Security Consideration

This image has not been extensively tested for security.

Only containers from docker network can use the smtp relay.

You shouldn't expose the port 25 of this container directly on the Internet.


  1. First start the smtp relay container

    docker run -d --name smtp-relay -e SMTP_HOSTNAME=smtp.domain.tld xadozuk/smtp-relay
  2. Link the smtp relay to another container

    docker run -d --link smtp-relay:smtp <image>
  3. Connect to the smtp relay with smtp:25 inside your container.

  4. Enjoy !
