About Roundcube
Roundcube is a browser-based email client for IMAP mailboxes. It has the feel of a desktop mail app and is often installed by hosting providers.
What it does
Roundcube lets you read, write and organise email from any modern web browser. It supports several sender identities, HTML and MIME messages, drag and drop folder management and a built-in address book. Searching, threaded message lists and spell checking make everyday mail handling faster. Plugins extend the client with features such as PGP encryption and extra address book sources. It is written in PHP and runs on a web server that you control.
Key features
- Drag and drop message management
- Address book with groups and LDAP lookup
- Support for HTML and MIME messages
- Spell checking and threaded message view
- Plugin API for extra features
Who it's for
Hosting providers, companies and self-hosters who want a webmail front end for their own mail server. It is also useful for people who prefer a familiar mail app layout inside the browser.
Pricing and good to know
Roundcube is licensed under the GPL and is free to use. Running it requires a PHP web server and an IMAP mail account to connect to. Feature availability and updates depend on the version you install. Security updates are published on the project site, so keep the installation current.
