1 1. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP4
2 ---------------------------------------------
3
4 If your webserver does not already have PHP4 you must configure it
5 to work with PHP4. SquirrelMail uses the standard suffix .php for
6 all PHP4 files. This is a quick and dirty guide to installing PHP4
7 to run as CGI under Apache. How you end up doing this is up to you
8 (your mileage may vary).
9
10 a. Obtaining and compiling PHP4
11
12 Point your favorite webserver at http://www.php.net/version4/ and
13 download the source. Untar (tar xvfz filename-you-downloaded.tgz)
14 the source, cd into the directory and run configure. To make PHP4
15 work with SquirrelMail a commandline like this should do:
16
17 ./configure --enable-track-vars --enable-force-cgi-redirect --with-gettext
18
19 If you have a database like MySQL you might want to add something
20 like --with-mysql to get database functionality.
21
22 If you're going to use LDAP in the addressbook, you must compile PHP4
23 with --with-ldap (see the PHP4 docs for more information).
24
25 Run make to build the binary file. This will generate a binary file
26 called "php". Move this file into a CGI-directory.
27
28 You might also want to read the INSTALL file in the PHP-distribution
29 :-)
30
31 b. Changing php.ini
32
33 PHP defaults to look for php.ini (PHP's configuration file) in
34 /usr/local/lib. However, for security reasons, it is suggested
35 that the location of this file is changed to someplace else. This
36 can be done at configure time with the configuration directive
37 --with-config-file-path=PATH.
38
39 Edit the php.ini file and make sure session.use_cookies is 1. Also
40 be sure to change the session.save_path to someplace that can only
41 be read and written to by the webserver. session.save_path is the
42 location that PHP's session data will be written to.
43
44 SECURITY WARNING - If a user has access to write PHP scripts on your
45 system and knows the location where PHP stores session data, he
46 could get a listing of the sessions being used and then read a given
47 session's data with his own PHP script. Caution should be used when
48 setting up permissions and locations of php.ini and the session data.
49
50 c. Setting up .php files to use PHP4
51
52 You need to create a .htaccess file in you SquirrelMail directory
53 that looks something like this:
54
55 AddType application/php4script .php
56 Action application/php4script /cgi-bin/php
57
58 You could also add these lines to your Apache configuration file.
59
60 d. Running into trouble
61
62 Setting up Apache with PHP4 can be a non-trivial task. Read the PHP4
63 and Apache documentation carefully if you run into trouble. If you
64 have an experienced system administrator around ask her/him to help
65 you.

67 2. SETTING UP IMAP
68 ------------------
69
70 This is not covered here :-/
71
72 3. OBTAINING AND INSTALLING SQUIRRELMAIL
73 ----------------------------------------
74
75 SquirrelMail is still under development. Therefore you should always
76 get the newest version around. Look at
77 http://squirrelmail.sourceforge.net/index.php3?page=5 to see what it
78 is. If you want to be bleeding edge you might want to consider using
79 the latest CVS version (with the latest and most fashionable of
80 bugs).
81
82 a. Download SquirrelMail
83
84 Get SquirrelMail from the address above if you do not have it or are
85 uncertain if you have the newest version. Untar (again tar xvfz
86 filename.tgz) SquirrelMail in a directory that is readable for your
87 webserver.
88
89 b. Setting up directories
90
91 SquirrelMail uses two directories to store user configuration and
92 attachments that are about to be sent. You might want to have these
93 directories outside of your web tree.
94
95 The data directory is used for storing user preferences, like
96 signature, name and theme. When unpacking the sources this directory
97 is created as data/ in you SquirrelMail directory. This directory
98 must be writable by the webserver. If your webserver is running as
99 the user nobody you can fix this by running:
100
101 chown -R nobody data
102 chgrp -R nobody data
103
104 There also needs to be a directory where attachments are stored
105 before they are sent. Since personal mail is stored in this
106 directory you might want to be a bit careful about how you set it
107 up. It should be owned by another user than the webserver is running
108 as (root might be a good choice) and the webserver should have write
109 and execute permissions on the directory, but should not have read
110 permissions. You could do this by running these commands (still
111 granted that the webserver is running as nobody/nobody)
112
113 cd /var/some/place
114 mkdir SomeDirectory
115 chgrp -R nobody SomeDirectory
116 chmod 730 SomeDirectory
117
118 If you trust all the users on you system not to read mail they are
119 not supposed to read change the last line to chmod 777 SomeDirectory
120 or simply use /tmp as you attachments directory. If a user is
121 aborting a mail but has uploaded som attachments to it the files
122 will be lying around in this directory forever if you do not remove
123 them.
124
125 c. Setting up SquirrelMail
126
127 There are two ways to configure Squirrelmail. In the config/ directory,
128 there is a perl script called conf.pl that will aid you in the
129 configuration process. This is the most recommended way of handling
130 the config.
131
132 You can also copy the config/config_default.php file to config.php
133 and edit that manually.
134
135 4. RUNNING SQUIRRELMAIL
136 -----------------------
137
138 Point your browser at the URL at which SquirrelMail is installed. It
139 should be pretty stright forward to use. Some more documentation
140 might show up onbe day or another.

143 5. RUSSIAN CHARSETS
144 -------------------
145
146 For information on how to make SquirrelMail work with Russian
147 Apache, see the README.russian_apache in the doc/ subdirectory.
