+1. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP
+--------------------------------------------
+
+ If your webserver does not already have PHP you must configure it
+ to work with PHP. You need at least PHP v4.1.0. SquirrelMail uses
+ the standard suffix .php for all PHP files.
+
+ You can find PHP at http://www.php.net. See the documentation that
+ comes with PHP for instructions how to set it up.
+
+ The PHP IMAP extension is NOT necessary at all (but won't harm)!
+ Below is a list of optional PHP extensions:
+
+ --with-ldap
+ Required for LDAP addressbooks
+
+ --with-pear and --with-mysql
+ For MySQL storage of preferences or addressbooks. You will need PHP
+ compiled with --with-pgsql option, if you want to use PostgreSQL instead
+ of MySQL. You will need PHP with appropriate database extension, if you
+ want to use any other database.
+
+ --with-openssl
+ Required for encrypted IMAP or SMTP connections (TLS)
+
+ --with-mcrypt
+ Can be used by SquirrelSpell plugin for encryption of personal
+ dictionaries
+
+ --with-iconv or --with-recode
+ Can be used by Eastern charset decoding functions
+
+ --enable-mbstring
+ Required for Japanese translation. Optional for translations that
+ use non-ISO-8859-1 charset
+
+ It is highly advised to NOT turn on register_globals, as this can lead
+ to security holes. If you must use register_globals for some applications,
+ turn it on locally for only those directories, or turn it off for the
+ SquirrelMail folder.
+ If you want your users to attach files to their mails, make sure
+ File Uploads in php.ini is set to On.
+
+
+2. SETTING UP IMAP
+------------------
+
+ This depends a lot on the server your choose. See the documentation
+ that comes with your server.
+
+ If you're concerned about people accessing it directly, you can
+ limit access to only the IP of the webserver.
+
+
+3. OBTAINING AND INSTALLING SQUIRRELMAIL
+----------------------------------------
+
+ SquirrelMail is constantly being improved. Therefore you should always
+ get the newest version around. Look at http://www.squirrelmail.org
+ 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 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. You need to create this directory yourself.
+ Recommended location is under /var, for example:
+ /var/local/squirrelmail/data
+ This directory must be writable by the webserver. If your webserver is
+ running as the user "nobody" and group "nobody" you can fix this by
+ running:
+
+ $ chown -R nobody:nobody /path/to/your/datadir
+
+ 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, you can 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/local/squirrelmail/attach
+ $ 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/local/squirrelmail/attach -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 three 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.
+
+ There's also a plugin called 'administrator' for the webinterface but you'll
+ have to be able to at least log in to SquirrelMail first.
+
+ You can also copy the config/config_default.php file to config/config.php
+ and edit that manually.
+
+ After you've created a configuration, you can use your webbrowser to
+ browse to http://your-squirrelmail-location/src/configtest.php.
+ This will perform some basic checks on your config to make sure
+ everything works like it should.
+
+
+4. RUNNING SQUIRRELMAIL
+-----------------------
+
+ Point your browser at the URL at which SquirrelMail is installed. A
+ possible example of this is:
+ http://www.example.com/squirrelmail
+
+ It should be pretty straight forward to use. Some more documentation
+ might show up one day or another.
+
+
+5. RUSSIAN CHARSETS
+-------------------
+
+ For information on how to make SquirrelMail work with Russian
+ Apache, see the russian_apache.txt in the doc/ subdirectory.
+
+
+6. TRANSLATIONS
+---------------
+
+ In order to use translated versions of SquirrelMail, you need
+ to download and install locale packages that contain translations
+ that you want to use with SquirrelMail.
+
+ Locale packages can be downloaded from SquirrelMail SourceForge
+ project page.
+
+ http://sourceforge.net/project/showfiles.php?group_id=311&package_id=110388
+
+ Each translation contains an install script that copies the required files
+ into their appropriate locations. If you can't run that script, you can
+ extract the contents of a translation package into your SquirrelMail
+ directory.
+
+ NOTE No.1: *-src.tar.gz, *-src.tar.bz2 and *-src.zip archives do not contain
+ compiled translation files. You will need to run the "compilelocales" script
+ in order to get all gettext binary translations.
+
+ NOTE No.2: You might need to restart your webserver before using translations.
+ If you can't do that, install your translations _before_ you use SquirrelMail.
+
+
+7. PLUGINS
+----------
+
+ The SquirrelMail package includes some standard plugins. These plugins can be
+ enabled in the SquirrelMail configuration script.
+
+ Included plugins can use additional configuration files:
+ * change_password
+ configuration file is required. Without it plugin defaults to invalid
+ backend. See plugins/change_password/README
+ * filters, fortune, mail_fetch, newmail, translate
+ configuration files are optional. See README files in plugin directories.
+ * squirrelspell
+ configuration is stored in plugins/squirrelspell/sqspell_config.php
+ Default configuration might not work on your server.
+ * administrator
+ plugin must be setup correctly in order to detect administrative user.
+ See plugins/administrator/INSTALL
