configuration notes

This script is designed to be easy to use but still be flexible enough to accommodate a wide range of mailcow setups. The script pulls nearly all its configuration from the Mailcow configuration files themselves so it adapts to nearly all customizations you may have in your environment. The script accepts several optional parameters to override its defaults. In addition, it reads easy-to-edit external plain-text files for borg settings and extra files to backup so you don't have to weed through the script code to supply things like passwords.
