SquirrelMail is a standards-based webmail package written in PHP. It includes built-in pure PHP support for the IMAP and SMTP protocols, and all pages render in pure HTML 4.0 (with no JavaScript required) for maximum compatibility across browsers. It has very few requirements and is very easy to configure and install. SquirrelMail has all the functionality you would want from an email client, including strong MIME support, address books, and folder manipulation.
PHP 4.1.0 or higher
For better performance, it is recommended that PHP be compiled with gettext support (--with-gettext)
If you are going to use an LDAP addressbook, PHP needs to be compiled for LDAP (--with-ldap)
