      As do the stock 2.9.6 packages that ship with Wheezy, and the Squeeze
      backports. The documentation on postfix.org should be quite adequate in
      terms of explaining the basics;

        Am I correct in thinking that postscreen is not a separate daemon, but a
        process running under master?

        If I use the same dnsbls that I currently have in my smtpd_*_
        restrictions, in the postscreen_dnsbl_sites, and if so do I still need
        then in the sptpd....
