+
+# Perl script to generate statistics from one or more Exim log files.
+
+# Usage: eximstats [<options>] <log file> <log file> ...
+
+# 1996-05-21: Ignore lines not starting with valid date/time, just in case
+#               these get into a log file.
+# 1996-11-19: Add the -h option to control the size of the histogram,
+#               and optionally turn it off.
+#             Use some Perl 5 things; it should be everywhere by now.
+#             Add the Perl -w option and rewrite so no warnings are given.
+#             Add the -t option to control the length of the "top" listing.
+#             Add the -ne, -nt options to turn off errors and transport
+#               information.
+#             Add information about length of time on queue, and -q<list> to
+#               control the intervals and turn it off.
+#             Add count and percentage of delayed messages to the Received
+#               line.
+#             Show total number of errors.
+#             Add count and percentage of messages with errors to Received
+#               line.
+#             Add information about relaying and -nr to suppress it.
+# 1997-02-03  Merged in some of the things Nigel Metheringham had done:
+#               Re-worded headings
+#               Added received histogram as well as delivered
+#               Added local senders' league table
+#               Added local recipients' league table
+# 1997-03-10  Fixed typo "destinationss"
+#             Allow for intermediate address between final and original
+#               when testing for relaying
+#             Give better message when no input
+# 1997-04-24  Fixed bug in layout of error listing that was depending on
+#               text length (output line got repeated).
+# 1997-05-06  Bug in option decoding when only one option.
+#             Overflow bug when handling very large volumes.
+# 1997-10-28  Updated to handle revised log format that might show
+#               HELO name as well as host name before IP number
+# 1998-01-26  Bugs in the function for calculating the number of seconds
+#               since 1970 from a log date
+# 1998-02-02  Delivery to :blackhole: doesn't have a T= entry in the log
+#               line; cope with this, thereby avoiding undefined problems
+#             Very short log line gave substring error
+# 1998-02-03  A routed delivery to a local transport may not have <> in the
+#               log line; terminate the address at white space, not <
+# 1998-09-07  If first line of input was a => line, $thissize was undefined;
+#               ensure it is zero.
+# 1998-12-21  Adding of $thissize from => line should have been adding $size.
+#             Oops. Should have looked more closely when fixing the previous
+#               bug!
+# 1999-11-12  Increased the field widths for printed integers; numbers are
+#               bigger than originally envisaged.
+# 2001-03-21  Converted seconds() routine to use Time::Local, fixing a bug
+#               whereby seconds($timestamp) - id_seconds($id) gave an
+#               incorrect result.
+#             Added POD documentation.
+#             Moved usage instructions into help() subroutine.
+#             Added 'use strict' and declared all global variables.
+#             Added '-html' flag and resultant code.
+#             Added '-cache' flag and resultant code.
+#             Added add_volume() routine and converted all volume variables
+#               to use it, fixing the overflow problems for individual hosts
+#               on large sites.
+#             Converted all volume output to GB/MB/KB as appropriate.
+#             Don't store local user stats if -nfl is specified.
+#             Modifications done by: Steve Campbell (<steve@computurn.com>)
+# 2001-04-02  Added the -t_remote_users flag. Steve Campbell.
+# 2001-10-15  Added the -domain flag. Steve Campbell.
+# 2001-10-16  Accept files on STDIN or on the command line. Steve Campbell.
+# 2001-10-21  Removed -domain flag and added -bydomain, -byhost, and -byemail.
+#             We now generate our main parsing subroutine as an eval statement
+#             which improves performance dramatically when not all the results
+#             are required. We also cache the last timestamp to time conversion.
+#
+#             NOTE: 'Top 50 destinations by (message count|volume)' lines are
+#             now 'Top N (host|email|domain) destinations by (message count|volume)'
+#             where N is the topcount. Steve Campbell.
+#
+# 2001-10-30  V1.16 Joachim Wieland.
+#            Fixed minor bugs in add_volume() when taking over this version
+#               for use in Exim 4: -w gave uninitialized value warnings in
+#               two situations: for the first addition to a counter, and if
+#               there were never any gigabytes, thereby leaving the $gigs
+#               value unset.
+#             Initialized $last_timestamp to stop a -w uninitialized warning.
+#             Minor layout tweak for grand totals (nitpicking).
+#             Put the IP addresses for relaying stats in [] and separated by
+#               a space from the domain name.
+#             Removed the IPv4-specific address test when picking out addresses
+#               for relaying. Anything inside [] is OK.
