Postmasters at sites running USENET news may want to take a look at list mail
addressed to their site. Many ARPANET mailing lists are relayed into
the USENET news system, and users at USENET news sites should not need
to receive individual copies in addition to the USENET news copy.
We can help reduce much of this extra traffic by identifying the USENET
news group name of mailing lists in the INTEREST-GROUPS file(s) so
users will know where in USENET news to find there favorite mailing
list.
