   5 # Christoph Lameter, 21 May 1997
   6 # Modified by Philip Hazel, June 1997
   7 # Bug fix: June 1998 by Philip Hazel
   8 #   Message sizes not listed by -bp with K or M
   9 #   suffixes were getting divided by 10.
  10 # Bug fix: October 1998 by Philip Hazel
  11 #   Sorting wasn't working right with Perl 5.005
  12 #   Fix provided by John Horne
  13 # Bug fix: November 1998 by Philip Hazel
  14 #   Failing to recognize domain literals in recipient addresses
  15 #   Fix provided by Malcolm Ray
  16 # Bug fix: July 2002 by Philip Hazel
  17 #   Not handling time periods of more than 100 days
  18 #   Fix provided by Randy Banks
  19 # Added summary line: September 2002 by Philip Hazel
  20 #   Code provided by Joachim Wieland
  21 # June 2003 by Philip Hazel
  22 #   Initialize $size, $age, $id to avoid warnings when bad
  23 #   data is provided
  24 # Bug fix: July 2003 by Philip Hazel
  25 #   Incorrectly skipping the first lines of messages whose
  26 #   message ID ends in 'D'! Before Exim 4.14 this didn't
  27 #   matter because they never did. Looks like an original
  28 #   typo. Fix provided by Chris Liddiard.
  29 # November 2006 by Jori Hamalainen
  30 #   Added feature to separate frozen and bounced messages from queue
  31 #   Adedd feature to list queue per source - destination pair
  32 #   Changed regexps to compile once to very minor speed optimization
  33 #   Short circuit for empty lines
  34 #
  35 # Usage: mailq | exiqsumm [-a] [-b] [-c] [-f] [-s]
  36 #   Default sorting is by domain name
  37 #   -a sorts by age of oldest message
  38 #   -b enables bounce message separation
  39 #   -c sorts by count of message
  40 #   -f enables frozen message separation
  41 #   -s enables source destination separation
  42
  43 # Slightly modified sub from eximstats
