Hello,
I'm proud to let you know that I've release an updated Docker image of EmailRelay that runs really fine on Rpi3 and LibreELEC.
I've developed it mainly because I have an old appliance that can only use plain SMTP over port 25/TCP, which usage has recently been denied by my ISP. So, I've packed a Docker container of EmailRelay for my Raspberry Pi3 running as an SMTP proxy!
Details are on https://github.com/nicozanf/EmailRelay and images are on https://hub.docker.com/repository/docker/nicozanf/emailrelay
