Provide a Dockerfile

[mreiche]

Hi.

I'm using the Fork grafana/smtprelay as container, but their version is just outdated, which doesn't support accepting untrusted remote tls certs.

I would like to copy their Dockerfile and provide it here, to prevent even more forks.

What are your thinking about that? What are your thinking about publishing an official decke/smtprelay image?

Best,
Mike

I currently do not plan to provide any Docker images and support for it myself. Please see #54 , #50 and #85.
