Before Exim 4.14 this didn't # matter because they never did. Looks like an original # typo. Fix provided by Chris Liddiard. # November 2006 by Jori Hamalainen # Added feature to separate frozen and bounced messages from queue # Added feature to list queue per source - destination pair # Changed regexps to compile once to very minor speed optimization # Short circuit for empty lines # # Usage: mailq | exiqsumm [-a] [-b] [-c] [-f] [-s] # Default sorting is by domain name # -a sorts by age of oldest message # -b enables bounce message separation # -c sorts by count of message # -f enables frozen message separation # -s enables source destination separation # Slightly modified sub from eximstats use warnings; BEGIN { pop @INC if $INC[-1] eq '.' }; use File::Basename; if (@ARGV && $ARGV[0] eq '--version') { print basename($0) .
