Did that.

Describe the bug
A clear and concise description of what the bug is.

Happily, docker-mailserver is running again. I have deactivated TLS to get things simple, can call domain:81 which redirects to login page.

Now did I create a user yet? I don't remember and try what I would have used -- no success.

So I call bin/production.sh run --rm web setup.sh and it works as expected.

But then I get an error message: Domain name: This value is already used.

And I keep getting this even if I use an address I certainly did not use before.

root@IONOS_2: /root/docker-mailserver # bin/production.sh run --rm web setup.sh

There were some errors. Please start over again.
2020/06/03 21:25:56 Command exited with error: exit status 1

Why? A search in source code delivered no results:

root@IONOS_2: /root/docker-mailserver # grep -rn './' -e "Domain name: This value is already used." | grep -v ':#' | grep -v ':wp_'

root@IONOS_2: /root/docker-mailserver # 

Even Google did not know about this error.

I went as far as # cat /opt/manager/bin/console but did not get any wiser. I thought about getting rid of the volumes to start fresh but then I knew they were fresh.

What to do now?

Additional context
Add any other context about the problem here.

Well, I stopped the services without removing the volumes, then started again. Now it worked.

Login worked as well. Sigh.
