thanks for the update on the current state of mailman3. The digest bug you linked seems to be related to 'summary digests' only. However, I also don't get any mails delivered, if I choose 'mime digests' as a delivery mode.
Also, I'm not quite sure about the precedence of settings: Which settings are taken if I have different ones in global settings, address settings, and subscription-based settings?
Thanks and warm regards
