“Zimbra MP” refers to a Multi-Node / Multi-Server installation. Instead of running all Zimbra services (MTA, LDAP, Mailbox, Proxy) on a single operating system instance, you distribute specific roles across multiple dedicated servers.

: Partners own the customer relationship, billing, and support lifecycle. zimbra mp

Zimbra Mobile Plus implements a 100% compliant Exchange ActiveSync stack. It uses a handler within the mailboxd service—through the Jetty web server—to accept incoming synchronization requests. The module listens on the same ports as the Zimbra webmail interface (usually port 80 for HTTP and port 443 for HTTPS). This is critical because most mobile ActiveSync clients do not allow custom port specifications; they expect to find the server on the default ports. “Zimbra MP” refers to a Multi-Node / Multi-Server

The implementation process was smooth, and Alex was able to configure the MFA settings within Zimbra's admin interface. Users were then required to download an authenticator app on their mobile devices, which would generate a time-based one-time password (TOTP) code.

To appreciate Zimbra MP, one must understand where it came from.
| Feature | Single-Server | Multi-Server (MP) | | :--- | :--- | :--- | | | Single point of failure. | Redundant LDAP, MTA, and Mailbox servers. | | Scalability | Limited to vertical scaling (bigger server). | Horizontal scaling (add more mailbox servers). | | Maintenance | Downtime required for updates/kernel patches. | Zero-downtime rolling maintenance. | | Performance | All services compete for RAM/CPU. | Dedicated resources for each role. | | Disaster Recovery | Complex; full server restore needed. | Easier; failed component can be rebuilt. |
