@athanasia The main problem is that I don't front mbox.blue with my Edge infra that I front the rest of my infra with. So mbox.blue is kind of independent if that makes sense. It has nothing in front of it to protect anything. So I would just put a simple Caddy PoW at it's reverse proxy and call it a day if that works for you? -- I think I'll make this per-box/per-user configurable too?
