Strange new Encrypted email service, Bmail

I was very interested in the idea of using “SGX enclave” for e-mail sending. I have no idea how much I trust this specific provider, but I always saw this as a very weak link of the encrypted e-mail: If I delegate e-mail sending to Proton or Tuta, they could hypothetically intercept it under judicial order. Yet, If I host my own e-mail at home, I’d get deliverability issues. So at least great point for them to trying to address this.
