Introduction

Zimbra Collaboration includes the Zimbra MTA, the Zimbra LDAP server, and the Zimbra mailbox server. In a single-server installation, all components are installed on one server and require no additional manual configuration.

This installation guide is a quick start guide that describes the basic steps needed to install and configure Zimbra Collaboration in a direct network connect environment. In this environment, the Zimbra 10 server is assigned a domain for which it receives mail, and a direct network connection to the Internet. When Zimbra Collaboration is installed, you will be able to log on to the Zimbra 10 administration console to manage the domain and provision accounts. The accounts you create are able to send and receive external email.

Important Notice About Single Server Installations

Zimbra Collaboration is designed to be the only application suite installed on the server. As part of the installation process, Zimbra Collaboration bundles and installs various other third party and open source software, including Eclipse Jetty, Postfix, and OpenLDAP®. The versions installed have been tested and configured to work with Zimbra 10 software. See the Zimbra Daffodil Administrator Guide for a complete list of software.

You cannot install Zimbra Daffodil (v10) without a license.

The following table shows the default port settings when Zimbra Collaboration is installed.

Important: You cannot have any other web server, database, LDAP, or MTA server running, when you install Zimbra Collaboration. If you have installed any of those applications before you install Zimbra 10 software, disable them. During Zimbra Collaboration installation, Zimbra 10 makes global system changes that may break applications that are on your server.

Preparing Your Server Environment

To successfully install and run Zimbra Daffodil, ensure your system meets the requirements described in this section. System administrators should be familiar with installing and managing email systems.

Do not manually create the user zimbra before running the Zimbra 10 installation. The installation automatically creates this user and sets up its environment.

System Requirements

For the Zimbra Daffodil system requirements see System Requirements for Zimbra Daffodil at the end of this guide.

Modifying Operating System Configurations

Zimbra Collaboration runs on one of several operating systems, including Ubuntu® LTS, Red Hat® Enterprise Linux, CentOS, Rocky and Oracle Linux.

A full default installation of the Linux distribution that you select is required.

Zimbra recommends that the operating systems you use are updated with the latest patches that have been tested with Zimbra Collaboration. See the latest release notes to see the operating systems patch list that has been tested with Zimbra Collaboration.

Configuring High-Fidelity Document Preview

This section is applicable only if zimbra-onlyoffice package was not installed during the installation process.

The high-fidelity document preview feature requires the installation of LibreOffice or the LibreOffice-core package, depending on the operating system you are running.

If LibreOffice is installed, the system is automatically configured to use high-fidelity document preview. If LibreOffice is not installed, the preview engine from prior Zimbra Collaboration releases is used.

This can be accomplished with the appropriate Linux distribution’s package management systems:

  • For RHEL 7/8, install the libreoffice-core package:

yum install libreoffice
yum install libreoffice-core

  • For Ubuntu, install libreoffice:

apt-get install libreoffice

DNS Configuration Requirement

When you create a domain during the installation process, Zimbra Collaboration checks to see if you have an MX record correctly configured for that domain. If it is not, an error is displayed suggesting that the domain name have an MX record configured in DNS.

To send and receive email, the Zimbra 10 MTA must be configured in DNS with both A and MX records. For sending mail, the MTA uses DNS to resolve hostnames and email-routing information. To receive mail, the MX record must be configured correctly to route the message to the mail server.

You must configure a relay host if you do not enable DNS. After Zimbra Collaboration is installed, go to the administration console's Global Settings → MTA tab and:

  • Uncheck Enable DNS lookups.

  • Enter the relay MTA address to use for external delivery.

Even if a relay host is configured, an MX record is still required if the Zimbra Collaboration server is going to receive email from the Internet.

Overview of the Installation Process

When you run the install script, the process verifies that the correct prerequisite Zimbra application packages are available to be installed.

Zimbra 10 Application Packages

Zimbra 10 architecture includes open-source integrations using industry-standard protocols. The third-party software has been tested and configured to work with the Zimbra 10 software.

The following describes the Zimbra Collaboration application packages that are installed.

Zimbra 10 Core

This package includes the libraries, utilities, monitoring tools, and basic configuration files. Zimbra 10 Core is automatically installed on each server.

Zimbra 10 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 Zimbra Collaboration.

The Zimbra 10 LDAP server must be configured before any other servers.

