> "zero knowledge" policies for e-mail I don't believe this is entirely possible. If Google were to encrypt all incoming email with your public key (so that only you could decrypt them) at the entry point (SMTP), it would still be possible to law enforcement/government to force Google to copy the incoming emails prior to the encryption step. Even if all incoming emails were encrypted prior to hitting Google's servers, the headers would still be visible (plus things like automated emails will probably never be encrypted).