+#
+# 2002-07-02  Philip Hazel
+#             Fixed "uninitialized variable" message that occurred for relay
+#               messages that arrived from H=[1.2.3.4] hosts (no name shown).
+#               This bug didn't affect the output.
+#
+# 2002-04-15  V1.17 Joachim Wieland.
+#             Added -charts, -chartdir. -chartrel options which use
+#             GD::Graph modules to create graphical charts of the statistics.
+#
+# 2002-04-15  V1.18 Steve Campbell.
+#             Added a check for $domain to to stop a -w uninitialized warning.
+#             Added -byemaildomain option.
+#             Only print HTML header links to included tables!
+#
+# 2002-08-02  V1.19 Steve Campbell.
+#             Changed the debug mode to dump the parser onto STDERR rather
+#             than STDOUT. Documented the -d flag into the help().
+#             Rejoined the divergent 2002-04-15 and 2002-07-02 releases.
+#
+# 2002-08-21  V1.20 Steve Campbell.
+#             Added the '-merge' option to allow merging of previous reports.
+#             Fixed a missing semicolon when doing -bydomain.
+#             Make volume charts plot the data gigs and bytes rather than just bytes.
+#             Only process log lines with $flag =~ /<=|=>|->|==|\*\*|Co/
+#             Converted Emaildomain to Edomain - the column header was too wide!
+#             This changes the text output slightly. You can revert to the old
+#             column widths by changing $COLUMN_WIDTHS to 7;
+#
+# 2002-09-04  V1.21 Andreas J Mueller
+#             Local deliveries domain now defaults to 'localdomain'.
+#             Don't match F=<From> when looking for the user.
+#
+# 2002-09-05  V1.22 Steve Campbell
+#             Fixed a perl 5.005 incompatibility problem ('our' variables).
+#
+# 2002-09-11  V1.23 Steve Campbell
+#             Stopped -charts option from throwing errors on null data.
+#             Don't print out 'Errors encountered' unless there are any.
+
+# 2002-10-21  V1.23a Philip Hazel - patch from Tony Finch put in until
+#               Steve's eximstats catches up.
+#             Handle log files that include the timezone after the timestamp.
+#             Switch to assuming that log timestamps are in local time, with
+#               an option for UTC timestamps, as in Exim itself.
+#
+# 2003-02-05  V1.24 Steve Campbell
+#             Added in Sergey Sholokh's code to convert '<' and '>' characters
+#             in HTML output. Also added code to convert them back with -merge.
+#             Fixed timestamp offsets to convert to seconds rather than minutes.
+#             Updated -merge to work with output files using timezones.
+#             Added caching to speed up the calculation of timezone offsets.
+#
+# 2003-02-07  V1.25 Steve Campbell
+#             Optimised the usage of mktime() in the seconds subroutine.
+#             Removed the now redundant '-cache' option.
+#             html2txt() now explicitly matches HTML tags.
+#             Implemented a new sorting algorithm - the top_n_sort() routine.
+#             Added Danny Carroll's '-nvr' flag and code.
+#
+# 2003-03-13  V1.26 Steve Campbell
+#             Implemented HTML compliance changes recommended by Bernard Massot.
+#             Bug fix to allow top_n_sort() to handle null keys.
+#             Convert all domains and edomains to lowercase.
+#             Remove preceding dots from domains.
+#
+# 2003-03-13  V1.27 Steve Campbell
+#             Replaced border attributes with 'border=1', as recommended by
+#             Bernard Massot.
+#
+# 2003-06-03  V1.28 John Newman
+#             Added in the ability to skip over the parsing and evaluation of
+#             specific transports as passed to eximstats via the new "-nt/.../"
+#             command line argument.  This new switch allows the viewing of
+#             not more accurate statistics but more applicable statistics when
+#             special transports are in use (ie; SpamAssassin).  We need to be
+#             able to ignore transports such as this otherwise the resulting
+#             local deliveries are significantly skewed (doubled)...
+#
+# 2003-11-06  V1.29 Steve Campbell
+#             Added the '-pattern "Description" "/pattern/"' option.
+#
+# 2004-02-17  V1.30 Steve Campbell
+#             Added warnings if required GD::Graph modules are not available or
+#             insufficient -chart* options are specified.
+#
+# 2004-02-20  V1.31 Andrea Balzi
+#             Only show the Local Sender/Destination links if the tables exist.
+#
+# 2004-07-05  V1.32 Steve Campbell
+#             Fix '-merge -h0' divide by zero error.
+#
+# 2004-07-15  V1.33 Steve Campbell
+#             Documentation update - I've converted the subroutine
+#             documentation from POD to comments.
