qsummary script

["Michael R. Gettes" <gettes@Princeton.EDU>]

The following script shows a summary of the zmailer queues.
It shows the hosts queued, number of msgs and recipients per host queue.
It identifies active hosts (a connection or resolution is in progress).
specifying "-d pattern" like "-d princeton" would show detailed info
(what you would see from mailq -s) on any host containing princeton.
You can also restrict your view without the -d option as well. You
need perl to run it, of course. Alter the $mailqcmd to reflect the path
to your mailq command for zmailer. Enjoy!

# The total line shows total number of hosts, msgs and recips
# The A found on some lines shows active connections
