I've hesitated to ever attempt this because every residential ISP I've had refuses to offer static IP addresses.
As well, deploying a server in a Google/Amazon/Microsoft datacenter which could be surreptitiously monitored defeats the theoretical privacy aspects of on-premises mail server hosting inside one's personal residence.
However, today, I looked into the newish movement of 'confidential computing' in the cloud (where data in motion - e.g., in memory - is encrypted and cannot be observed from the OS or hypervisor).
I openly wonder if one solution, then, is to build a secure VM that acts as a simple forwarding proxy to one's home server, gets assigned a static IP from a datacenter, and is deployed on one of these confidential computing instances, ensuring full E2E data privacy and data control?

Any guesses?
