Licence and source scope

Roundcube is GPL-licensed, rather than AGPL-licensed. Running its PHP engine as a hosted customer service does not by itself require publishing that server code. Browser-delivered components have their own redistribution requirements, which this source offer addresses.

Private server integrations, production configuration and customer data are not included. Customer-only operation does not restrict your rights under the included open-source licences. These components are provided without warranty as described in their licences.
