I use a front end script to do that.
e.g.

$ cat /usr/bin/lfetchnews
#!/bin/sh

res=`ls /var/spool/news/out.going/* 2>/dev/null |wc -l`

if [ $res != 0 ]
then
 echo "$res messages à poster ******"
 nom='<jom1NOSPAM\@voonoo.net>\r'
 echo "L'auteur est: $nom" 
 perl -00 -e "s/^From: .*\r/From: $nom/m" -p -i
/var/spool/news/out.going/*;
 echo $?
fi

 echo "Lancer fetchnews [o/n] [o] ?"
 read answer
 if test "$answer" != "" && test "$answer" != "O"; then exit; fi

echo "** fetchnews **"
exec /opt/sbin/fetchnews "$@"
