#3081: Allow customisation of headers stripped by mutt_prepare_template() I mail out a git patch series by sending it to a mailbox, moving the messages into my postponed folder, and then recovering them to edit and send.
git-format-patch generates a thread by setting Message-ID on the first message and References & In-Reply-To on the subsequent message. Unfortunately, mutt strips Message-ID when retrieving postponed messages, so the thread ends up broken. Please change mutt_prepare_template() so that the set of stripped headers can be customised. -- Ticket URL: <http://dev.mutt.org/trac/ticket/3081>
