[Request] EmailRelay

Hi,

I’m proud to let you know that I’ve release an updated Docker image of
EmailRelay, with the latest Alpine and EmailRelay sources + multiple binaries available.

But I think that an official linuxserver.io image would be wonderful, isn’t it?

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 LibreElec - it works quite fine as an SMTP proxy!

All the details are on GitHub - nicozanf/EmailRelay: E-MailRelay application on a Docker container and the
images are on Docker Hub.
