Protected E-Mail Headers.
Encrypted or signed e-mail does not have cryptographic protection of headers; only the body of an e-mail message is encrypted or signed.
The Memory Hole project aims to fix this problem by stashing relevant headers within the body of the e-mail in a standardized way. Compatible mail user agents should be able to use this structure to display the cryptographically protected headers to the user, indicating their protection.
