   Options:
       -hnumber

           histograms. Valid values are:

           0, 1, 2, 3, 5, 10, 15, 20, 30 or 60.

       -ne Don't display error information.

       -nr Don't display relaying information.

       -nr/pattern/
           Don't display relaying information that matches.

       -nt Don't display transport information.

       -nt/pattern/

       -qlist
           List of times for queuing information single 0 item suppresses.

       -tnumber
           Display top <number> sources/destinations default is 50, 0
           suppresses top listing.

       -tnl

           Exim must have been configured to use the +delivery_time logging
           option for this option to work.

           list is an optional list of times. Eg -show_dt1,2,4,8 will show the
           number of messages with delivery times under 1 second, 2 seconds, 4
           seconds, 8 seconds, and over 8 seconds.

       -show_rtlist
           Show the receipt times for all the messages. The receipt time is
           defined as the Completed hh:mm:ss - queue_time_overall - the
           Receipt hh:mm:ss.  These figures will be skewed by pipelined
           messages so might not be that useful.

           Exim must have been configured to use the +queue_time_overall
           logging option for this option to work.

           list is an optional list of times. Eg -show_rt1,2,4,8 will show the
           number of messages with receipt times under 1 second, 2 seconds, 4
           seconds, 8 seconds, and over 8 seconds.

       -byhost
           Show results by sending host. This may be combined with -bydomain
           and/or -byemail and/or -byedomain. If none of these options are
           specified, then -byhost is assumed as a default.

       -bydomain
           Show results by sending domain.  May be combined with -byhost
           and/or -byemail and/or -byedomain.

       -byemail
           Show results by sender's email address.  May be combined with
           -byhost and/or -bydomain and/or -byedomain.

       -byemaildomain or -byedomain
           Show results by sender's email domain.  May be combined with
           -byhost and/or -bydomain and/or -byemail.

       -pattern Description /Pattern/
           Look for the specified pattern and count the number of lines in
           which it appears.  This option can be specified multiple times. Eg:

            -pattern 'Refused connections' '/refused connection/'

       -merge
           This option allows eximstats to merge old eximstat reports
           together. Eg:

            eximstats mainlog.sun > report.sun.txt
            eximstats mainlog.mon > report.mon.txt
            eximstats mainlog.tue > report.tue.txt
            eximstats mainlog.wed > report.web.txt
            eximstats mainlog.thu > report.thu.txt
            eximstats mainlog.fri > report.fri.txt

           o   The order of items in the top n lists may vary when the data
               volumes round to the same value.

       -charts
           Create graphical charts to be displayed in HTML output.  Only valid
           in combination with -html.

           This requires the following modules which can be obtained from
           http://www.cpan.org/modules/01modules.index.html

           GD
           GDTextUtil
           GDGraph

           To install these, download and unpack them, then use the normal
           perl installation procedure:

            perl Makefile.PL
            make
            make test
            make install

           On Debian GNU/Linux you can use "apt-get install libgd-perl
           libgd-text-perl libgd-graph-perl" instead.

       -chartdirI <dir>
           Create the charts in the directory <dir>

       -chartrelI <dir>
           Specify the relative directory for the "img src=" tags from where
           to include the charts

       -emptyok
           Specify that it's OK to not find any valid log lines. Without this
           we will output an error message if we don't find any.

       -d  Debug flag. This outputs the eval()'d parser onto STDOUT which
           makes it easier to trap errors in the eval section. Remember to add
           1 to the line numbers to allow for the title!

DESCRIPTION
       Eximstats parses exim mainlog and syslog files to output a statistical
       analysis of the messages processed. By default, a text analysis is
       generated, but you can request other output formats using flags. See
       the help (-help) to learn about how to create charts from the tables.

TO DO
       This program does not perfectly handle messages whose received and
       delivered log lines are in different files, which can happen when you