You can set up LDAP replication, configuring a master LDAP server and replica LDAP servers.

Zimbra 10 Store

This package includes the components for the mailbox server, including Jetty, which is the servlet container the Zimbra 10 software runs within. The Zimbra 10 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.

Zimbra 10 MTA

Postfix is the open source mail transfer agent (MTA) that receives email via SMTP and routes each message to the appropriate Zimbra 10 mailbox server using Local Mail Transfer Protocol (LMTP). The Zimbra 10 MTA also includes anti-virus and anti-spam components.

Zimbra 10 Proxy

Zimbra 10 Proxy is a high-performance reverse proxy service for passing IMAP[S]/POP[S]/HTTP[S] client requests to other internal Zimbra Collaboration services using nginx. 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.

By default Zimbra 10 Proxy is configured to perform strict server name enforcement of the HTTP 'Host' header sent by clients for new installs. Strict server name enforcement may be disabled during the post-install configuration process in the Zimbra 10 Proxy configuration section or using the zimbraReverseProxyStrictServerNameEnabled configuration option. Please see the Zimbra 10 Proxy section of the administration guide for more details.
Zimbra 10 Modern Web App

This package includes the assets of the Zimbra 10 Modern Web App. This package is automatically installed on each server.

Zimbra 10 Memcached

This package is automatically selected when the Zimbra 10-Proxy package is installed and provides access to Memcached.

At least one server must run zimbra-memcached when the Zimbra 10 Proxy service is in use. You can use a single memcached server with one or more Zimbra 10 proxies.
Zimbra 10 SNMP

Installing this package is optional.

If you choose to install Zimbra 10-SNMP for monitoring, this package should be installed on every Zimbra 10 server.
Zimbra 10 Logger

Installing this package is optional. It is installed on one mailbox server. It provides tools for syslog aggregation and reporting.

  • If you do not install Zimbra 10 Logger, the server statistics section of the administration console will not display.

  • The Zimbra 10 Logger package must be installed at the same time as the Zimbra 10 Store package.
Zimbra 10 Spell

This package is optional. It provides the open source spell checker Aspell used by the Zimbra 10’s web app.

Zimbra 10 Apache

This package is installed automatically when Zimbra 10 Spell or Zimbra 10 Convertd is installed.

Zimbra 10 Convertd

This package should be installed on at least one Zimbra 10-Store server. Only one Zimbra 10-Convertd package needs to be present in the Zimbra Collaboration environment. The default is to install one Zimbra 10-Convertd on each Zimbra 10-Store server.

Zimbra 10 Archiving

The Zimbra 10 Archiving and Discovery feature is an optional feature for Zimbra Collaboration. Archiving and Discovery offers the ability to store and search all messages that were delivered to or sent by Zimbra Collaboration. This package includes the cross mailbox search function which can be used for both live and archive mailbox searches.

Using Archiving and Discovery can trigger additional mailbox license usage. To find out more about Zimbra 10 Archiving and Discovery, please refer to Zimbra Daffodil Administration Guide.
Zimbra 10 OnlyOffice

This package installation is required for collaborative document editing of documents which is powered by Onlyoffice and enables collaborative editing of the documents stored in Briefcase. This package can be installed and setup on a Proxy server, Mailbox server or as a separate Document server.

The Zimbra 10 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 10 license xml file.

Downloading the Zimbra 10 Software

Obtain the Zimbra Collaboration software download and save to the computer from which you will install the software.

License Activation

All Zimbra Daffodil (v10) installations require license activation. New installations have a 10 day grace period from the license issue date before requiring activation. You can activate your license from the Administration Console.

Admin Console:

Home → Configure → Global Settings → License, from the Gear icon select Activate License

You can also activate your license from the command line interface.

Upgraded Zimbra Collaboration versions require an immediate activation to maintain network feature functionality.

Automatic License Activation

Licenses are automatically activated if the Zimbra Collaboration server has a connection to the Internet and can communicate with the Zimbra 10 License server. If you are unable to activate your license automatically, see the next section on Manual License Activation.

Manual License Activation

For systems that do not have external access to the Zimbra 10 License server, you can use the Zimbra 10 Support Portal to activate your license manually. Go to the Zimbra website at https://www.zimbra.com and click on Support to display the Zimbra 10 Technical Support page. Click on the Support Portal Login button to display the Zimbra 10 Support Portal page. Enter your email and password to log in.

