"memoryhole" refers to "protected headers", not just encrypted headers. That is, the headers can be protected both by cryptographic signature *and* by encryption. This is a subtlety, but probably worth getting right as we work on documentation and implementations. This is on my list of things to work on for notmuch, but i'd be happy if someone else beat me to it. clearly i've taken too long to get this done. fwiw, memory-hole messages do display successfully in all versions of notmuch i'm aware of, but they do so by rendering the "force-display" part. so notmuch currently uses the fallback arrangements as explicitly intended by the original memoryhole draft. as i see it, the steps are (in order): * handle encrypted subject correctly during message display time if the message is being decrypted. * handle encrypted subject specifically during message decryption at indexing time, storing it the correct subject field, instead of storing the "outside" subject. * suppress display of any "force-display" part during message display time. * handle any other cryptographically-protected headers during display and indexing. * generate protected headers when encrypting mail. i welcome help with any of these steps :) --dkg
