Zimbra is an open platform solution that lets you manage and control your data the way you want it, while keeping it secure and private. With a modern user interface, Zimbra is easy to use and accessible anytime, anywhere.
A: The source code for Zimbra 9 is available in the Zimbra source code repository on GitHub. All client and server code is available for Zimbra 9 except the Modern UI code and components in the Network Edition that are closed source. Zimbra 9 binaries are only available via a Network Edition license. In summary, there are two changes in Zimbra 9 regarding Open Source. First, the Modern UI uses a commercial license (similar to Network Edition components). Second, Zimbra 9 open source binaries are not being provided.
A: Customers with a valid Zimbra 9 license are allowed access to the Modern UI code. Their sales representative can coordinate access to the source code. These customers can also submit changes and contributions for this code.
A: Commercial offerings are provided by companies who sell licenses for the use of their software. Open Source systems are released under a license in which the copyright holder grants users the rights to change and distribute the software. These open source systems are typically overseen by a community of developers who contribute modifications to improve the product.
A: Yes. Zimbra 8.8.15 remains an option for governments who require Open Source, data sovereignty, privacy, security and customizations to meet local requirements. Zimbra 9 is also an open source option, excluding the Modern UI and Network Edition components (similar to Zimbra 8.8.15 Network Edition components, ZCO, etc.). Zimbra 9 is an option where security, privacy and data sovereignty are fundamental requirements.
A: Yes. There is no change in the code from something which was previously open source to something that is not. The Modern UI is simply an additional component that has been added in much the same way as adding a new NE component. Under data sovereignty, data is subject to the laws within the nation under which it is collected. Many countries have passed various laws around control and storage of data. Zimbra is committed to adhering to those security and privacy laws, e.g., GDPR, CCPA and others.
A: Yes. There is no change to the code contribution process. Anyone with access to the source code can submit changes and contributions. Please see the Zimbra Contribution Agreement (Zimbra.com/legal), which has not changed.
I'm a long term Zimbra user for my personal stuff. With the new Zimbra 9 release a couple days ago Zimbra Inc has made it clear they no longer want to be in business as they are going closed source and not offering a free option.
After checking some prerequisites, you will be asked to accept the license agreement. Note that while Zimbra OSE is open source, it is not GPL. The link the script displays allows you to read the terms. If you decide not to install, leave the default reply as N and press Enter. Otherwise type Y and press Enter to continue. (At any time while running the install script, to accept the default answer shown in brackets, you may simply press Enter.)
Once missing packages are installed, start the installer again. Zimbra will continue its installation. Accept all the defaults, with the possible exception of the zimbra-snmp package if you have no use for SNMP monitoring.
By default, no administrative password is set. To set a password, enter 6 to display the zimbra-store menu, then 4 to type a new password at the prompt. Enter r to return to the main menu. For DNS, enter the zimbra-dnscache menu, then change the Master DNS IP addresses and return to the main menu.

The Zimbra email and collaboration suitewill change its open source policy. This post from theZeta Alliance notes the changes for Zimbra 9. "John E. explainedthat Zimbra 9 introduces a change to Synacor's open source policy forZimbra. Starting with Zimbra 9, a binary version of Zimbra 9 will no longerbe released to the community and will instead only be made available toZimbra Network Edition customers. There are currently no plans to releasethe source code for Zimbra 9 to the community. Zimbra 8.8.15 will remainopen source for the community and continue to be supported for theremainder of its lifecycle through December, 31, 2024 ( -... lifecycle/). Version 8.8.15 will also continue to receive patchesduring this time frame. John E. described this new model for Zimbra 9 as"open core" where the open source products on which Zimbra is built willcontinue to be freely available, but the Zimbra 9 product itself will notbe open source."

I liked Zimbra for its Zimbra Desktop (last release in 2017, officialy no longer supported since 2019-10-01).
It had some issues (its support for html emails was far from perfect), but I found its offline mode and searching capabilities far better than in Outlook.
My path to paying customer for Network Edition was through their free and open source edition.
If there was no free edition, we probably would never give it a try and settled on a different solution.
How many future customers are they going to loose because of this decission?

It's a purely proprietary model; it's built on top of open source software, but that's a really ridiculous stretch to call it 'open core' based on that... a stretch someone would only attempt to capture some perceived marketing benefit of the term 'open core' (little that there is to be captured).
Should we call Oracle's database product 'open core' because it runs on GNU/Linux and contains some amount of open source software? I think not :-)
Maybe it's sources only for the public going forward? Posted Apr 21, 2020 0:22 UTC (Tue) by jeffcook (subscriber, #119964) [Link]
fwiw, I interpret the comment to mean that yes, they intend to adopt a Red Hat-style model where Zimbra will only provide the applicable source code to licensees, thus no plans to release to "the community". It sounds like some new proprietary components will also be integrated.

Red Hat acquired CentOS essentially and several CentOS folks are full time employees of Red Hat now. So how CentOS gets released these days is that Red Hat releases RHEL and publishes the source to git.centos.org and CentOS team takes it from there to produce the binaries under a different brand.
>they intend to adopt a Red Hat-style model where Zimbra will only provide the applicable source code to licensees
This isn't correct. Red Hat has always published the source code in the form of SRPMS publicly. What Red Hat has restricted in RHEL *binaries*. What Zimbra is doing seems to be more like grsecurity assuming they intend to distribute source code at all.

Both the chat server and client have been developed by Zextras to guarantee the highest integration possible with your Zimbra server.More information about this can be found on the dedicated Zextras Chat zimbra.org entry.
Zimbra is an open-source email, calendaring, and collaboration software suite developed by Synacor, Inc. It comes with a shell script that automatically installs and configures all necessary mail server components on your Linux server, thus eliminating manual installation and configuration. With Zimbra, you can easily create unlimited mailboxes and unlimited mail domains in a web-based admin panel. Email accounts can be managed in MariaDB or OpenLDAP. The following is a list of open-source software that will be automatically installed and configured by Zimbra.
Other VPS providers like DigitalOcean blocks port 25. DigitalOcean would not unblock port 25, so you will need to set up SMTP relay to bypass blocking, which can cost you additional money. If you use Vultr VPS, then port 25 is blocked by default. They can unblock it if you open a support ticket, but they may block it again at any time if they decide your email sending activity is not allowed. Vultr actually may re-block it if you use their servers to send newsletters.
Avoid using the zmcontrol restart command whenever you can, because it will generate many report emails to the admin account. Every email will invoke ClamAV for virus-scanning. ClamAV is a resource hog. If you need to start/stop an individual Zimbra service, use the specific tools to complete the task .
The software consists of both client and server components, and at one time also offered a desktop email client, called Zimbra Desktop. Two versions of Zimbra are available: an open-source version, and a commercially supported version ("Network Edition") with closed-source components such as a proprietary Messaging Application Programming Interface connector to Outlook for calendar and contact synchronization.[9]
The Zimbra Server uses several open source projects (see the section, Included open source projects). It exposes a SOAP application programming interface to all its functionality and is also an IMAP and POP3 server. The server runs on many Linux distributions.[13] On other, non-Linux operating systems it can be run using a virtual machine and using container technology. It supports CalDAV, CardDAV and SMTP for messaging, LDAP for directory services, and Microsoft Active Directory (AD). Zimbra uses Postfix for its MTA functionality. It includes technology from ClamAV, SpamAssassin and DSPAM for anti-malware features and S/MIME for email signing and encryption. OS X Server support was dropped with version ZCS 7.0.
