xtremxpert/docker-postgrey repository overview

⁠Postgrey Docker image

This Docker image runs Postgrey⁠ f

⁠Running

docker run -d -p 10023:10023 xtremxpert/docker-postgrey

Now Postgrey is listening on port 10023 for Postfix access policy connections. It should be added to Postfix's main.cf like this:

smtp_recipient_restrictions =
  ...
  check_policy_service inet:postgreyip:10023

Note: Postgrey probably shouldn't be exposed externally on your host. So instead of exposing the port, use the container network IP or create a Docker network for connecting to the daemon.
