Mail Receiver for Healthcheck

This is a simple docker container which acts as SMTP backend and forwards pings from mail to healthchecks.

I made this up, because the docker container I use for healthchecks does not include smtp, and I did not want do maintain this container on my own.

Usage:

Basically run the docker container with the following environment variables set:

• PING_URL: The base url for the ping to healthchecks in the format https://yourinstance.com/ping/ please do not remove the trailing slash.
• PING_ID: The ID to track the health of this script/container itself.
• PING_TIMEOUT: The time between pings for the script should be done.
• MAIL_DOMAIN: The domain name to accept messages for.
