icinga/nagios plugin to monitor the postfix mailqueue using the postqueue command.
based on: https://exchange.icinga.org/exchange/check_postfixmailqueue
this version mainly adds perfomance data to the plugin output.
check_postfixmailqueue -w -c [ -v ] [ -h ]
-w Queue size at which a warning is triggered"
-c Queue size at which a critical is triggered"
-v Verbose output (ignored for now)"
-h Show this page"
NOTE: Depending on your config, the nagios user will probably be needed to be added to the postfix group for this script to function correctly
