There is no such functionality in Rmail, so the only way is to code
it first.

You are talking about treating email as news group discussions.  I
don't need to go that far; if I did, I'd probably switch to Gnus.

All I want is to find the messages related to a certain subject.  I
don't care much to build a tree-like structure out of them, because
the body of the messages has that information, and that is normally
enough for my needs.

Well, I have yet to find such cases, then.

Anyway, we are repeating ourselves.  It is quite clear that you don't
see a problem in what the tracker does, while I do, because it
interferes with the way I'm used to read mail for many years.  I guess
we will have to agree to disagree on that.
