[MM3-users] How to connect mailman into existing postfix server

Hi to all,

I am trying to setup mailman3 with the Docker Image. Everythings works relative nicely but I am blocked by the Postfix integration part.

I have a small postfix server that is delivering mails to known domains and an alias map. The standard use case assumes that the external postfix is only routing mails to the mailman lmtp. If I do this all my old users are recected.

I am looking for an example(s) to integrate mailman into a Postfix configuration as an additional target for postfix.

Any hints

Regards

Hagen
