Hallo,

I've installed iRedMail on a new Ubuntu 18.04 machine. I'm not very experienced with Nginx and therefore quickly encountered problems (with some other projects I wanted to host in the same server) and would like to switch back to Apache I know better. I don't want to run Nginx as a reverse proxy but want to have a clean system with just one webserver.

I've stopped nginx (service nginx stop) but nginx seems not to be installed via the package system ("apt remove nginx" reports that nginx is not installed). How do I have to remove nginx which was installed by iRedMail so that I can install apache?

Thanks in advance!
