SquirrelMail is a standards-based Webmail package which includes built-in pure PHP support for the IMAP and SMTP protocols.

Pages are rendered in pure HTML 4.0 for maximum compatibility across browsers. It has very few requirements, and is very easy to configure and install. It has all the functionality you would want from an email client, including strong MIME support, address books, and folder manipulation.
