		       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
                          675 Mass Ave, Cambridge, MA 02139, USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

			    Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

  Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and
modification follow.
\f
		    GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

    c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)
\f
These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

    c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
\f
  4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

  5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

  7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
\f
  8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

  9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

  10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

			    NO WARRANTY

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

    Scott Bronson) This can be configured in conf.pl (Org Prefs)

  - Preferences are now cached instead of read in every page load.
  - Improved URL parser
  - Added ability to read HTML messages by default instead of plain text
    (Display Options)
  - Added authenticated SMTP server support (configure in conf.pl)
  - Rewrote attachment handling code in compose.php
  - If aliases are typed in To, Cc, or Bcc, they are automatically looked up
    in the addressbook and converted to the associated addresses.
  - Added collapseable folder listing (an option that can be turned on in
    Folder Options)
  - Added alternating row colors to improve interface (Display Options)

1. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP4
---------------------------------------------

  If your webserver does not already have PHP4 you must configure it
  to work with PHP4. SquirrelMail uses the standard suffix .php for
  all PHP4 files. This is a quick and dirty guide to installing PHP4
  to run as CGI under Apache. How you end up doing this is up to you
  (your mileage may vary).

  NOTE: The new plugin architecture required the use of some functions 
  which are not in all versions of PHP4. You will need at least 
  PHP4 beta2. If you need to upgrade please go ahead and install the
  latest release version of PHP4.

a. Obtaining and compiling PHP4

  Point your favorite webserver at http://www.php.net/version4/ and
  download the source. Untar (tar xvfz filename-you-downloaded.tgz)
  the source, cd into the directory and run configure. To make PHP4
  work with SquirrelMail a commandline like this should do:

   ./configure --enable-track-vars --enable-force-cgi-redirect --with-gettext

  If you have a database like MySQL you might want to add something
  like --with-mysql to get database functionality.

  If you're going to use LDAP in the addressbook, you must compile PHP4
  with --with-ldap (see the PHP4 docs for more information).

  Run make to build the binary file. This will generate a binary file
  called "php". Move this file into a CGI-directory.

  You might also want to read the INSTALL file in the PHP-distribution
  :-)

b. Changing php.ini

  PHP defaults to look for php.ini (PHP's configuration file) in
  /usr/local/lib.  However, for security reasons, it is suggested
  that the location of this file is changed to someplace else.  This
  can be done at configure time with the configuration directive
  --with-config-file-path=PATH.

  Edit the php.ini file and make sure session.use_cookies is 1.  Also 
  be sure to change the session.save_path to someplace that can only 
  be read and written to by the webserver.  session.save_path is the
  location that PHP's session data will be written to.

  SECURITY WARNING - If a user has access to write PHP scripts on your 
  system and knows the location where PHP stores session data, he 
  could get a listing of the sessions being used and then read a given 
  session's data with his own PHP script.  Caution should be used when 
  setting up permissions and locations of php.ini and the session data.

c. Setting up .php files to use PHP4

  You need to create a .htaccess file in you SquirrelMail directory
  that looks something like this:

    AddType application/php4script .php
    Action application/php4script /cgi-bin/php

  You could also add these lines to your Apache configuration file.

d. Running into trouble

  Setting up Apache with PHP4 can be a non-trivial task. Read the PHP4
  and Apache documentation carefully if you run into trouble. If you
  have an experienced system administrator around ask her/him to help
  you.

2. SETTING UP IMAP
------------------

  This is not covered here :-/

3. OBTAINING AND INSTALLING SQUIRRELMAIL
----------------------------------------

  SquirrelMail is still under development. Therefore you should always
  get the newest version around. Look at
  http://www.squirrelmail.org/index.php3?page=5 to see what it
  is. If you want to be bleeding edge you might want to consider using
  the latest CVS version (with the latest and most fashionable of
  bugs).

a. Download SquirrelMail

  Get SquirrelMail from the address above if you do not have it or are
  uncertain if you have the newest version. Untar (again tar xvfz
  filename.tgz) SquirrelMail in a directory that is readable for your
  webserver.

b. Setting up directories

  SquirrelMail uses two directories to store user configuration and
  attachments that are about to be sent. You might want to have these
  directories outside of your web tree.

