That makes sense. That might explain why ZeroTier is sometimes unstable for me. It seems to create virtual MAC addresses, which may cause network connectivity issues. I think I might switch to Tailscale, hopefully it will be more stable

I think it contains a lot of information. Simple definitions always need a human touch

I've already installed WireGuard, ZeroTier, and OpenVPN. What's the difference between Tailscale and these other tools?

Disclosure: I build Keenrig, a self-hosted app platform, and I'm considering packaging Stalwart. For people running it: what should a one-click install get right (auto-DNS, cert handling, backups of the data dir) so it doesn't feel worse than a manual setup

I also want to set up a mail server, but when setting it up, I heard that it needs to be authenticated so the mail doesn't go to spam and can be used as a service

I've been using Contabo, and so far, the service has been quite stable and professional. Updates are handled automatically, and I haven't encountered any major issues DigitalOcean seems a bit slower and more expensive in comparison, especially when Contabo offers a VPS with 4 CPU and 8 GB of RAM for just 4.50 euro/month.

This is usefull, many thanks! Im building Keenrig, a self-shoting opensource app that gives users subdomains for their app, and your comment made me take another look at this. because some cookie issue . I'm moving user apps off my main domain (keenrig.com) onto a separate one - keenrig.app. the main reason is isolation: an app on a user subdomain shouldn't be able to set cookies for my console, or for other user'apps. many thanks
