Here's the relevant section from the documentation:
The service uses a tiered configuration system, each option takes precendence over the ones above it:
- The configuration file
- Environment variables starting with MAILROOM_
- Command line parameters
The config file defaults to `config.toml`
For example, to configure the log level:
For the configuration file, you create a `config.toml` file, and in it you place: 'log_level = "INFO"'
For the environment variable, you can set it with `export MAILROOM_LOG_LEVEL=INFO`
And for the command line parameter, `./mailroom --log-level INFO`
