netquick i have installed docker mailcow, everything is fine, but i want in same host second docker mailcow install but i have same bind address problems , how can i do this ?
pkernstock I really don’t understand the purpose about having multiple mailcow instances on the same host… however: It’s technically not possible to run multiple services on the same IP and port combination. You need to let each individual service listen on a specific IP to get this working - and that’s not supported out of the box.
