You trust the person, you get mail from and vice versa. There is no need to
trust the path. The path for the message is not important. Important is
that the content is not readable (compromised).

Another example - you know Enigma, perhaps. Everybody was listening, but no
one could understand. And it worked so good until the cipher was broken.
