Thank you Abhilash,
probably it's hard to tell, but somehow the container started with a different IP now. Do you have any clew, how this can happen? The network part is as follows:
networks:
mailman:
ipv4_address: 172.22.0.4-> but it has 192.168.176.6
Thank you in advance.

There are a bunch of $myxxxx variables in Postfix, I think $myhosts might be the right one.
It should be under $mynetworks as per documentation:
https://asynchronous.in/docker-mailman/#postfix
Also, official postfix docs says the same:
