Supervisor and rsyslog may not be needed

[jaylinski]

Hi!

I stumbled upon this repository because of issue #45 (which helped me a lot) and noticed that you are still using supervisord and rsyslogd.

I'm also running postfix in an alpine docker-container and was able to get rid of both supervisord and rsyslogd:

• Since version 3.3.0 (February 21, 2018) it is possible to run Postfix in foreground mode via postfix start-fg, which eliminates the supervisord dependency.
• Since version 3.4.0 (February 27, 2019) it is possible to directly log to stdout, which eliminates the rsyslogd dependency:
  postconf -e "maillog_file=/dev/stdout".

Maybe you can simplify this image with this info.

(I read about this in detail here: https://xc2.wb1.xyz/post/how-to-run-a-postfix-mail-server-in-a-docker-container/)

@jaylinski On develop branch I have implemented this, there is juanluisbaptiste/postfix:1.1.0-develop.1 if you want to test it out before merging with pull request #59 .

Nice! I currently have no time to try this, but the change looks good. 👍
