Hi there, I’m trying to set up mailcow to try it out. I am following these instructions for docker: https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_install/

I have a directory, I am root and I clone the repository. I run the generate_config script, and enter my domain mailcow.example.com, then I edit the config to change bindings as I already have a reverse proxy running (but for the sake of just getting it running I’m not using it quite yet):
HTTP_PORT=8090
HTTP_BIND=127.0.0.1
HTTPS_PORT=8443
HTTPS_BIND=127.0.0.1

With that being the only change I make, I start the container (as root as per instructions):
sudo docker-compose up -d

It starts up some containers then I get a log that looks like this:
sudo docker-compose up WARNING: The WATCHDOG_NOTIFY_EMAIL variable is not set. Defaulting to a blank string.
