About Roundcube
Roundcube is webmail software you install on your own server to give users a browser-based client for an existing IMAP mail server. Its interface behaves like a desktop mail application, with drag-and-drop message handling, threaded message lists, spell checking and a responsive skin for phones and tablets.
It includes a full address book with groups and LDAP connectors, multiple sender identities, shared IMAP folders with access control lists, PGP encryption support and a plug-in API. Security updates are released regularly for both the 1.6 and 1.7 branches.
