46f33521 18Each of these steps is covered in detail below.
17cec454 19
238d4cfc 20- Install webserver and PHP (at least 4.1.0).
46f33521 21- Install IMAP server (see docs of that server).
22- Unpack the SquirrelMail package in a web-accessible location.
23- Select a data-dir and attachment dir, outside the webtree (e.g. in /var).
24 The data-dir (for user prefs) should be owned by the user the webserver
512d4b31 25 runs as (e.g. www-data). The attachment dir (for uploading files as
46f33521 26 attachments) should be file mode 0730 and in the same group as the
27 webserver.
28- Run config/ from the command line. Use the D option to load
29 predefined options for specific IMAP servers, and edit at least the
30 Server Settings and General Options (datadir).
31- Browse to
32 to test your configuration for common errors.
33- Browse to to log in.

46f33521 39 If your webserver does not already have PHP you must configure it
40 to work with PHP. You need at least PHP v4.1.0. SquirrelMail uses
238d4cfc 41 the standard suffix .php for all PHP files.
598294a7 42
46f33521 43 You can find PHP at See the documentation that
44 comes with PHP for instructions how to set it up.
17cec454 45
512d4b31 46 The PHP IMAP extension is NOT necessary at all (but won't harm)!
46f33521 47 Below is a list of optional PHP extensions:
17cec454 48
0dc92cda 49 --with-ldap
50 Required for LDAP addressbooks
bee552c7 51
0dc92cda 52 --with-pear and --with-mysql
bee552c7 53 For MySQL storage of preferences or addressbooks. You will need PHP
1131d10f 54 compiled with --with-pgsql option, if you want to use PostgreSQL instead
bee552c7 55 of MySQL. You will need PHP with appropriate database extension, if you
1131d10f 56 want to use any other database.
0dc92cda 57
58 --with-openssl
59 Required for encrypted IMAP or SMTP connections (TLS)
61 --with-mcrypt
62 Can be used by SquirrelSpell plugin for encryption of personal
63 dictionaries
65 --with-iconv or --with-recode
66 Can be used by Eastern charset decoding functions
68 --enable-mbstring
bee552c7 69 Required for Japanese translation. Optional for translations that
0dc92cda 70 use non-ISO-8859-1 charset
17cec454 71
46f33521 72 If you want your users to attach files to their mails, make sure
73 File Uploads in php.ini is set to On.
17cec454 74
17cec454 75
46f33521 79 This depends a lot on the server your choose. See the documentation
80 that comes with your server.
598294a7 81
46f33521 82 If you're concerned about people accessing it directly, you can
83 limit access to only the IP of the webserver.
17cec454 85
ef1932a4 89 SquirrelMail is constantly being improved. Therefore you should always
46f33521 90 get the newest version around. Look at
ef1932a4 91 to see what it is. If you want to be bleeding edge you might want to
92 consider using the latest CVS version (with the latest and most
46f33521 93 fashionable bugs).
17cec454 94
95a. Download SquirrelMail
97 Get SquirrelMail from the address above if you do not have it or are
98 uncertain if you have the newest version. Untar (again tar xvfz
99 filename.tgz) SquirrelMail in a directory that is readable for your
100 webserver.
102b. Setting up directories
104 SquirrelMail uses two directories to store user configuration and
105 attachments that are about to be sent. You might want to have these
106 directories outside of your web tree.
108 The data directory is used for storing user preferences, like
109 signature, name and theme. When unpacking the sources this directory
b731cd83 110 is created as data/ in your SquirrelMail directory. This directory
17cec454 111 must be writable by the webserver. If your webserver is running as
b731cd83 112 the user "nobody" you can fix this by running:
65b14f90 113
390372b4 114 $ chown -R nobody data
115 $ chgrp -R nobody data
4bc627ae 116
117 Keep in mind that with different installations, the web server could
598294a7 118 typically run as userid/groupid of nobody/nobody, nobody/nogroup,
119 apache/apache or www-data/www-data. The best way to find out is to read
ff65039a 120 the web server's configuration file.
4bc627ae 121
17cec454 122 There also needs to be a directory where attachments are stored
123 before they are sent. Since personal mail is stored in this
124 directory you might want to be a bit careful about how you set it
125 up. It should be owned by another user than the webserver is running
126 as (root might be a good choice) and the webserver should have write
127 and execute permissions on the directory, but should not have read
128 permissions. You could do this by running these commands (still
129 granted that the webserver is running as nobody/nobody)
390372b4 131 $ cd /var/some/place
132 $ mkdir SomeDirectory
133 $ chgrp -R nobody SomeDirectory
134 $ chmod 730 SomeDirectory
17cec454 135
136 If you trust all the users on you system not to read mail they are
137 not supposed to read change the last line to chmod 777 SomeDirectory
598294a7 138 or simply use /tmp as you attachments directory.
140 If a user is aborting a mail but has uploaded some attachments to it
141 the files will be lying around in this directory forever if you do not
390372b4 142 remove them. To fix this, it is recommended to create a cron job that
143 deletes everything in the attachment directory. Something similar
4bc627ae 144 to the following will be good enough:
390372b4 145
146 $ cd /var/attach/directory
147 $ rm -f *
598294a7 148
4bc627ae 149 However, this will delete attachments that are currently in use by people
150 sending email when the cron job runs. You can either (1) make sure that
151 the cron job runs at an obscure hour and hope that nobody gets upset, or
152 (2) you can run a modified version of the commands above. Check out the
153 man pages for other commands such as 'find' or 'tmpreaper'.
598294a7 154
4bc627ae 155 One sample script you could set up that would erase all attachments, but
156 wouldn't erase preferences, address books, or the like (just in case your
598294a7 157 attachment directory is the same as your data directory) might look like
4bc627ae 158 this:
598294a7 159
4bc627ae 160 $ rm `find /var/attach/directory -atime +2 | grep -v "\." | grep -v _`
598294a7 161
4bc627ae 162 Remember to be careful with whatever method you do use, and to test out
163 the command before it potentially wipes out everyone's preferences.
17cec454 164
165c. Setting up SquirrelMail
cbd6543c 167 There are two ways to configure SquirrelMail. In the config/ directory,
be8e07f8 168 there is a perl script called that will aid you in the
390372b4 169 configuration process. This is the recommended way of handling
be8e07f8 170 the config.
390372b4 172 You can also copy the config/config_default.php file to config/config.php
be8e07f8 173 and edit that manually.
65b14f90 174
cbd6543c 175 After you've created a configuration, you can use your webbrowser to
13721b47 176 browse to http://your-squirrelmail-location/src/configtest.php.
cbd6543c 177 This will perform some basic checks on your config to make sure
178 everything works like it should.
65b14f90 183
429f8906 184 Point your browser at the URL at which SquirrelMail is installed. A
598294a7 185 possible example of this is:
bee552c7 186
598294a7 187
3d8fe250 188 It should be pretty straight forward to use. Some more documentation
429f8906 189 might show up one day or another.

2481e3c1 1996. TRANSLATIONS
598294a7 202 In order to use translated versions of SquirrelMail, you need
2481e3c1 203 to download and install locale packages that contain translations
598294a7 204 that you want to use with SquirrelMail.
2481e3c1 206 Locale packages can be downloaded from SquirrelMail SourceForge
207 project page.
598294a7 208
bee552c7 209
598294a7 210
512d4b31 211 Each translation contains an install script that copies the required files
212 into their appropriate locations. If you can't run that script, you can
213 extract the contents of translation packages into your SquirrelMail
214 directory.
598294a7 215
512d4b31 216 NOTE No.1: *-src.tar.gz, *-src.tar.bz2 and * archives do not contain
217 compiled translation files. You will need to run the compilelocales script
2481e3c1 218 in order to get all gettext binary translations.
598294a7 219
2481e3c1 220 NOTE No.2: You might need to restart your webserver before using translations.
221 If you can't do that, install your translations _before_ you use SquirrelMail.

c650b678 2247. PLUGINS
bee552c7 227 The SquirrelMail package includes some standard plugins. These plugins can be
512d4b31 228 enabled in the SquirrelMail configuration script.
c650b678 229
230 Included plugins can use additional configuration files:
231 * change_password
232 configuration file is required. Without it plugin defaults to invalid
233 backend. See plugins/change_password/README
234 * filters, fortune, mail_fetch, newmail, translate
235 configuration files are optional. See README files in plugin directories.
236 * squirrelspell
237 configuration is stored in plugins/squirrelspell/sqspell_config.php
238 Default configuration might not work on your server.
239 * administrator
bee552c7 240 plugin must be setup correctly in order to detect administrative user.