If you have problems accessing the Support Portal, contact Zimbra Sales at sales@zimbra.com or by calling 1-972-407-0688.

When Licenses are not Installed or Activated

If you fail to install or activate your Zimbra Collaboration server license, the following scenarios describe how your Zimbra Collaboration server will be impacted.

License Condition Description/Impact

Not installed

With no installed license, the Zimbra Collaboration server defaults to single user mode where all license-limited features are limited to one user.

Not valid

If the license file appears forged or fails validation for other reasons, the Zimbra Collaboration server defaults to single-user mode.

Not activated

A license activation grace period is 10 days. If this period passes without activation, the Zimbra Collaboration server defaults to single-user mode.

For future date

If the license starting date is in the future, the Zimbra Collaboration server defaults to single-user mode.

In grace period

If the license ending date has passed and is within the 30 day grace period, all license-limited features are still enabled, but administrators may see license renewal prompts.

Expired

If the license ending date has passed, the 30 day grace period has expired, and users decide not to obtain a new license, they can resolve these issues by building their own binary (from the Zimbra 10 Source) and installing that on top of their existing system. The build version should be higher than the installed version.

Obtaining a License

Go to the Zimbra Website https://www.zimbra.com to obtain a trial license from the Network Downloads area. Contact Zimbra sales regarding a trial extended license, or to purchase a subscription license or perpetual license, by emailing sales@zimbra.com or calling 1-972-407-0688.

The subscription and perpetual license can only install on the Zimbra Collaboration system identified during purchase. Only one Zimbra 10 license is required for your Zimbra Collaboration environment. This license sets the maximum number of accounts on the system.

Current license information, including the number of accounts purchased, the number of accounts used, and the expiration date, can be viewed in the Admin Console.

Admin Console:

Home → Configure → Global Settings → License.

Installing Zimbra Collaboration Software

Important: Before you begin, make sure to:

  • Store your license in a directory folder on your server as it is needed to complete your installation of Zimbra Collaboration.

  • Confirm you have the latest system requirements and prerequisites for installing Zimbra Collaboration.

Open an SSH session to the Zimbra 10 server and follow the steps below:

  1. Log in as root to the Zimbra 10 server and cd to the directory where the Zimbra Collaboration archive tar file is saved (cd /var/<tmp>). Run the following commands:

    Unpack the file

    tar xvzf [zcsfullfilename.tgz]

    Change to the correct directory

    cd [zcsfullfilename]

    Begin the installation

    ./install.sh

    root@mailhost:/tmp# tar xzvf zcs*.tgz
zcs-NETWORK-10.0.0_GA_4452.UBUNTU18_64.20220911034542/
zcs-NETWORK-10.0.0_GA_4452.UBUNTU18_64.20220911034542/packages/
.
.
.
zcs-NETWORK-10.0.0_GA_4452.UBUNTU18_64.20220911034542/install.sh
zcs-NETWORK-10.0.0_GA_4452.UBUNTU18_64.20220911034542/README.txt

  2. The install.sh script reviews the installation software to verify that the Zimbra 10 packages are available. The installation process checks to see whether any of the applications Sendmail, Postfix, MySQL or MariaDB are running. If any of these applications are running, you are asked to disable them. Disabling MySQL and MariaDB is optional but highly recommended. Sendmail and Postfix must be disabled for Zimbra Collaboration to start correctly.

    root@zimbraiop:/tmp/# cd zcs-NETWORK-10.0.0_GA_4452.UBUNTU18_64.20220911034542/
root@zimbraiop:/tmp/zcs-NETWORK-10.0.0_GA_4452.UBUNTU18_64.20220911034542# ./install.sh

      cd /opt/zimbra/lib/ext/chat-video/

    2. Then create a config.properties text file in /opt/zimbra/lib/ext/chat-video/ with the following contents:

      chatVideoApiURL=https://api.chat.zimbra.com

    3. Create a config.domains.json text file in /opt/zimbra/lib/ext/chat-video/ and add the previously generated API Key and domain (replace the contents with the user API Key and domain after the colon:).

