How to configure Squirrelmal in Linux

SquirrelMail (From wiki) is an Open Source project that provides both a web-based email application and an IMAP proxy server. SquirrelMail webmail outputs valid HTML 4.0 for its presentation, making it compatible with a majority of current web browsers. SquirrelMail webmail uses a plugin architecture to accommodate additional features around the core application, and over 200 plugins are available on the SquirrelMail website


NOTE: Please make sure you have a working SMTP server and IMAP server because there are chances if your IMAP server is not up and running properly you will receive error at the end of the configuration.

To install squirrel mail you will need to download the tar file.

here is a link where you can find one
http://squirrelmail.org/download.php


make a directory inside /var/www/
# mkdir /var/www/mail
and unzip the file tar file inside this directory. You can use this command for that

# tar -tjvf squirrelmail.x.x.x.tar.bz2

you might also need php and php-imap to install PHP supports for Apache/IMAP.
# yum -y install php php-imap
# cd /var/www/mail
Now make one symlink for the squirrelmail.x.x.x
# ln -s squirrelmail.x.x.x/ mail
you can check the symlinks
# ls -l
Now just edit your apache configuration file with the virtual host entry
# vi /etc/httpd/conf/httpd.conf
(at the end of the file)
<VirtualHost 192.x.x.x:80>
ServerAdmin mail@server.example.com
DocumentRoot /var/www/mail/
<Directory /var/www/mail>
Options FollowSymlinks
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
Here server is the name of your machine and example.com is the domain name so change as per your machine hostname and domain name.

IP used is your machine’s IP.

Restart the apache server
# service httpd restart

Now configure the squirrel mail server
# cd /var/www/mail/mail/config/
# ./config.pl
And follow the instructions to edit your squirrelmail as per your requirements.

You also might need to Create ‘attach‘ and ‘data‘ directories for SquirrelMail:
# mkdir /var/local/squirrelmail/{data,attach}
(if you go for default settings)
Change the ownership of both these files to apache
# chown -R apache:apache /var/local/squirrelmail/
Go to the browser and mention the ip of your machine

http://192.168.x.x/mail

you will get the login page and try logging with one of your self created user
