Postfix

An extension of bokysan/postfix⁠ which includes optional SSL configuration

Getting Started

This docker container utilizes the bokysan/postfix⁠ Docker container as a base. This container extends the bokysan/postfix container to allow SSL-based Postfix configuration when the certificates are supplied.

Mount the secrets in your Docker container to /mnt/certs. The container expects the following files to be present in order to continue running and setting up the TLS configuration:

• tls.crt
• tls.key
• ca.crt

Development

This container doesn't diverge much from its base image. I added a new script certinstaller.sh to push the TLS configuration into the postfix configuration.
