       zmailstats - zmailer mail statistics


       zmailstats [options]


       A Perl script called zmailstats is supplied in the util directory. This
       has been hacked about quite a bit over time. It now gives quite  a  lot
       of  information  by  default,  but  there  are  options for suppressing
       various parts of it. Following any options, the arguments to the script
       are a list of files, which should be main log files.

       Zmailstats extracts information about the number and volume of messages
       received from or delivered to various hosts. The information is  sorted
       both  by  message  count  and  by  volume, and the top 50 hosts in each
       category are listed on the standard output. For messages delivered  and
       received locally, similar statistics are produced per user.

       The  output  also  includes  total counts and statistics about delivery
       errors, and histograms showing the  number  of  messages  received  and
       deliveries  made in each hour of the day. A delivery with more than one
       address in its counted as a single delivery by zmailstats.

       Though normally more deliveries than receipts are reported (as messages
       may  have multiple recipients), it is possible for zmailstats to report
       more messages received than delivered, even though the spool  is  empty
       at  the start and end of the period in question. If an incoming message
       contains no valid recipients, no deliveries are  recorded  for  it.  An
       error report is handled as an entirely separate message.

       Zmailstats  always  outputs a grand total summary giving the volume and
       number of messages received and deliveries  made,  and  the  number  of
       hosts  involved  in  each  case. It also outputs the number of messages
       that were delayed (that is,  not  completely  delivered  at  the  first
       attempt), and the number that had at least one address that failed.

       The  remainder  of  the output is in sections that can be independently
       disabled or modified by various options. It consists of  a  summary  of
       deliveries  by transport, histograms of messages received and delivered
       per time interval  (default  per  hour),  information  about  the  time
       messages  spent  on the queue, a list of relayed messages, lists of the
       top 50 sending hosts, local senders, destination hosts, and destination
       local  users by count and by volume, and a list of delivery errors that
       occurred. The options are as follows:


       -nt    Suppress the statistics about delivery by transport.

       -h<n>  This option controls the histograms  of  messages  received  and
              deliveries  per  time  interval. By default the time interval is
              one hour.  If -h0  is  given,  the  histograms  are  suppressed;
              otherwise  the  value  of  <n> gives the number of divisions per
              hour, so -h2 sets an interval of 30 minutes, and the default  is
              equivalent to -h1.

       -q0    Suppress information about times messages spend on the queue.

              This  option  sets an alternative list of time intervals for the
              queueing information. The values are separated by commas and are
              in  seconds,  but  can  involve  arithmetic  multipliers, so for
              example you can set 3*60 to specify 3 minutes. A setting such as


              causes  zmailstats to give counts of messages that stayed on the
              queue for less than one minute, less  than  five  minutes,  less
              than ten minutes, and over ten minutes.

       -nr    Suppress information about messages relayed through this host.

              Suppress  information  about  relayed  messages  that  match the
              pattern, which is matched against a string of the form

              H=<host> A=<address> => H=<host> A=<address>

              for example

     A=from@some.where => A=to@else.where

              The addresses are taken from the envelope, not the headers. This
              option allows you to screen out hosts whom you are happy to have
              using your host as a relay.

       -t<n>  Sets the ’top’ count to <n>. This controls the listings  of  the
              ’top  <n>’  hosts  and users by count and volume. The default is
              50, and setting 0 suppresses the output altogether.

       -tnl   Omit local information from the ’top’ listings.

       -ne    Suppress the list of delivery errors.
