That algorithm uses the Subject:, In-reply-to: and References: headers. 
  A number of mail clients use this algorithm and it's being proposed as 
an extension of the IMAP protocol, so it must be pretty good :-)

Basically the idea is that you can deduce more about message threading 
by looking at the various message headers than just looking at the 
Subject header alone. Some mail clients do it well, some not so well.
