      Indeed, but it is slower[1] (15.91s vs. 9.80s as per time(1) on a recent
      maillog), and seemingly inaccurate, e.g.:

      % ./postscreen_stats.py maillog
      === unique clients/total postscreen actions ===
      [ .. ]
      16215/48869 DNSBL
      12778/35372 HANGUP
      [ .. ]

      % grep ': DNSBL' maillog | wc -l

      % grep ': HANGUP' maillog | wc -l

      If you have any follow up questions, we can take this off-list given the
      OT nature of the discussion.

      [1] This may seem insignifcant, but makes an appreciable difference when
      creating reports across several log files.
