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