  The data directory is used for storing user preferences, like
  signature, name and theme. When unpacking the sources this directory
  is created as data/ in your SquirrelMail directory. This directory
  must be writable by the webserver. If your webserver is running as
  the user "nobody" you can fix this by running:

    $ chown -R nobody data
    $ chgrp -R nobody data

  Keep in mind that with different installations, the web server could
  typically run as userid/groupid of nobody/nobody, nobody/nogroup, 
  apache/apache or www-data/www-data.  The best way to find out is to read 
  the web server's configuration file.

  There also needs to be a directory where attachments are stored
  before they are sent. Since personal mail is stored in this
  directory you might want to be a bit careful about how you set it
  up. It should be owned by another user than the webserver is running
  as (root might be a good choice) and the webserver should have write
  and execute permissions on the directory, but should not have read
  permissions. You could do this by running these commands (still
  granted that the webserver is running as nobody/nobody)

    $ cd /var/some/place
    $ mkdir SomeDirectory
    $ chgrp -R nobody SomeDirectory
    $ chmod 730 SomeDirectory

  If you trust all the users on you system not to read mail they are
  not supposed to read change the last line to chmod 777 SomeDirectory
  or simply use /tmp as you attachments directory. 
  
  If a user is aborting a mail but has uploaded some attachments to it 
  the files will be lying around in this directory forever if you do not 
  remove them.  To fix this, it is recommended to create a cron job that
  deletes everything in the attachment directory.  Something similar
  to the following will be good enough:

    $ cd /var/attach/directory
    $ rm -f *
    
  However, this will delete attachments that are currently in use by people
  sending email when the cron job runs.  You can either (1) make sure that
  the cron job runs at an obscure hour and hope that nobody gets upset, or
  (2) you can run a modified version of the commands above.  Check out the
  man pages for other commands such as 'find' or 'tmpreaper'.
  
  One sample script you could set up that would erase all attachments, but
  wouldn't erase preferences, address books, or the like (just in case your
  attachment directory is the same as your data directory) might look like 
  this:
   
    $ rm `find /var/attach/directory -atime +2 | grep -v "\." | grep -v _`
    
  Remember to be careful with whatever method you do use, and to test out
  the command before it potentially wipes out everyone's preferences.

c. Setting up SquirrelMail

  There are two ways to configure Squirrelmail.  In the config/ directory,
  there is a perl script called conf.pl that will aid you in the
  configuration process.  This is the recommended way of handling
  the config.

  You can also copy the config/config_default.php file to config/config.php
  and edit that manually.

4. RUNNING SQUIRRELMAIL
-----------------------

  Point your browser at the URL at which SquirrelMail is installed.  A
  possible example of this is: 
     http://www.yourdomain.com/squirrelmail
     
  It should be pretty stright forward to use. Some more documentation
  might show up one day or another.


5. RUSSIAN CHARSETS
-------------------

http://www.squirrelmail.org

Introduction:
-------------
SquirrelMail is a standards-based webmail package written in PHP4. It
includes built-in pure PHP support for the IMAP and SMTP protocols, and all
pages render in pure HTML 4.0 (with no Javascript) for maximum compatibility
across browsers. It has very few requirements and is very easy to configure
and install. SquirrelMail has a all the functionality you would want from an
email client, including strong MIME support, address books, and folder
manipulation.  

Why did you guys create SquirrelMail?  The need arose in our organization
for the access of email and address books from anywhere in the world.
Obviously a web interface is ideal for this, given that the user has access
to the Internet.  After reviewing several open source projects, we realized
that we were going to need to do some fairly major customizations to get
things to be a nice fit for our needs.  So the decision was made to create
our own for some of these reasons, and for fun (we really like PHP4).  We
decided to open source the project to contribute to the community that has
contributed so much to us.  Since then, it has grown much bigger than we
ever imagined, and we have an awesome development team who are actively
working on the project.

We would love to hear from you!  The nature of open source projects make it
hard to know who all is using your product.  It is always nice when we get
emails from people just telling us that they're using SquirrelMail.  If you
have a few minutes, please send us an email to let us know!  You can send it
to our mailing list:  squirrelmail-list@sourceforge.net

You can also go to the page below and fill out a small form to get listed
with the list of people already using SquirrelMail (free advertising).

