This is pretty minimal..

The init script for nntp2mail runs:

  /usr/local/bin/tcpserver -H -l${HOSTNAME} -R -v -c 50 -u 60001 -g 60001 \
                           0 2119 /news/bin/nntp2mail 2>&1 | \
                           /var/qmail/bin/splogger nntp2mail 3 &

dnewsfeeds entry:

  label news-to-mail
    alias INTERNET
    addgroup foo.bar
    groupref EVERYONE
    maxconnect 2
  end

dnntpspool.ctl:

  news-to-mail         localhost                200        p2119

nntp2mail.cf:

  $NNTPtoMailGroups{'foo.bar'} = 'foo-bar-list@example.com';

And for the mailpost script, just put the following in the .forward (or
in our case, .qmail) file, to post to foo.bar:

  |/news/bin/mailpost foo.bar
