      Good point. dnsblog will be silent ONLY when list.dnswl.org replies
      that the IP address is not listed (and perhaps when you send more
      queries than your dnswl.org subscription allows).

      Also the logging above is incomplete. You left out the CONNECT
      logging from postscreen (and perhaps more).

      For the complete postscreen/tlsproxy log:

      grep '\[209.85.219.51\]:41193' the-maillog-file

      for the dnsblog log

      grep 'Aug 26 21:21.*dnsblog.*209.85.219.51'