Contact:
--------
It is pretty easy to get in contact with the developers if you need help or
if you find bugs that need to be reported.  The best way to contact us would
be through our mailing list which is actively monitored.  Just send an email
to:

============================

If you are upgrading from versions 0.3 or higher of SquirrelMail, you can
use this guide to make the transition a bit smoother.  If you have been
using a previous version (0.1 or 0.2), it is suggested that you just start
from scratch and configure your settings as if it was your first install.

NOTE: The new plugin architecture required the use of some functions which
are not in all versions of PHP4. You will need at least PHP4 beta2. If you
need to upgrade please go ahead and install the latest release version of
PHP4.


1.  Backup old install
======================

Make a backup of your current SquirrelMail directory.  If you use "cp", be
sure to use the "-Rp" options.  -R means recursive, and -p will save the
permissions in the directory.

In this example, we assume that your httpd document directory is 
/home/httpd/html, that your SquirrelMail install is located at
/home/httpd/html/squirrelmail-0.4, and that your new SM version is 0.5.
Substitute version numbers and names as required.

  $ cd /home/httpd/html
  $ cp -Rp squirrelmail-0.4 squirrelmail-0.4.bak


2.  Unarchive new SquirrelMail
==============================
Make sure that you are in your httpd document directory (/home/httpd/html)
and then unarchive the SquirrelMail archive (whatever the filename is): 

  $ tar -zxvf squirrelmail-0.5.tar.gz


3.  Copy important files from old install
=========================================
The important files to copy are:
  A.  Preferences
  B.  Config details
  C.  Plugins
  D.  Themes (if you've edited or added any of them)
  
A.  Preferences

First, copy your preference data over to the new directory.  Usually this is
ok, but if you are upgrading from to 1.0.5 or later from anything less than
1.0.5, we strongly suggest you let your users reset their preferences.
There were important security upgrades in 1.0.5 regarding preference files.
  
  $ cp squirrelmail-0.4.bak/data/* squirrelmail-0.5/data
  
B.  Config details

If at all possible, start the configuration process from scratch.  It is 
much less prone to missing configuration options than copying your old
configuration.  Ideally, you should just run conf.pl to reconfigure
SquirrelMail.  If you decide to copy your old config.php over, we strongly
recommend that you run conf.pl to make sure things are correct and then save
the config file.

  $ cp squirrelmail-0.4.bak/config/config.php squirrelmail-0.5/config

C.  Copy plugins

Like SquirrelMail, plugins are fequently updated for improvements, as well
as to make them compatible with new SquirrelMail releases.  It is suggested
that you download a new plugins archive at the same time you download your
SquirrelMail install, and that you install your plugins fresh (it's easy,
don't panic!).

If you prefer to just copy your old plugins over (if it's the same version
or if you are lazy), you may do so.  If you notice irregularities with the
plugins under the new SquirrelMail, try installing new versions of the
plugins.

  $ cp -Rp squirrelmail-0.4.bak/plugins/* squirrelmail-0.5/plugins
  
D.  Copy themes

If you've created or modified themes, you should copy just those to the new
SquirrelMail themes direcory.  To just copy them all over to the new
SquirrelMail installation, you can run one command.

  $ cp squirrelmail-0.4.bak/themes/* squirrelmail-0.5/themes/

(While you are at it, you should send them to us!  We might add them to the
themes in the standard install!)


4.  Change permissions
======================
The web server must have write permission to the data directory.  In this
example, we assume that user "nobody" and group "nobody" are the web server
as is often the case with Apache.

  $ cd squirrelmail-0.5
  $ chown -R nobody.nobody data
  
See INSTALL for alternate userid/groupid pairs.  Additionally, if "chown
user.group" doesn't work, you can use "chown user" and "chgrp group"
instead.  See the man pages for these commands for more information.


5.  Run conf.pl
===============
Run config/conf.pl to see the new configuration options available with the
new version, as well as to verify that all of your old options are set
properly.


6.  DONE!
=========
That should be all!  The most important part is copying your users'
preference files back into the new data directory.  This will insure that
your users will have their old preferences.  Remember to do so with caution,