      [
    {
        "domain": "zimbra.com",
        "apiKey": "myApiKey"
    }
]

      Each API Key is unique and exclusive to each domain. Remember that to generate each API Key, user must log in to chat and video using the admin account of the corresponding domain. It is possible to configure more than one domain.

      In the example below, 2 domains are configured. Remember that each JSON object starts with { and ends with }. If it is more than one object, it must be separated by ,. Do not put , after the last one.

      [
    {
        "domain": "companyxpto.com",
        "apiKey": "fbg3QZA9vZS9KCB62kb2E3mVWZu6Ez67"
    },
    {
        "domain": "companyxyz.com",
        "apiKey": "6SbkuQa9h6Te5N9yxJsGaPnWGFhXk2an"
    }
]

  3. Grant permission to Zimbra chat and video domains:

     su - zimbra
 zmprov mc <COSname> +zimbraProxyAllowedDomains chat.zimbra.com +zimbraProxyAllowedDomains api.chat.zimbra.com

  4. Clear the zimlet cache

    zmprov flushCache zimlet

  5. Ensure that the zimlet is added to the relevant COSs

    Classic UI ⇒ zmzimletctl acl com_zimbra_chat_video <COSname> grant

    Modern UI ⇒ zmzimletctl acl zimbra-zimlet-chat-video <COSname> grant

  6. Enable chat for a user account or a COS or a Domain using the LDAP atribute zimbraFeatureModernChatEnabled. To enable it for a COS,

    zmprov mc <COSname> zimbraFeatureModernChatEnabled TRUE

  7. Restart the mailbox service

    zmmailboxdctl restart

Final Set-Up (required)

After the Zimbra Collaboration servers are configured, the following functions must be configured.

Zimbra Collaboration supports the default syslog of a supported operating system. Depending on your operating system, the steps contained in this section might not be correct. See your operating system documentation for specific information on how to enable syslog.

If zimbra-logger is installed, set up the syslog configuration files to enable server statistics to display on the administration console, and enable the logger monitor host. The server statistics includes information about the message count, message volume, and anti-spam and anti-virus activity.

Access to the 'zimbra' user

Zimbra Collaboration ships a default zimbra user with a disabled password. Zimbra Collaboration requires access to this account via ssh public key authentication. On most operating systems this combination is okay, but if you have modified spam rules to disallow any ssh access to disabled accounts then you must define a password for the zimbra UNIX account. This will allow ssh key authentication for checking remote queues. See the Zimbra wiki article, Mail Queue Monitoring.

Set up the ssh keys

To populate the ssh keys

sudo -u zimbra -i
zmupdateauthkeys

The key is updated on /opt/zimbra/.ssh/authorized_keys

Enabling Server Statistics Display

In order for the server statistics to display on the administration console, the syslog configuration files must be modified.

Note, your system may use a different provider for the syslog service. See the Wiki article Configuring Logger Host for more information

  1. As root, type the following command to enable the server to display statistics - /opt/zimbra/libexec/zmsyslogsetup.

  2. You must enable syslog to log statistics from remote machines.

RedHat Systems

  • Edit the /etc/sysconfig/syslog file to add -r to the SYSLOGD_OPTIONS setting, SYSLOGD_options="-r -m 0"

  • Stop the syslog daemon - /etc/init.d/syslog stop

  • Start the syslog daemon - /etc/init.d/syslog start

Debian and Ubuntu Systems

  • Edit the /etc/default/syslogd file to add -r to the SYSLOGD_OPTIONS setting, SYSLOGD_options="-r -m 0"

  • Stop the syslog daemon - /etc/init.d/sysklogd stop

  • Start the syslog daemon - /etc/init.d/sysklogd start

Final Set-Up (optional)

Ephemeral Data Migration

Versions of Zimbra prior to 9.0.0 stored ephemeral data in LDAP. Examples of ephemeral data include:

  • zimbraAuthTokens

  • zimbraCsrfTokenData

  • zimbraLastLogonTimestamp

Zimbra Collaboration versions after 9.0.0 introduced the ability to store ephemeral data in an external service such as SSDB. This is an optional feature; however, it can improve LDAP performance and stability.

Please refer to the Zimbra Daffodil Administration Guide for more information. Migration of ephemeral data out of LDAP and into SSDB must be performed after an install or upgrade has been completed.

Settings to enable ActiveSync for users

You can enable the ActiveSync feature for a single user or all the users under the cos.

