Can you please check if a yahoo.com email is involved? (they may trigger
these "bounce storms")

Comment (by vrautenbach):

I check now, there weren’t any yahoo emails. It was quite a range from
usgs to gmails. Let me know if I can give any more information.

Thank you the assistance.

I don't think I really solved the problem.
But a testing message from me has arrived to the mailing list

https://lists.osgeo.org/pipermail/announce/2020-December/000522.html

Up to now I have not received bounced messages.
Maybe only administrators receive the bouncing messages.
@vrautenbach Please report

I think it is only the administrators that receive the bounce emails. But
the mass unsubscribe and bounce emails (over 50) happend when I posted an
email to the list.

Should I add the emails removed during the bounce storm and post a new
email to the list to test if it happens again?

Comment (by neteler):

To check the current bounce states, you may

- activate in the mailman list settings that you (list admin) want to be
notified by email
- check on the server:
{{{
root@osgeo6:~# cat /var/log/mailman/bounce
}}}

Hint: To reset all bounce levels for all lists and members, run

{{{
root@osgeo6:~# withlist -a -r reset_bounce -- ## reset all mailman
bounce levels
}}}

Comment (by vrautenbach):

Good day All

This was recently again an issue. We had over 120 emails that bounced.
This occurred on 29 April. Is there anything from a user side that we can
do?

I checked now all these subscribers with bounced emails in this round is
still subscribed, but if I check some of the previous bounced mails (from
6 months ago), those subscribes are not listed as members of the mailing
list anymore, did the system remove them?

Regards
Victoria

We need to check once more if our list server complies with the
continuously changing email requirements/security measures.

I am afraid yes, see also my comment here:

Comment (by robe):

Since we've upgraded the server, which upgrades postfix, I'm hoping that
fixed whatever this issues is. Is this still happening?
