Hi Thomas, > I have been meaning to implement Autocrypt [1] in my nmh configuration
Thanks for the pointer. I've only read up to https://autocrypt.org/level1.html#the-autocrypt-header so far, but note Autocrypt: [email protected]; [prefer-encrypt=mutual;] keydata=BASE64 ... The addr attribute is mandatory, and contains the single recipient address this header is valid for. If this address differs from the one in the From header, the entire Autocrypt header MUST be treated as invalid. The Internet Message Format documents three types of originator fields: From, Sender, and Reply-To. Autocrypt is concerned only with the From field, and ignores the other originator fields. `Internet Message Format' is a link to RFC 5322, but that also has `3.6.6. Resent Fields' that includes the Resent-From: header that nmh sometimes uses. I'd expect to be able to encrypt an email I'm redistributing with dist(1), leaving the original From: alone, and appearing in the Resent-From: instead, but that doesn't seem possible with Autocrypt? -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
