Automated messags are still forwarded to the list admin although list bounce/drop notification disabled
You can disable notifications to list admins on bounces/drops: https://0xacab.org/schleuder/schleuder/blob/master/etc/list-defaults.yml#L91
# Send a notice to the list-admins whenever an email is bounced or dropped?
But this only has an effect within the filter runner itself, but is not respected when receiving automated messages:
=> Either we should also check there whether bounce notification is enabled and respect it or if the option seems not appropriate, we should add another setting, as list admins can easily be spammed through lots of automated messages.
