There is, but it is somewhat sensitive to what sites call themselves,
which may account for this.  If your neighbors' news systems know your
site as "frobozz" but your software puts "frobozz.edu" in the Path line
of articles you receive, your neighbors will happily keep on sending
you articles that have already passed through your site once.  It is
fairly important that a site be known by one and only one name for news
purposes.
