Docker verbose option

[soullivaneuh]

Here is a PoC as suggested on #100 (comment).

I just added verbose options but we can add more.

But I agree that having a maildev.json configuration file (#93) would be easier. With that, we will just have to link our config file to the docker container.

Another possibility: Let user set a OPTS env var that will be added to the default (web and smtp options should not be changed on docker due to exposed ports).

What do you think?

For this PR, I do think my feelings are still the same as this comment, but your point about using an OPTS or similar environment variable for additional args could be a cool point to meet halfway! I wonder, could we use an environment variable in the CMD itself and skip the entrypoint.sh?

ENV OPTS=""
CMD ["sh", "-c", "bin/maildev --web 80 --smtp 25", "$OPTS"]

Hi @djfarrelly, sorry for the delay.

I think your method is less reliable about option description, but we could do that.

Do you want me to update this PR accordingly to your demand?
