Having an internal only mail server for notifications is an interesting idea. I've been using ntfy and Matrix to achieve something like that, but not all services support those notification methods. I'll keep that in mind!
If I started this setup later I might have also used pangolin, which also provides a nice management interface on top of WireGuard https://github.com/fosrl/pangolin
But it's a totally valid option, just not one that fit with my preferences
On my NixOS laptop I you can setup services I'm interested in trying, but just run them locally. So I don't setup things like SSL (you can, it sometimes just makes getting a new SSL cert for that same domain take some time). I just update my /etc/hosts to the local IP and can give that a go
For trying out the more complicated setup parts, like SSL, Tailscale, etc, I created a NixOS VM that I setup the same way I wanted for my "production" use case. Once I have the config file the way I wanted, it's as simple as moving it to my non test VM (baring previous mentioned SSL issues). And I only tested one part at a time, adding them together as I went
But also, one of the great things about NixOS is it's really easy to incrementally try things and rollback. Once I got the skeleton of the setup working, I've mostly done my testing on my "production" server without issue
But also if you're setup is working for you, I think that's great! It sounds like you have a good system in place
But I found the more services I used with Docker, the more time it took to update. I didn't want to just update to latest, I wanted to update to specific version, for better rollback. That meant manually checking and updating every single service, bringing each file down, and then back up. It's not entirely unmanageable, but it became enough friction I wasn't updating things consistently. And yes, I could have automated some of that, but never got around to it
NixOS, in addition to the things I mention in the post, is just a two step process to update everything (`nix flake update` and `nixos-rebuild`). That makes updating my OS and every package/service super easy. And provides built in rollback if it fails. Plus I can configure things like my firewall and other security things in NixOS with the same config I do everything else
Also, Nix packages/services provides a lot of the "containerization" benefits. It's reproducible. It doesn't have dependency problems (see this for morehttps://nixos.org/guides/how-nix-works/). And most services use separate users with distinct permissions, giving pretty good security.
It's not that Docker can't do those things. It's that Nix does those things in a way that work really well with how I think
