Most popular webmail client Roundcube gets enterprise support 

Meeting demand of mail providers for large deployments and directing resources towards the development of the open source webmail software project

Berlin, August 8, 2024 – Nextcloud is thrilled to announce the first official enterprise support offering for Roundcube, the world’s most popular on premise hosted webmail solution, tailored specifically for mail providers running large instances with tens of thousands to millions of end users.

Since joining Nextcloud in November 2023, Roundcube development has accelerated and communication channels such as user groups have been re-established. These developments have prompted requests for collaboration from service providers, looking to gain support for large deployments.

„The user feedback clearly indicated demand for enterprise support,“ said Frank Karlitschek, Founder & CEO Nextcloud. „The first official enterprise support offering since Roundcube’s initial launch in 2008 delivers on this need and will make Roundcube more accessible to large organisations, encouraging broader adoption of Roundcube and directing resources toward its development.“ 

The offering is complemented by a choice of optional email servers through partnerships with open-source mail server solution Stalwart and Dovecot Pro, the pioneer of open and trusted software and solutions for service providers worldwide. Additionally, full PGP based End-to-End Encryption for Roundcube Enterprise is provided through a collaboration with browser add-on Mailvelope, allowing users to encrypt and sign data and communications.

Future releases of Roundcube will be able to work with the new JMAP standard supported by Stalwart, modernizing and streamlining email management. Roundcube Enterprise is designed for mail providers, complementing the dedicated Nextcloud Mail solution integrated in Nextcloud Hub, which has a focus on providing collaboration services within enterprises.

Open source email pioneer Roundcube joined the Nextcloud family in November 2023 with the joint goal of becoming a new steward for a popular webmail client trusted in highly regulated industries and among security-savvy users alike. The open source webmail software project Roundcube was initially released in 2008 and is an important player in the role of email sovereignty, remaining highly relevant in today’s tech landscape. 

Hosting companies around the world such as HostGator, Media Temple, Gandi, OVH and others use Roundcube. In addition, Roundcube is used by several renowned universities such as Harvard University to provide email services to students and staff.

Frank Hoberg, founder at Open-Xchange, said: “Our partnership with Nextcloud brings together two major players in open-source based software to deliver an enterprise-grade email backend support option to the wider Roundcube community. Based on Dovecot Pro, this delivers an email backend with range of advanced features, including its exclusive high availability architecture, extended search, and document previews, along with the highest level of support for mission-critical email they demand.”

Mauro De Gennaro, president of Stalwart Labs LLC said: “We are excited to collaborate with Nextcloud on delivering a reliable and modern enterprise email platform to hosting providers across the globe.”

Thomas Oberndoerfer, founder of Mailvelope said: “We are excited to partner with Nextcloud to integrate our OpenPGP-based end-to-end encryption with Roundcube. This collaboration ensures that users can enjoy secure and private email communications seamlessly within their browser.”
