Hello,
I come from managing Linux servers on my own and having experience with server control panels like DirectAdmin, Plesk, cPanel and so on. At the moment I think about converting to cloudron because I have one or two applications that cause a maintenance nightmare, e. g. where maintaining them causes so much workload that it's not feasible anymore due to quick release cycles, complex update or upgrade processes and so on.
For now, I understand that Cloudron does take care of the OS and the specific apps it supports so I have no work with that. I also found out that I can use so-called add-ons to use e. g. one PostgreSQL instance for multiple apps to save hardware resources.
What I don't see: Is it possible to operate a standalone, open source, stable mailserver solution like mailcow, exim/postfix, etc.? I read that Cloudron has an own mailserver in the paid license but no information on what it relies on and I dislike to have mails in Cloudron's UI itself. I prefer to have an own email app to make sure I can have a dedicated email environment.
Does something like this exist? If not, what would be a solution here? Using e. g. plesk + cloudron doesn't sound like it's supported or a good idea.
Best Regards,
