there is a mix of what all are used, its mostly the in-reply-to that is
supposed to be used, akait. References is also there, but introduced
much later ( was it down to a Microsoft feature that they insisted get
into the rfc ? ).
See what your mail.strict_threading and mail.thread_without_re are set
to; if you disable threading by subject, a very very large number of
emails will lose thread sanity on this list.
setting reply and changing subject does not change threads if your mail
client is already doing the right thing. My argument here is that not
all mail clients do, therefore sticking with subject line sanity would
help increase the number of threads that can stay together.
