RFC2311 (SMIME) and RFC1847 (upon which PGP/MIME has been based) only
allow MIME headers to be protected by the encryption process. Was there
any discussion during the preparation of RFC1847 about the possibility
/ desirability / feasibility of allowing general RFC822 headers to
be included in the encrypted part of the message?
Its quite acceptable to generate your message as a message/rfc822 mime type
and encrypt the entire body.
