mailcow: dockerized requires some ports to be open for incoming connections, so make sure that your firewall is not blocking these.
Make sure that no other application is interferring with mailcow’s configuration, such as another mail service
A correct DNS setup is crucial to every good mailserver setup, so please make sure you got at least the basics covered before you begin!
