If you have installed any of the applications, before you install Zimbra software, disable these applications. During the ZCS install, Zimbra makes global system changes that may break applications that are on your server.

When Zimbra spell is installed, Zimbra-Apache is also installed. • Zimbra SNMP installs the SNMP package for monitoring. This package is optional. • Zimbra Logger installs tools for syslog aggregation, reporting, and message tracing. If you do not install Logger, you cannot use the message trace feature, the server statistics are not captures, and the server statistics section of the administration console does not display. • Zimbra Proxy installs the proxy feature. Using an IMAP/POP proxy server allows mail retrieval for a domain to be split across multiple Zimbra servers on a per user basis. • Zimbra Archiving installs the Zimbra Archiving and Discovery feature. This is an optional feature for ZCS Network Edition that offers the ability to store and search all messages that were delivered to or sent by ZCS. When this package is installed on the mail server, the cross mailbox search function is enabled. Using the Archiving and Discovery feature can trigger additional mailbox license usage. To find out more about Zimbra Archiving and Discovery, contact Zimbra sales. The Zimbra server configuration is menu driven. The installation menu shows you the default configuration values. The menu displays the logical host name and email domain name [mailhost.example.com] as configured on the computer. You can change any of the values. For single server installs, you must define the administrator’s password, which you use to log on to the administration console, and you specify the location of the Zimbra license xml file.
