On a related note, what about communicating with people who press reply
on an existing message, change the subject and start a new mail
thread. Most mail clients will still insert the In-Reply-To header,
which in this case is just wrong.

Ofcourse, it's their fault, but one can't educate the entire world. Is
there anything like mutt has, to break a thread at the current message?
