This is another side effect... yes. > I'd assume the first id in in-reply-to is used for the > thread-view and I'd assume mutt uses the first tagged mail first > in in-reply-to, but it's all an assumption and I haven't verified > it. I was thinking the same, *exactly* the same, but i don't know whether it's a good assumption... If you check the in-reply-to header, i see Erik as the last one, but still my multi-answer appears under his message in the threaded view. Also you say the first tagged mail, but in which sorting mode? In my case i tagged the three messages, and the sorting was reverse-date, and the quoting (how mutt automatically sourced the messages when answering) was not done accordingly. Maybe it's done on the base of the thread hierarchy, sice i can notice the order being the one in the 'threads' sort mode, from top to bottom (and recursive into children). Thank you all for having fun together :)
