Roundcube Webmail is a free browser-based multilingual IMAP client with an application-like user interface.

It provides full functionality you expect from an email client, including MIME support, address book, folder manipulation, message searching, and spell checking.

This project is a free and open-source webmail solution with a desktop-like user interface that is easy to install/configure and that runs on a standard LAMPP server.

The skins use the latest web standards to render a functional and customizable UI.

Roundcube Webmail includes other sophisticated open-source libraries such as PEAR, an IMAP library derived from IlohaMail the TinyMCE rich text editor, Googiespell library for spell checking, or the WasHTML sanitizer by Frederic Motte.
