#             strict, processes domain level aliases, more
#             subroutines, send reply from original to address
#
# 2004/11/09  David Osborn <ossdev at daocon.com>
#             Added syslog support          
#             Slightly better logging which includes messageid
#             Avoid infinite loops with domain aliases
#
# 2005-01-19  Troels Arvin <troels at arvin.dk>
#             PostgreSQL-version.
#             Normalized DB schema from one vacation table ("vacation")
#             to two ("vacation", "vacation_notification"). Uses
#             referential integrity CASCADE action to simplify cleanup
#             when a user is no longer on vacation.
#             Inserting variables into queries stricly by prepare()
#             to try to avoid SQL injection.
#             International characters are now handled well.
#
# 2005-01-21  Troels Arvin <troels at arvin.dk>
#             Uses the Email::Valid package to avoid sending notices
#             to obviously invalid addresses.
#
# 2007-08-15  David Goodwin <david at palepurple.co.uk>
#             Use the Perl Mail::Sendmail module for sending mail
#             Check for headers that start with blank lines (patch from forum)
#
# 2007-08-20  Martin Ambroz <amsys at trustica.cz>
#             Added initial Unicode support
#
# 2008-05-09  Fabio Bonelli <fabiobonelli at libero.it>
#             Properly handle failed queries to vacation_notification.
#             Fixed log reporting.
#
# 2008-07-29  Patch from Luxten to add repeat notification after timeout. See:
#             https://sourceforge.net/tracker/index.php?func=detail&aid=2031631&group_id=191583&atid=937966
#             
# 2008-08-01  Luigi Iotti <luigi at iotti dot biz>
#             Use envelope sender/recipient instead of using
#             From: and To: header fields;
#             Support to good vacation behavior as in
#             http://www.irbs.net/internet/postfix/0707/0954.html
#             (needs to be tested);
#
# 2008-08-04  David Goodwin <david at palepurple dot co dot uk>
#             Use Log4Perl
#             Added better testing (and -t option)
#
# 2009-06-29  Stevan Bajic <stevan@bajic.ch>
#             Add Mail::Sender for SMTP auth + more flexibility
#
# 2009-07-07  Stevan Bajic <stevan@bajic.ch>
#             Add better alias lookups
#             Check for more heades from Anti-Virus/Anti-Spam solutions
#
# Requirements - the following perl modules are required:
# DBD::Pg or DBD::mysql 
# Mail::Sender, Email::Valid MIME::Charset, Log::Log4perl, Log::Dispatch, MIME::EncWords and GetOpt::Std 
#
# You may install these via CPAN, or through your package tool.
# CPAN: 'perl -MCPAN -e shell', then 'install Module::Whatever'
#
# On Debian based systems : 
#   libmail-sender-perl
#   libdbd-pg-perl
#   libemail-valid-perl
#   libmime-perl
#   liblog-log4perl-perl
#   liblog-dispatch-perl
#   libgetopt-argvfile-perl
#   libmime-charset-perl (currently in testing, see instructions below)
#   libmime-encwords-perl (currently in testing, see instructions below)
#
# Note: When you use this module, you may start seeing error messages
# like "Cannot insert a duplicate key into unique index
# vacation_notification_pkey" in your system logs. This is expected
# behavior, and not an indication of trouble (see the "already_notified"
# subroutine for an explanation).
#
# You must also have the Email::Valid and MIME-tools perl-packages
# installed. They are available in some package collections, under the
# names 'perl-Email-Valid' and 'perl-MIME-tools', respectively.
# One such package collection (for Linux) is:
# http://dag.wieers.com/home-made/apt/packages.php
