Roundcube
Roundcube Webmail is a free software for IMAP, which is developed in the programming languages PHP and JavaScript. Round Cubes most prominent features are the sleek and modern user interface and the pronounced use of Ajax technology that enables a similar ease of use as a locally installed application.
The project was started in 2005 with an alpha version. Meanwhile Roundcube has reached the version currently available a mature state.
Roundcube has a wide range of functions, such as a spelling checker, multi-language, send e -mail attachments, full support for MIME and HTML message formats and an LDAP address book. In addition, the functionality of Roundcube can be extended with plug-ins. It can thus be integrated, inter alia, a calendar and organizer. Numerous plug-ins can be found in the " plug- in repository ".
