ppizzo/postfix repository overview

⁠Postfix

Docker Postfix image configured to act as a relay host.

⁠Configuration

The image is provided with a default Postfix configuration file main.cf.template which is used to create the actual configuration file when the container starts. The values are read from the following enviroment variables:

• POSTFIX_DOMAIN
• POSTFIX_RELAY_HOST
• POSTFIX_RELAY_PORT
• POSTFIX_RELAY_USERNAME
• POSTFIX_RELAY_PASSWORD

⁠Running

With basic Docker knowledge it's pretty straightforward to build and run the image, after having adapted the provided files to suit your needs.

A default docker-compose-template.yml file has been provided for Swarm clusters for test purposes.

If running in production it's better to use a Kubernetes cluster with the enviroment variables stored as secrets.
