 When you run the install script, the process verifies that the correct
 prerequisite Zimbra application packages are available to be installed.
 
-[[Zimbra_Application_Packages]]
-== {product-short} Application Packages
-
-{product-short} architecture includes open-source integrations using industry
-standard protocols. The third-party software has been tested and
-configured to work with the {product-short} software.
-
-The following describes the Zimbra packages that are installed.
-
-* *{product-short} Core:* This package includes the libraries, utilities,
-monitoring tools, and basic configuration files. {product-short} Core is
-automatically installed on each server.
-
-* *{product-short} Store:* The {product-short} store includes the components for the
-mailbox server, including Jetty, which is the servlet container the
-{product-short} software runs within. The {product-short} mailbox server includes the
-following components:
-** Data store: The data store is a MariaDB© database.
-** Message store: The message store is where all email messages and file
-attachments reside.
-** Index store: Index and search technology is provided through Lucene.
-Index files are maintained for each mailbox.
-** Web application services: The Jetty web application server runs web
-applications (webapps) on any store server. It provides one or more web
-application services.
-
-* *{product-short} LDAP:* User authentication is provided through OpenLDAP®
-software. Each account on the Zimbra server has a unique mailbox ID that
-is the primary point of reference to identify the account. The OpenLDAP
-schema has been customized for {product-name}. The {product-short} LDAP
-server must be configured before the other servers. You can set up LDAP
-replication, configuring a master LDAP server and replica LDAP servers.
-
-* *{product-short} MTA:* Postfix is the open source mail transfer agent (MTA)
-that receives email via SMTP and routes each message to the appropriate
-{product-short} mailbox server using Local Mail Transfer Protocol (LMTP). The
-{product-short} MTA also includes the anti-virus and anti-spam components.
-
-* *{product-short} Proxy:* {product-short} Proxy is a high-performance reverse proxy
-service for passing IMAP[S]/POP[S]/HTTP[S] client requests to other
-internal {product-name} services.This package is normally installed on the MTA
-server(s) or on its own independent server(s). When the `zimbra-proxy`
-package is installed, the proxy feature is enabled by default.
-Installing the {product-short} Proxy is required as of
-{product-abbrev} 8.7.
-
-
-* *{product-short} Memcached:* Memcached is automatically selected when the
-`zimbra-proxy` is installed. At least one server must run `zimbra-memcached`
-when the proxy is in use. You can use a single memcached server with one
-or more {product-short} proxies.
-
-* *{product-short} SNMP:* Installing the {product-short} SNMP package is optional. If you
-choose to install `zimbra-snmp` for monitoring, this package should be
-installed on every {product-short} server.
-
-* *{product-short} Logger:* Installing the {product-short} Logger package is optional and
-is installed on one mailbox server. The {product-short} Logger installs tools for
-syslog aggregation and reporting. If you do not install Logger, the
-server statistics section of the administration console will not
-display.
-+
-NOTE: The Logger package must be installed at the same time
-as the mailbox server.
-+
-
-* *{product-short} Spell:* Installing the {product-short} Spell package is optional.
-Aspell is the open source spell checker used on the {product-short} Web Client.
-
-* *{product-short} Apache:* This package is installed automatically when {product-short}
-Spell or {product-short} Convertd is installed.
-
-The {product-short} 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 {product-short} license xml file.