+#
+# 2004-12-10  V1.34 Steve Campbell
+#             Eximstats can now parse syslog lines as well as mainlog lines.
+#
+# 2004-12-20  V1.35 Wouter Verhelst
+#             Pie charts by volume were actually generated by count. Fixed.
+#
+# 2005-02-07  V1.36 Gregor Herrmann / Steve Campbell
+#             Added average sizes to HTML Top tables.
+#
+# 2005-04-26  V1.37 Frank Heydlauf
+#             Added -xls and the ability to specify output files.
+#
+# 2005-04-29  V1.38 Steve Campbell
+#             Use FileHandles for outputting results.
+#             Allow any combination of xls, txt, and html output.
+#             Fixed display of large numbers with -nvr option
+#             Fixed merging of reports with empty tables.
+#
+# 2005-05-27  V1.39 Steve Campbell
+#             Added the -include_original_destination flag
+#             Removed tabs and trailing whitespace.
+#
+# 2005-06-03  V1.40 Steve Campbell
+#             Whilst parsing the mainlog(s), store information about
+#             the messages in a hash of arrays rather than using
+#             individual hashes. This is a bit cleaner and results in
+#             dramatic memory savings, albeit at a slight CPU cost.
+#
+# 2005-06-15  V1.41 Steve Campbell
+#             Added the -show_rt<list> flag.
+#             Added the -show_dt<list> flag.
+#
+# 2005-06-24  V1.42 Steve Campbell
+#             Added Histograms for user specified patterns.
+#
+# 2005-06-30  V1.43 Steve Campbell
+#             Bug fix for V1.42 with -h0 specified. Spotted by Chris Lear.
+#
+# 2005-07-26  V1.44 Steve Campbell
+#             Use a glob alias rather than an array ref in the generated
+#             parser. This improves both readability and performance.
+#
+# 2005-09-30  V1.45 Marco Gaiarin / Steve Campbell
+#             Collect SpamAssassin and rejection statistics.
+#             Don't display local sender or destination tables unless
+#             there is data to show.
+#             Added average volumes into the top table text output.
+#
+# 2006-02-07  V1.46 Steve Campbell
+#             Collect data on the number of addresses (recipients)
+#             as well as the number of messages.
+#
+# 2006-05-05  V1.47 Steve Campbell
+#             Added 'Message too big' to the list of mail rejection
+#             reasons (thanks to Marco Gaiarin).
+#
+# 2006-06-05  V1.48 Steve Campbell
+#             Mainlog lines which have GMT offsets and are too short to
+#             have a flag are now skipped.
+#
+# 2006-11-10  V1.49 Alain Williams
+#             Added the -emptyok flag.
+#
+# 2006-11-16  V1.50 Steve Campbell
+#             Fixes for obtaining the IP address from reject messages.
+#
+# 2006-11-27  V1.51 Steve Campbell
+#             Another update for obtaining the IP address from reject messages.
+#
+# 2006-11-27  V1.52 Steve Campbell
+#             Tally any reject message containing SpamAssassin.
+#
+# 2007-01-31  V1.53 Philip Hazel
+#             Allow for [pid] after date in log lines
+#
+# 2007-02-14  V1.54 Daniel Tiefnig
+#             Improved the '($parent) =' pattern match.
+#
+# 2007-03-19  V1.55 Steve Campbell
+#             Differentiate between permanent and temporary rejects.
+#
+# 2007-03-29  V1.56 Jez Hancock
+#             Fixed some broken HTML links and added missing column headers.
+#
+# 2007-03-30  V1.57 Steve Campbell
+#             Fixed Grand Total Summary Domains, Edomains, and Email columns
+#             for Rejects, Temp Rejects, Ham, and Spam rows.
+#
+# 2007-04-11  V1.58 Steve Campbell
+#             Fix to get <> and blackhole to show in edomain tables.
+#
+# 2007-09-20  V1.59 Steve Campbell
+#             Added the -bylocaldomain option
+#
+# 2007-09-20  V1.60 Heiko Schlittermann
+#             Fix for misinterpreted log lines

+=head1 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 (B<-help>) to learn
+about how to create charts from the tables.
+
+=head1 AUTHOR
+
+There is a website at https://www.exim.org - this contains details of the
+mailing list exim-users@exim.org.
+
+=head1 TO DO
+
+This program does not perfectly handle messages whose received
+and delivered log lines are in different files, which can happen
+when you have multiple mail servers and a message cannot be
+immediately delivered. Fixing this could be tricky...
+
+Merging of xls files is not (yet) possible. Be free to implement :)
