Rick Adams (rick@seismo.css.gov) posted a very nice fix to this
problem some time back.  Since it is small, I will post it again
(here).

First, create a file named "rnews.x" in your news library directory
containing:

exec /bin/cat $* > /usr/spool/news/rnews.$$

Next, you make your nightly news script do the following
(I believe that the "install" command is a BSD-specific command;
a combination of "cp", "chown" and "chmod" will replace it for
other sites):

#! /bin/sh

umask 002

# Prevent additions to history file while expire is running
/usr/bin/install -c -m 4755 -o news  /usr/lib/news/rnews.x /usr/bin/rnews

# actually expire the articles
#  if this was invoked manually, pass along the flags too 
cd /usr/lib/news
/usr/lib/news/expire -v2 $*

# get a fresh logfile
/bin/mv log olog
/bin/cp /dev/null log
/bin/chmod 666 log
/bin/cat olog >>log.mtd
/bin/rm -f ohistory.pag ohistory.dir ohistory olog

# turn rnews loose
/bin/rm -f /usr/bin/rnews
/bin/ln /usr/lib/news/inews /usr/bin/rnews
cd /usr/spool/news
for i in rnews.*
do
	/usr/bin/rnews <$i
	/bin/rm -f $i
done
