Thanks for pointing this out!

No, it is not a limitation -- Mail simply uses the only possible way 
threading can be done with emails: It is the purpose of the 
In-reply-to: header to provide information on how threads are 

If Mail only used the Subject: to find out which messages belong to one 
thread, there were other problems: Quite often the subject is changed 
willingly or unwillingly, and Mail would end up with messages belonging 
together separated into many threads.
(Perhaps such a mechanism would work in this list with almost anybody 
using Mac clients which seem to behave very standards-conform, but 
experiences from other lists with many Windows users show that 
oragnizing threads by subject does not have any chance to work here...)

A real limitation of Mail.app is that it cannot draw a tree of 
messages, i.e. it cannot show which messages are direct replies to 
others. But I am hoping for Tiger here...
