I am using mailcow dockerized like given, only changing things in the mailcow.conf file.
I can’t connect via SMTP, HTTPS, or anything from any other container over my the public ip of my server. I can connect to another nginx from inside containers.
I tried SNAT_TO_SOURCE=my_public_ipv4_of_my_server
It didn’t help, I can access it from any other server or from the host, but not from inside other docker containers on the same host. I am using docker-compose for all other containers.
Hope somebody can help me, how to fix this.
