Roundcube Webmail

RoundCube Webmail is a free, international IMAP client that works in any browser and has a user interface that looks like an app. It has all the features you'd expect from an email client, like spell checking, MIME support, an address book, the ability to change folders, and the ability to find messages.

This project is a free and open-source webmail service with a user interface that looks like a desktop. It's simple to set up and runs on a normal LAMPP server. The skins use the most up-to-date web standards to make a UI that works and can be changed. It comes with advanced open-source tools like PEAR (an IMAP library based on IlohaMail), the TinyMCE rich text editor, the Googiespell library for checking spelling, and Frederic Motte's WasHTML sanitizer.
