If you use a VPN it can also mask it too. That’s how I used to get around it before moving to Google Fi.

I use both. I have a self hosted docker compose instance of mailcow, which alerts me when an update is available.

I also use protonmail as well.

Self hosting was a pain in the ass to get working, but I’ve had no issues with it once up. I tossed it behind a reverse proxy to keep it from directly touching the internet.

I use Comic Mono and love it. Code is 100% easier on the eyes and to read.
