Hi, With notmuch built from very recent git (sha 3a45d29) it would seem that when forwarding an HTML only message as RFC822, once received, the message does not have any headers and notmuch-show merely displays 'Date: Thu, 01 Jan 1970 00:00:00 +0000'. I've stripped my .emacs back to a bare minimum configuration and the behaviour is the same. With a message (incidentally sent by MS Outlook) that contains the following parts: [ multipart/related ] [ text/html ] Once forwarded as RFC822 by notmuch and received, it is displayed by notmuch-show as: [ message/rfc822 ] Date: Thu, 01 Jan 1970 00:00:00 +0000 [ multipart/mixed ] [ multipart/related ] [ text/html ] While with a message that contains the following parts: [ multipart/mixed ] [ text/plain ] Once forwarded as RFC822 by notmuch and received, it is displayed by notmuch-show as: [ message/rfc822 ] From: xxxx Subject: xxxx To: xxxx Date: Fri, 15 Jul 2016 17:48:17 +0000 [ multipart/mixed ] [ text/plain ] So the headers are missing in the first case. I'm sure this is a regression. Can anybody verify this? Cheers, -- Matt
