Thanks for the reply, but no. I had to, indeed, remove the domain from $mydestination to not deliver locally, but it's still not working correctly.
Your map configuration lines may be wrong. I think the only thing you need is this as a destination: /^List@List\.TLD$/ mailman3: (no [127.0.0.1]:8024 after it) And your service runs as a socket, not on port 8024. Kai
