Currently, filtermail always listens on localhost and assumes that postfix is always on localhost. This can be different in some setups, e.g. when filtermail and postfix are in separate docker containers (sharing the same docker network).
This PR adds configurable listen IP and postfix host via
LISTEN_IPandPOSTFIX_HOSTenv vars.Postfix host is resolved with
ToSocketAddrsso we can use an internal docker container host (e.g. service name when run in a docker compose) instead of finding out its IP address.I'm absolutely okay with maintaining a soft-fork for my "chatmail in docker" project (work in progress), but i thought it could be useful for the upstream as well. Feel free to provide any suggestions regarding the code.
