on GrapheneOS it is labeled auto reboot and it specifically says "automatically reboot device if it hasn't been unlocked in xxx hours" with a default of 18.

Caddy is the answer. Makes running a reverse proxy with certs totally straight forward.

Right you said that above and that is what resulted in my larger response. Reiterating without any more information doesn't really change your position in a tangible way. I appreciate that is your stance and many others' stance. I think we need to encourage the opposite to change the landscape of the internet.

We, selfhosters and sysadmins alike, need to change our tune around the position of "do not self host email." It only serves to keep email in the grip of big tech. Yes it is difficult and someone without any experience shouldn't start there but it is definitely manageable and not nearly as hard as it is made out to be.

There are multiple email "distributions" nowadays making the software stack set up and maintenance effectively an exercise in running a regular Linux distro upgrade. Mailinabox and mailcow to name two off the top of my head.

The DNS records are relatively straightforward to set up and validate with these mail distros, they basically tell you what to put and provide ways of validating you did what they said you should. There are also many ways to test that you set them up properly by having a service validate them via email you send to the testing service, e.g. mail-tester.com and dmarctester.com, finally DMARC has a report function builtin so you can get regular delivery reports that come directly from the servers that are choosing what to do with your email giving you a clear signal when there are problems.

You don't have to jump into hard mode around a clean IP either you can offload that for a nominal fee to an email service provider if you don't want to try your luck, e.g. MXroute.com has a one time fee for multiple domains.

Yes email is convulted and confusing at times and scary to host given how essential it is but I'd encourage anyone with the time and desire to do it.

Is the system Linux? If so, then yes you can. Rsync it on to the newly created device get the uiid and fix up the fstab and boot loader configs and you are back in business.

That's correct and a good way to test it out.

"invisible cryptography" I sure hope this isn't an empty promise. The number one gripe I have with matrix/element is the absolutely horrendous crypto dance they make you do.

Ampache, good web interface and subsonic client support.

What telegram book groups would you recommend?

Can you share the German podcasts you enjoy?

Munin is a tried and true solution. It installs on the server creates graphs and makes it easy to see a stair step graph to problems like out of memory.

I'd also highly recommend installing atop and having it collect stats every 1 to 2 minutes. You can go to a crashed server and step through what was running in a "top" like interfsce. I install atop on any server as a means for post incident diagnosis.
