This poses a really interesting question. Another solution would be to use already existing remailers, and doubling the encryption together with the TO: email in the inline plaintext. The question is how to properly do a dual encryption.
My proposed solution is the following: Plaintext message (encrypted for recipient, with unencrypted portion dictating the recipient through inline text) -> Encrypted Message (encrypted again to remailer's PGP, including inline portion) -> Remailer (decrypted intended layer. Message is sent to recipient dictated in the inline text) -> Recipient's Email Server / Provider (cannot be read by provider) -> Recipient Mailbox On Sun, Jun 30, 2013 at 8:52 AM, <alice-...@safe-mail.net> wrote: > everyone is tooting about pgp these. pgp encryption doesnt solve the > problem of tla surveillance. pgp encryption does not touch metadata > (recipent, sender). > > how to secure mail communication? > > i was thinking about pointing the mx record of the tld to a mail server > that is shared with other individuals. the server is configured to drop > incoming non-tls smtp connection from other mail server.
