A reason for threading errors in Mail.app

[Dennis Brown]

Dan and Mac Mail.app users and anyone who replies to messages,

I have noticed that Mail.app seems to put seemingly unrelated threads  
into an existing thread at times.  I think I see a possible  
explanation for this.  In addition to the usual method of looking at  
the subject text, I think mail.app also fingerprints messages  
somehow, so it knows when a reply is to that message --even if the  
subject line is altered.  So if somebody starts a new thread by  
replying to a thread I started or replied to, just to get the header  
info, then replaces the body and subject lines to a new topic, my  
Mail.app assumes it is still related to the original message.  I just  
tested out this theory by replying to a thread I started, but I  
changed everything about the message except the To: line.  Sure  
enough the message came back threaded to the unrelated message I  
started it from.

A case of too smart for its own good!
