Zimphony Webmail Free is a free white-label webmail and admin workspace layer for Zimbra deployments.

It is designed for organizations, hosting providers, and service providers that want to offer a branded customer-facing webmail experience while keeping Zimbra as the mail backbone.

Zimphony runs alongside an existing Zimbra mail backend. It does not replace Zimbra. Instead, it provides a clean, branded webmail workspace with Mail UI, Contacts, Admin UI at /admin, 2FA support, and migration/import/export support.

The Free package is license-free and does not require a Zimphony License Server connection.

Deployment is simple: the package runs as a two-container Docker deployment:

• frontend container: serves the Mail UI at / and the Admin UI at /admin
• backend container: serves the Webmail API and Admin API

There is no separate Admin frontend container.

Current target: Zimbra 10.
Earlier Zimbra versions may be evaluated case-by-case.
