliverable recipient to the list that is known to bounce. send 6 mails to list.
Bounce score is only incremented on the first bounce for that day.
see, that all the bounce-messages are received by mailman according to postfix log[2]
So they are delivered. At this point, having set
verp_probes: yeshas no effect on the processing. It only comes in to play when the threshhold is reached.check bounce.log - no entry. get bounce_score from API[3] - shows bounce_score 0.
This says bounces are not being processed. Is the bounces runner running? If it is there should be entries like
Member undeliverable-recipient@realdomain.tld on list v-test.lists.lists.tld, bounce score = 1.
and
Member undeliverable-recipient@realdomain.tld already scored a bounce on list v-test.lists.lists.tld today.
in bounce.log. and bounce score should be 1. This is independent of
verp_probes: yes.If the bounce runner is not running, stop and start Mailman core. You must stop and then start, not restart.
Also check mailman.log for a reason why bounces runner is not running.
If bounces runner is running, check mailman.log for possible errors relating to bounce processing.
