is the an possibility to set up Mailcow-Dockerized with IPv6?Any help ist appreciated.
Should be possible https://docs.docker.com/engine/userguide/networking/default_network/ipv6/
I've not the best exp with IPv6 and Docker but it should be possible. Change your docker-compose file and adjust the listen configs manually.
But why? Imho giving each Container a public-routeable IPv6 Addr is a bad thing
