@Edent @PlaneSailingGames That isn't end-to-end encryption, that is only transport layer encryption: the email still gets decrypted by every mail server it passes through, and still sits unencrypted (or at least, readily decryptable by the provider) in your mailbox.
End-to-end encryption means it gets encrypted by the sender and decrypted by the recipient, not by any of the hope in between.