To enable on cos:

zmprov mc "cos_name" zimbraFeatureMobileSyncEnabled TRUE
zmprov mc "cos_name" zimbraMobileShareMailEnabled TRUE
zmprov mc "cos_name" zimbraMobileShareContactEnabled TRUE
zmprov mc "cos_name" zimbraMobileShareCalendarEnabled TRUE

To enable for an individual user:

zmprov ma "user_name" zimbraFeatureMobileSyncEnabled TRUE
zmprov ma "user_name" zimbraMobileShareMailEnabled TRUE
zmprov ma "user_name" zimbraMobileShareContactEnabled TRUE
zmprov ma "user_name" zimbraMobileShareCalendarEnabled TRUE

Settings to enable Public Document Sharing in Briefcase

By default, Public Sharing is disabled for users.

To enable public sharing on the global level:

zmprov mcf zimbraPublicServiceProtocol https
zmprov mcf zimbraPublicServiceHostname <public hostname>

Scanning Attachments in Outgoing Mail

You can enable real-time scanning of attachments in outgoing emails sent using the Zimbra 10 Web Client. If enabled, when an attachment is added to an email, it is scanned using ClamAV prior to sending the message. If ClamAV detects a virus, it will block attaching the file to the message. By default, scanning is configured for a single node installation.

To enable using a single node:

zmprov mcf zimbraAttachmentsScanURL clam://localhost:3310/
zmprov mcf zimbraAttachmentsScanEnabled TRUE

Provisioning Accounts

Once the mailbox server is running, open your browser, enter the administration console URL and log on to the console to provision email accounts. The administration console URL is entered as:

https://[mailhost.example.com]:7071
To go to the administration console, you must type https, even if you configured the Web server mode as HTTP.

The first time you log on, a warning may be displayed stating the connection is untrusted. This only applies the first time you log in. Click I understand the Risks to be able to connect to the Zimbra 10 administration console. Then click OK.

Enter the admin user name and password configured during the installation process. Enter the name as admin@mailhost.example.com

Activate the Zimbra Daffodil (v10) license

Admin Console:

After you log on, a dialog displays stating your license is not activated.

Go to:

Home > Configure > Global Settings > License

click Activate License on the toolbar then Click OK to continue.

Provision accounts

You can configure one account at a time with the New Account Wizard or you can create many accounts at once using the Account Migration Wizard.

Configuring One Account

Admin Console:

The administration console New Account wizard steps you through the account information to be completed.

  1. From the administration console Home page’s Content pane, go to Add Accounts.

    Four accounts will already be listed - the admin account, two spam training accounts, and a global Documents account. These accounts do not need any additional configuration.

  2. Click Add Account. The first page of the New Account wizard opens.

  3. Enter the account name to be used as the email address and the last name. This is the only required information to create an account.

  4. You can click Finish at this point, and the account is configured with the default COS and global features.

To configure aliases, forwarding addresses, and specific features for this account, proceed through the dialog before you click Finish.

When the accounts are provisioned, you can send and receive emails.

Administrator Account

Initial administrative tasks when you log on for the first time may include setting up the admin mailbox to include features, aliases, and forwarding addresses needed for the administrator’s working environment.

Two aliases for the admin account are created during install:

  • Postmaster. The postmaster address is displayed in emails that are automatically generated from Postfix when messages cannot be sent. If users reply to this address, the message is forwarded to the admin mailbox.

  • Root. This address is where notification messages from the operating system are sent.

If you entered a notification address for AV alerts when you configured the MTA, that is different from the default, you need to create that account in the administration console. If you didn’t change the default during installation, the anti-virus notification is sent directly to the admin account.

Uninstalling Zimbra Collaboration

To uninstall servers, run the install script -u, delete the Zimbra Collaboration directory, and remove the zcs.tgz file on the servers.

  1. cd to the original install directory for the Zimbra Collaboration files.

  2. Type sudo ./install.sh -u

  3. When Completely remove existing installation? is displayed, type Yes. The Zimbra 10 servers are stopped, the existing packages, webapp directories, and most of the contents of the /opt/zimbra directory are removed.

  4. Type rm -rf [zcsfullfilename] to delete the Zimbra Collaboration directory.

  5. Delete the zcs.tgz file.
