I've run an XMPP server in various states of professionalism for around 20 years now. From mom's basement all the way to a colocated server with a similar setup that's described in the post.
The only caveat I have not been able to solve is hosting an xmpp server for a different domain, like it's possible with email.
A client connecting the account [email protected] will find the server it wants to connect to via SRV to be , e.g., xmpp14.example.COM and expect a TLS certificate for "example.ORG" which that server does not have (nor can/should easily get) - which makes sense in a lot of ways, but limits the ways one can offer hosting services.

If anyone has creative solutions I'm all ears.
