Better delivery and avoids exposing your IP via emails, although it’s best to setup a some sort of tunnel to avoid having that problem altogether.
Is it possible to have a public-facing instance without exposing your IP? I am not sure I understand that part, and I am very interested in understanding how to achieve that.
Yes, you tunnel all your traffic through cloudflare.
Google “Cloudflare tunnel”.
Whatever people say about cloudflare, right now it’s a necessity if you manage a public facing server and don’t have the resources to avoid DDoS attacks.
For incoming http(s) connections you can hide behind Cloudflare, which also helps for caching pictures. For outgoing connections to other instances you could also hide behind an outgoing proxy, in my opinion that’s not really necessary, but I’m sure others would disagree on that.
