Configuration file Template

[Smiley-k]

Hi, I'm trying to understand how all the functionality is configured, I figured out how to set up smtp, but I still can't figure out how to set up receiving mail, calendar, how to set up connecting to my SSO (I use Authelia), I need at least an example of the full configuration file, or I can't find it and it's somewhere-that is.

Thank you very much
