    [...]
  };

  outputs = {self, nixpkgs, ...}@inputs: {

    nixosConfigurations.tuxzentrale = inputs.nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      specialArgs.inputs = inputs;
      modules = [
        inputs.mail-quota-warning.nixosModule

        ({ pkgs, ... }:{

          nixpkgs.overlays = [
            inputs.mail-quota-warning.overlay
          ];

        })

        ./configuration.nix

      ];
    };
  };
}

Add this to your configuration.nix file

environment.etc."eintopf-radar-sync-secrets.yml".text = ''
EINTOPF_AUTHORIZATION_TOKEN=foobar23
'';

services.mail-quota-warning = {
  enable = true;
  settings = {
    CHECK_INTERVAL_DAYS = 7;
    QUOTA_WARNING_THRESHOLD_PERCENT = 80;    
  };
  secrets = [ /etc/mail-quota-warning-secrets.yml ];
};
