Webmail is one of the most commonly used features in cPanel. As opposed to having email delivered from the server to a desktop application, Webmail allows users to check their messages from their browsers. Currently, there are three different Webmail applications available, each with their own subtle differences, but all with the same power to deliver secure email on the web.
The Horde Project is an open-source development community that is responsible for the creation of countless applications and software systems. Vetted and managed by a Core Team, Horde develops tools with PHP that are valuable for small businesses all the way up to the enterprise level. Their focus on enterprise tools has allowed them to create, not only a popular Webmail application, but also a suite of complementary widgets that do everything from managing calendars, notes, and addresses to standard filtering, message flagging, and the search functionality that comes with many Webmail platforms.
RoundCube is the world’s leading open source Webmail application. This application already has millions of users and the upcoming evolution of their product is guaranteed to garner even more attention from users around the world. While not equipped with as many additional features as Horde, RoundCube is praised for its easy-to-use, drag-and-drop interface. Loaded with the ability to search, flag, and organize your email, it makes perusing and managing your inbox (and outbox) super simple.
