I’m thinking about this every once in a while. What about using a custom domain and a relay service like FireFox Relay or Addy.io? That would give you the option to move your actual email around easily, even after you lose access to it.

This is why we need RISC-V.

Imho, without hardware support they won’t be able to keep up against the hackers. In the end it’s software and it’s running on hardware outside of the control of the server. There are millions of possible attacks to break/bypass this.
