If people are unaware, protection of email headers (for PGP) is
progressing at https://modernpgp.org/memoryhole/ (although it may be a
bit stalled.)
This looks like the usual approach of wrapping the message in an outer
message with all of the headers genericised. Ned Freed has said this has
severe patent problems. I don't know the details.
