Deployment

Deploy modern Webmail around your existing Zimbra.

Zimphony Webmail runs on-premise as a Docker-based layer around your existing Zimbra environment. Zimbra remains the mail backend, and your mailboxes and data stay in place.

Deployment topology

Choose where Zimphony belongs in your environment.

Separate Host / VM and Same Zimbra Server are both supported. The installation flow remains essentially the same; the proxy arrangement changes to avoid conflicts.

01

Separate Host / VM

Public hostnameHTTPS + reverse proxy
Zimphony WebmailSeparate Linux host / VM
↔User + Admin SOAP
Existing ZimbraMail backend and data remain in place

Run Zimphony alongside the existing Zimbra web client without a disruptive cutover.

02

Same Zimbra Server

Zimbra ProxyPort 443 unchanged
Zimphony ProxyAnother available HTTPS port
Preferred low-impact arrangementNo proxy-port conflict. 10443 is an example only, not a fixed requirement.
Alternative environment arrangement

Zimphony may use 443 if the existing Zimbra proxy is moved to another non-conflicting port. This is not required.

Host requirements

Prepare a host that can run the Docker stack.

These are the current public readiness requirements. Detailed commands and network guidance belong in the technical installation guide.
