Docker container for mail_to_misp - email in your threat intelligence
Create a volume for configuration to mount on to /config will be helpful for setting up the config file of mail_to-misp. This will contain your settings for sending the email to misp as an event. Fake-smtpd doesn't need a configuration file, as the container handles anything that could be required. Exposing the container on a port other than 25 may require additional configuration.
The container must be run in interactive mode, or fake smtpd will fail to run. This is not a bug in the docker container, but a feature of how the code works.
