Yes you are right, I am not really the exim4 or unix expert. But so far
the docker image exim4 works perfect. So thanks to all of you working on
this project.

Do you think we can build a docker image for exim4 together? For
docker-swarm such an image is a perfect solution to allow services so
send out mails via an gateway. And as I said, I am not really the
expert. But I did not found a better solution for docker so I tried to
help myself.
