This image is a CentOS 6 container running postfix preconfigured for SMTP relay authentication. It runs as an open relay mail server inside the Docker Containers internal network, so it can be used by any container to send emails through the remote relay.
docker build -t eeacms/postfix .
The relay is set in the environment variable: `MTP_RELAY`.
Update the `.secrets` with your smtp authentication.
The hostname of the postfix server is set in: `MTP_HOST`.
Usage:
The `.secrets` file should be used as a runtime environment variables, and set the user and password required for SMTP authentication by the `MTP_RELAY`:
MTP_USER=user
MTP_PASS=password
Basic way to get one instance up and running:
docker run --rm -t -i --env-file=.secret --name=postfix eeacms/postfix
docker run --rm -t -i --env-file=.secret --name=postfix eeacms/postfix
From the application container, running on the same docker host, one can set the SMTP server to the postfix container address.
