Zimbra Mp [FREE]

  • Redundant MTAs: Inbound MX records should point to at least two MTA public IPs.
  • Split DNS: Configure internal DNS to resolve mail.yourdomain.com to Proxy IPs, not Internet IPs.
  • Licensing: Multi-Server requires a Network Edition license (or special open-source agreement for multi-node). The Zimbra OSE binary build does not officially support multiple mailbox stores.

    • Zimbra MP is a strategic, forward-looking rearchitecture of the classic Zimbra Collaboration Suite. It delivers substantial gains in performance, scalability, and developer experience at the cost of migration complexity and infrastructure overhead. For organizations seeking a modern, self-hosted collaboration platform with a strong API-first design, Zimbra MP is a viable competitor to Microsoft Exchange Online and Google Workspace, particularly in privacy-conscious or air-gapped environments.

    As classic ZCS approaches end-of-life, Zimbra MP will become the standard deployment model for all new and migrating customers.

    Based on Postfix, MTA servers handle incoming and outgoing SMTP traffic. In a single-server setup, mail lands directly on the mailbox server. In Zimbra MP, MTAs act as a front-line relay. They perform anti-spam (Amavis), anti-virus (ClamAV), and then route mail to the correct backend mailbox node.

    Out of the box, Zimbra MP supports system-level dark mode detection. This is a default feature, not a hack. The UI also meets WCAG 2.1 AA standards for accessibility.
