I think all it takes is one person using a mailer that doesn't properly send "in reply to headers" to break the thread.
Usually it's the References header that is used to tie things together.
Actually, done right, it's both. If anybody wants to know how threading is done properly (Thunderbird has still deficiencies, AFAIR), jwz documented the Algorithm-To-Use(tm): http://www.jwz.org/doc/threading.html That document also supplies information about the relevant headers that goes beyond standards, with data to back it up. When I implemented my last MUA, I found that page invaluable. The approach presented there really works, all others have problems in some places.
