15 Installing SquirrelMail
SquirrelMail is a webmail interface that will let your users send and receive emails in a browser. This chapter shows how to install it and adjust it to our setup so that users can even change their email account password from the SquirrelMail interface.
To install SquirrelMail, we run:
aptitude install squirrelmail php-pear
Next we copy the Apache configuration that comes with the SquirrelMail package to the /etc/apache2/conf.d directory and restart Apache:
cp /etc/squirrelmail/apache.conf /etc/apache2/conf.d/squirrelmail.conf
/etc/init.d/apache2 restart
SquirrelMail comes with some pre-installed plugins, unfortunately none of them is capable of letting us change our email password in our MySQL database. But there's the Change SQL Password plugin which we can install manually:
The plugin depends on the Pear-DB package so we install it:
pear install DB
Then we install the Change SQL Password plugin itself:
cd /usr/share/squirrelmail/plugins
wget http://www.squirrelmail.org/countdl.php?fileurl=http%3A%2F%2Fwww.squirrelmail.org%2Fplugins%2Fchange_sqlpass-3.3-1.2.tar.gz
tar xvfz change_sqlpass-3.3-1.2.tar.gz
cd change_sqlpass
cp config.php.sample config.php
Now we must edit config.php and adjust it to our setup. Please adjust the $csp_dsn, $lookup_password_query, $password_update_queries, $password_encryption, $csp_salt_static, and $csp_delimiter variables as follows and comment out $csp_salt_query:
vi config.php
[...] $csp_dsn = 'mysql://mail_admin:mail_admin_password@localhost/mail'; [...] $lookup_password_query = 'SELECT count(*) FROM users WHERE email = "%1" AND password = %4'; [...] $password_update_queries = array('UPDATE users SET password = %4 WHERE email = "%1"'); [...] $password_encryption = 'MYSQLENCRYPT'; [...] $csp_salt_static = 'LEFT(password, 2)'; [...] //$csp_salt_query = 'SELECT salt FROM users WHERE username = "%1"'; [...] $csp_delimiter = '@'; [...] |

The Change SQL Password plugin also depends on the Compatibility plugin which we install as follows:
cd /usr/share/squirrelmail/plugins
wget http://www.squirrelmail.org/countdl.php?fileurl=http%3A%2F%2Fwww.squirrelmail.org%2Fplugins%2Fcompatibility-2.0.16-1.0.tar.gz
tar xvfz compatibility-2.0.16-1.0.tar.gz
Now we must go into the SquirrelMail configuration and tell SquirrelMail that we use Courier as our POP3 and IMAP server and enable the Change SQL Password and the Compatibility plugins:
/usr/sbin/squirrelmail-configure
You'll see the following menu. Navigate through it as indicated:

While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don't work so
well with others. If you select your IMAP server, this option will
set some pre-defined settings for that server.
Please note that you will still need to go through and make sure
everything is correct. This does not change everything. There are
only a few settings that this will change.
Please select your IMAP server:
bincimap = Binc IMAP server
courier = Courier IMAP server
cyrus = Cyrus IMAP server
dovecot = Dovecot Secure IMAP server
exchange = Microsoft Exchange IMAP server
hmailserver = hMailServer
macosx = Mac OS X Mailserver
mercury32 = Mercury/32
uw = University of Washington's IMAP server
gmail = IMAP access to Google mail (Gmail) accounts
quit = Do not change anything
Command >> <-- courier
imap_server_type = courier
default_folder_prefix = INBOX.
trash_folder = Trash
sent_folder = Sent
draft_folder = Drafts
show_prefix_option = false
default_sub_of_inbox = false

Now you can type in http://server1.example.com/squirrelmail or http://192.168.0.100/squirrelmail in your browser to access SquirrelMail.
Log in with your email address (e.g. [email protected]) and your password:
You should find the welcome email in your inbox:
To change your password, go to Options and then select Change Password:
Type in your current password and then your new password twice:
If the password has been changed successfully, you will see the following error message which means you must log in again with your new password (because the old one isn't active anymore):
