python3 run_autoresponder.py
If you want to run the script multiple times with different configurations on each executions, you can achieve that by running
python3 run_autoresponder.py --config-path /the/path/to/your/config/file/autoresponder.config.ini
Usage as a cronjob
For production use you can configure it as a cronjob.
From the shell, run:

*/1 * * * * python3 /the/path/to/the/project/folder/run_autoresponder.py
This will run the script every minute.
