Howto: Use Your Own TLS Certificates

1. Remove the ssl service from docker-compose.yml, by removing the entire block.
2. Uncomment the volume notations in the mta and mda blocks, delete the data-tls mounts:

    mta:
      image: jeboehm/mailserver-mta:latest
      ...
      volumes:
        - /home/user/certs/mail.example.com.crt:/media/tls/mailserver.crt:ro
        - /home/user/certs/mail.example.com.key:/media/tls/mailserver.key:ro
   
    mda:
      image: jeboehm/mailserver-mda:latest
      ...
      volumes:
        - data-mail:/var/vmail
        - /home/user/certs/mail.example.com.crt:/media/tls/mailserver.crt:ro
        - /home/user/certs/mail.example.com.key:/media/tls/mailserver.key:ro
   

3. Delete the data-tls volume from the volumes section by removing the entire block.
