Pricing and Packaging
Is Zimbra free?, What version do it need?
Zimbra has both a free Open Source Edition as well as a premium Network Edition.
- Here is the open source license info
- Here is the product editions comparison
- Here are the additional Network Edition Benefits
- What version is right for me?
Can you explain how the pricing works?
Pricing of Network Edition depends on the size of your installation and the type of business or organization you have. Generally speaking:
- The more mailboxes you purchase, the less you will pay per mailbox (sliding scale)
- Non-profits, government, education are eligible for discounted rates
- Service provides have pricing conducive for large-scale deployments
Here is an example:
- A business wanting 150 mailboxes of the Professional Edition: $28 x 150 = $4,200 per year. This license commitment is is eligible for Zimbra Basic Support.
- A government agency looking for the same: $14 x 150 = $2,100 per year. Also eligible for Zimbra Basic Support.
Can I get Zimbra if I want less than 25 mailboxes?
There are two options:
- Some customers purchase the minimum 25 licenses planning for growth
- Most try one of Zimbra's many hosting providers who will provide the services you need (Zimbra does not provide hosting to customers, we only sell ZCS for on-premise deployment)
Admin Field Guide: Installation & Configuration
Here's some gotchas we hear about from the Zimbra Community when installing and configuring ZCS. Hope this makes for smooth sailing!
What are the pre-requirements for installing the Zimbra server, how do I avoid install hassles?
- Do you have all the install pre-req's ironed out like compat-libstc++, selinux disabled, and port conflicts resolved. Installation will check and fail on any of these condition.
- Pre-requirement: For Red Hat Enterprise, Fedora Core and SuSE operating systems, the server must also have the following installed
- NPTL. Native POSIX Thread Library
- Sudo. Superuser, required to delegate admins.
- libidn. For internationalizing domain names in applications (IDNA)
- cURL. A command line tool for transferring files with URL syntax
- fetchmail. A remote-mail retrieval and forwarding utility used for on-demand TCIP/IP links.
- GMP. GNU Multiple-Precision Library.
- compat-libstdcc++-33. Compatibility Standard C++ libraries. ( NOTE: The 32-bit version of the compat-libstdc rpm package is required for both 32-bit or 64-bit servers. )
- For Red Hat Enterprise only: compatlibstdcc++-296
Avoiding conflicts: what are the default port configurations when Zimbra is installed?
Default port usage:
- Postfix 25
- HTTP 80
- POP3 110
- IMAP 143
- LDAP 389
- HTTPS 443
- Tomcat IMAP SSL 993
- Tomcat POP SSL 995
- Tomcat LMTP 7025
How do I make sure that DNS is configured correctly?
- Overview of MTA and DNS
- Make sure the default domain supplied in the DNS wizard is the actual email domain and not the FQDN of the box
What are the top issues affecting performance?
- Make sure that your client machines satisfy the system requirements for systems specs, operating system, and browser.
- Make sure the server machines meet the system requirements for hardware and operating system; size your hardware with growth in mind!
- Review the system requirements (PDF)
- Evaluation and testing: Intel/AMD 32-bit CPU 1.5 GHz, 1 GB RAM, 5 GB free disk space for software and logs, mail storage space
- Production: Intel/AMD CPU 32-bit 2.0+ GHz, 2+ GB RAM, 10 GB free disk space for software and logs, mail storage space.
- RAID-5 not recommended for installations with more than 100 accounts
How does the license key work?
- The license key is provided to you in the Network trial registration email from the Sales Team.
- When you do the installation you will automatically be provided a single user license (admin) to enable the install.
- From the Admin UI (Global Settings / License / Update License) you can then apply the key to the trial system and provision up to 50 accounts for the life of the trial.
- After the trial expires you will no longer be able to add new accounts but the ones you already have provisioned may still work for some time.
- Existing customers with license issues can always visit the Support Portal
I can't get to the Admin UI when I type in the URL into my browser.
- Make sure the URL connects to the Admin UI using SSL: "https" and to port ":7071" by default.
How do I change the Zimbra server's hostname?

We use Active Directory, what level of "access" into AD does Zimbra need to authenticate users?
- In order for Zimbra to use external AD/LDAP for authentication and/or GAL, you need to create a user that can see all user objects in the AD schema.
- Configuration of external auth/GAL is by means of an easy wizard in the Admin UI.
How do I access the Exchange migration tools?
- In the Admin UI select the Wizard tab, you will find migration tools and documentation
