Installation of SquirrelMail on Linux CentOS4.3

SquirrelMail is a web-based email application started by Nathan and Luke Ehresman and written in the PHP scripting language. It can be installed on almost all web servers as long as PHP is present and the web server has access to an IMAP and SMTP server. SquirrelMail outputs valid HTML 4.0 for its presentation, making it compatible with a majority of current web browsers. SquirrelMail uses a plugin architecture to accommodate additional features around the core application, and over 200 plugins are available on the SquirrelMail website.
