Encrypting the message content sounds sensible. But as far as I'm aware you can't encrypt the to/from fields.

As we've seen recently, this kind of metadata is often just as revealing as the content.

Encryption for email is probably giving you a false sense of security. If you care about privacy, email feels inappropriate to me.

So then the question is, what is the alternative? Honest question—I feel kind of helpless about it.
