Related to another thread (about email programs), another shortcoming of Claws Mail is that there's no way to see/edit *all* a reply's headers; otherwise, I would've adjusted this message's Message-id header to match that of the O.P.'s message and make this reply appear in the right place in the thread. I don't have the original message to reply to.
