The Zimbra server is a dedicated server that manages all of the mailbox contents, including messages, contacts, calendar, and attachments. Messages are received from the Zimbra MTA server and then passed through any filters that have been created. Messages are then indexed and deposited into the correct mailbox.
In addition to content management, the Zimbra mailbox server has dedicated volumes for backup and log files.
Each Zimbra mailbox server in the system can see only its own storage volumes. Zimbra mailbox servers cannot see, read, or write to another Zimbra server.
In a Zimbra single server environment, all services are on one server, and during installation the computer is configured to partition the disk to accommodate each of the services.
In a Zimbra multi-server environment, the Zimbra LDAP and Zimbra MTA services can be installed on separate servers. See the Multi-Server Installation Guide.
Key advantages include:
- compatibility with Windows, Mac, and Linux desktop environments;
- better scalability and ease of maintenance; and
- flexibility to integrate other applications as web services in our AJAX web client.
