46f33521 150. QUICK INSTALL GUIDE
16----------------------
17cec454 17
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/conf.pl 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).
a3bb5005 31- Browse to http://example.com/yourwebmaillocation/src/configtest.php
46f33521 32 to test your configuration for common errors.
a3bb5005 33- Browse to http://example.com/yourwebmaillocation/ to log in.

238d4cfc 361. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP
37--------------------------------------------
17cec454 38
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
a3bb5005 43 You can find PHP at http://php.net. See the documentation that
46f33521 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)
60
61 --with-mcrypt
62 Can be used by SquirrelSpell plugin for encryption of personal
63 dictionaries
64
65 --with-iconv or --with-recode
66 Can be used by Eastern charset decoding functions
67
68 --enable-mbstring
bee552c7 69 Required for Japanese translation. Optional for translations that
0dc92cda 70 use non-ISO-8859-1 charset
17cec454 71
962a6686 72 It is highly advised to NOT turn on register_globals, as this can lead
73 to security holes. If you must use register_globals for some applications,
74 turn it on locally for only those directories, or turn it off for the
75 SquirrelMail folder.
46f33521 76 If you want your users to attach files to their mails, make sure
77 File Uploads in php.ini is set to On.
17cec454 78
17cec454 79
802. SETTING UP IMAP
81------------------
82
46f33521 83 This depends a lot on the server your choose. See the documentation
84 that comes with your server.
598294a7 85
46f33521 86 If you're concerned about people accessing it directly, you can
87 limit access to only the IP of the webserver.

17cec454 89
903. OBTAINING AND INSTALLING SQUIRRELMAIL
91----------------------------------------
92
ef1932a4 93 SquirrelMail is constantly being improved. Therefore you should always
a3bb5005 94 get the newest version around. Look at http://squirrelmail.org
ef1932a4 95 to see what it is. If you want to be bleeding edge you might want to
8fea605c 96 consider using the latest SVN version (with the latest and most
46f33521 97 fashionable bugs).
17cec454 98
99a. Download SquirrelMail
100
101 Get SquirrelMail from the address above if you do not have it or are
102 uncertain if you have the newest version. Untar (again tar xvfz
103 filename.tgz) SquirrelMail in a directory that is readable for your
104 webserver.
105
106b. Setting up directories
107
108 SquirrelMail uses two directories to store user configuration and
109 attachments that are about to be sent. You might want to have these
110 directories outside of your web tree.
111
112 The data directory is used for storing user preferences, like
368ab966 113 signature, name and theme. You need to create this directory yourself.
114 Recommended location is under /var, for example:
115 /var/local/squirrelmail/data
116 This directory must be writable by the webserver. If your webserver is
117 running as the user "nobody" and group "nobody" you can fix this by
118 running:
65b14f90 119
e71e5745 120 $ chown -R nobody:nobody /var/local/squirrelmail/data
4bc627ae 121
122 Keep in mind that with different installations, the web server could
598294a7 123 typically run as userid/groupid of nobody/nobody, nobody/nogroup,
124 apache/apache or www-data/www-data. The best way to find out is to read
ff65039a 125 the web server's configuration file.
4bc627ae 126
17cec454 127 There also needs to be a directory where attachments are stored
128 before they are sent. Since personal mail is stored in this
129 directory you might want to be a bit careful about how you set it
130 up. It should be owned by another user than the webserver is running
e71e5745 131 as (root might be a good choice) and the webserver should have directory
132 write and execute permissions, but should not have read
17cec454 133 permissions. You could do this by running these commands (still
e71e5745 134 granted that the webserver is running as nobody/nobody):
17cec454 135
e71e5745 136 $ cd /var/local/squirrelmail/
137 $ mkdir attach
138 $ chgrp -R nobody attach
139 $ chmod 730 attach
17cec454 140
e71e5745 141 If you trust all the users at your system not to read mail they are
368ab966 142 not supposed to read, you can simply use /tmp as you attachments
143 directory.
598294a7 144
145 If a user is aborting a mail but has uploaded some attachments to it
146 the files will be lying around in this directory forever if you do not
390372b4 147 remove them. To fix this, it is recommended to create a cron job that
148 deletes everything in the attachment directory. Something similar
4bc627ae 149 to the following will be good enough:
390372b4 150
368ab966 151 $ cd /var/local/squirrelmail/attach
390372b4 152 $ rm -f *
598294a7 153
4bc627ae 154 However, this will delete attachments that are currently in use by people
155 sending email when the cron job runs. You can either (1) make sure that
156 the cron job runs at an obscure hour and hope that nobody gets upset, or
157 (2) you can run a modified version of the commands above. Check out the
158 man pages for other commands such as 'find' or 'tmpreaper'.
598294a7 159
4bc627ae 160 One sample script you could set up that would erase all attachments, but
161 wouldn't erase preferences, address books, or the like (just in case your
598294a7 162 attachment directory is the same as your data directory) might look like
4bc627ae 163 this:
598294a7 164
368ab966 165 $ rm `find /var/local/squirrelmail/attach -atime +2 | grep -v "\." | grep -v _`
598294a7 166
4bc627ae 167 Remember to be careful with whatever method you do use, and to test out
168 the command before it potentially wipes out everyone's preferences.
17cec454 169
170c. Setting up SquirrelMail
171
86bb50f8 172 There are three ways to configure SquirrelMail. In the config/ directory,
be8e07f8 173 there is a perl script called conf.pl that will aid you in the
390372b4 174 configuration process. This is the recommended way of handling
be8e07f8 175 the config.
176
86bb50f8 177 There's also a plugin called 'administrator' for the webinterface but you'll
178 have to be able to at least log in to SquirrelMail first.
179
390372b4 180 You can also copy the config/config_default.php file to config/config.php
be8e07f8 181 and edit that manually.
65b14f90 182
cbd6543c 183 After you've created a configuration, you can use your webbrowser to
13721b47 184 browse to http://your-squirrelmail-location/src/configtest.php.
e71e5745 185 This will perform some basic checks on your configuration to make sure
cbd6543c 186 everything works like it should.
187
188
17cec454 1894. RUNNING SQUIRRELMAIL
190-----------------------
65b14f90 191
429f8906 192 Point your browser at the URL at which SquirrelMail is installed. A
598294a7 193 possible example of this is:
a3bb5005 194 http://example.com/squirrelmail
598294a7 195
3d8fe250 196 It should be pretty straight forward to use. Some more documentation
429f8906 197 might show up one day or another.

2481e3c1 2076. TRANSLATIONS
208---------------
209
598294a7 210 In order to use translated versions of SquirrelMail, you need
2481e3c1 211 to download and install locale packages that contain translations
598294a7 212 that you want to use with SquirrelMail.
213
2481e3c1 214 Locale packages can be downloaded from SquirrelMail SourceForge
215 project page.
598294a7 216
bee552c7 217 http://sourceforge.net/project/showfiles.php?group_id=311&package_id=110388
598294a7 218
512d4b31 219 Each translation contains an install script that copies the required files
220 into their appropriate locations. If you can't run that script, you can
86bb50f8 221 extract the contents of a translation package into your SquirrelMail
512d4b31 222 directory.
598294a7 223
512d4b31 224 NOTE No.1: *-src.tar.gz, *-src.tar.bz2 and *-src.zip archives do not contain
86bb50f8 225 compiled translation files. You will need to run the "compilelocales" script
2481e3c1 226 in order to get all gettext binary translations.
598294a7 227
2481e3c1 228 NOTE No.2: You might need to restart your webserver before using translations.
229 If you can't do that, install your translations _before_ you use SquirrelMail.

c650b678 2327. PLUGINS
233----------
234
bee552c7 235 The SquirrelMail package includes some standard plugins. These plugins can be
512d4b31 236 enabled in the SquirrelMail configuration script.
c650b678 237
238 Included plugins can use additional configuration files:
239 * change_password
240 configuration file is required. Without it plugin defaults to invalid
241 backend. See plugins/change_password/README
242 * filters, fortune, mail_fetch, newmail, translate
243 configuration files are optional. See README files in plugin directories.
244 * squirrelspell
245 configuration is stored in plugins/squirrelspell/sqspell_config.php
e71e5745 246 The default configuration might not work at your server.
c650b678 247 * administrator
bee552c7 248 plugin must be setup correctly in order to detect administrative user.
c650b678 249 See plugins/administrator/INSTALL
