It is the In-Reply-To field. For this message the field is:
In-Reply-To: <427FF716.1020907@fredonia.edu>

The value of this field is supposed to be a globally unique id generated by
your mail reader. If a mail reader groups messages only by subject then
there is no way to tell who responded to whom (and thus can't display the
messages in a threaded view), the In-Reply-To field gets around this
problem.

Thanks for your interest! :)

Take care, Matthew.
