Installing Zimbra Email 8.6 on CentOS 7


  • Service Provider

    Zimbra is possibly the most popular free and open source enterprise email and collaboration suite. It is mature and advanced and has, at times, been part of both the Yahoo! and VMware families. The suite has remained open source since the beginning and was one of the earliest drivers of enterprise AJAZ interface designs. Development of the suite is active and Zimbra 8.6 is the most recent release. While a major product suite, installation of Zimbra is relatively straightforward.

    At this time Zimbra 8.6 officially supports CentOS (and RHEL) 7 and CentOS (and RHEL) 6, Ubuntu 14.04 and Ubuntu 12.04 (partially.) Support for SLES is being discontinued. Unlike in the past (around Zimbra 5 era) CentOS support is official and is not a technicality riding on RHEL's coattails. CentOS 7 represents the recommended installation target for Zimbra for many reasons, maturity and most up to date supported platform being key.

    The Zimbra installer handles many of our tasks for us, there is little that needs to be done to prepare our environment although a few steps are needed. We will start by creating a minimal CentOS 7 server install (in my example, by cloning my minimal template on a Scale HC3 cluster.)

    clone centos on scale hc3

    I use 1GB as a default, but for a large email platform likely you will want a minimum of 2GB of RAM and quite likely rather a bit more. I'll use 4GB in this example. If you have run Zimbra on CentOS 7, you will likely notice that 2GB is the absolute minimum for an idle Zimbra system.

    add memory Scale HC3

    Adding an additional block device will be common for a production installation. Putting your email store onto its own XFS block device would be advised. For a lab or test installation this would not be necessary at all. But for production, it is likely that you will want an XFS filesystem on an LVM logical volume. As this is email, it is common to have 20GB - 100GB per mailbox, so this can scale up quickly.

    add a block device on Scale HC3

    Now we can log in and run our installation. Take note that in our one step we need to manually edit our /etc/hosts file. We need that entry to match our hostname or the Zimbra installer will halt and make you fix it and run the installation program again:

    yum -y install perl wget nmap-ncat perl-core unzip firewalld net-tools
    cd /tmp
    wget https://files.zimbra.com/downloads/8.6.0_GA/zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz
    tar -xzvf zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz
    cd zcs-8.6.0_GA_1153.RHEL7_64.2014121515111
    vi /etc/hosts #Add IP and FQDN of the local host, must match hostname
    firewall-cmd --zone=public --add-port=8443/tcp --permanent
    firewall-cmd --reload
    ./install.sh 
    

    And that is it. If all went well, you can point a web browser to https://your.fqnd.com:8443/ and you will log in to your email desktop!

    The Zimbra installer is a bit of a beast. It does a ton of validations and installations for us. Thankfully it uses RPM under the hood so does not violate good practices on CentOS. For those wanting a little hand holding, here is the output of the installer:

    If it is not clear from the print out or from the menu, the reason that the system stops you is to force you to set the admin password. The menu option for this is: 7, 4, r, a.

    If you want to additionally expose the web admin console:

    firewall-cmd --zone=public --add-port=7071/tcp --permanent
    firewall-cmd --reload
    

    https://mail.your.domain:7071/

    Once you have logged into the admin console, the system wizard will step you through the installation of a certificate which will allow the MTA (Postfix) to start and the MTA cannot start error on the screen will clear.

    My test install, even without DNA entries or MX entries was able to successfully send email out immediately and successfully to external systems.



  • As nice as the platform is, this comes back to why would you host email in-house?

    Also is their Open Source system compatible with Outlok & ActiveSync ?


  • Service Provider

    @dafyre said:

    Yes. Outlook via IMAP or ActiveSync. AS is not included but requires an external package, available from Zimbra.

    But this often comes down to... why would you use Outlook when there are superior options for free?

    @dafyre said:

    Zimbra is where on premises email has a shot at being viable. Unlike on premises Exchange which incurs nearly all the cost of hosting plus loads of complexity, Zimbra removes the OS licensing cost, the per user licensing cost, the email server licensing cost, the AV and spam product licensing cost (it is included) and all of the cost and effort of managing those things which dramatically changed the equation.

    For a normal shop, things like Rackspace hosted email still make way more sense, but for people on the fence or with special needs that make on premises email a need, Zimbra is far more useful than Exchange.

    I see that Zimbra has their own email client as well. I may have to kick this around a little bit.

    It was 2003 when eWeek ran their article that the Zimbra web client had surpassed the Outlook fat client in looks and functionality. They did a test and the average user could not determine which was the web client and which was the fat one but were more likely to pick Zimbra as the advanced one! Thirteen years ago!



  • @scottalanmiller - all installed, had to open port for admin panel and had to install systat as a prereq, very impressed with the built in features. do you know if opensource edition has a limit on domains?

    Open source has no limits. Limits are inherently not possibly with open source because you'd just modify the source to remove the limits 🙂

    Zimbra's web GUI is amazing. I remember when we looked at going Zimbra over Exchange 2010. I had built a test VM to give it a proof of concept with a different e-mail domain. Though people liked it, they couldn't accept the death of Outlook. I was shot down by management and forced to go to Exchange 2010. There's no doubt it was great experience rolling out Exchange 2010 for the organization, but I sometimes wonder how things would be different to this day had we gone with Zimbra.

    You should have just connected Outlook to Zimbra and not even mentioned that it wasn't Exchange 🙂

    Their Outlook connector at the time didn't seem to sync properly with both Outlook and mobile devices. It didn't, at least, during my demo with the CEO. 😞



  • What's new in the latest version?

    @StrongBad said in Installing Zimbra Email 8.6 on CentOS 7:

    What's new in the latest version?

    Mostly stuff for the commercial customers:

    Focusing on security and privacy while continuing our dedication to our open source community

    BUFFALO – July 13, 2016 – Synacor, Inc. (Nasdaq:SYNC), the trusted multiscreen technology and monetization partner for video, internet and communications providers, device manufacturers and enterprises, today announced the latest product release—Zimbra Collaboration 8.7—by Zimbra, the world’s leading open source-based email and collaboration software. Zimbra Collaboration 8.7 is specifically enhanced for global enterprises and service providers, including Two-Factor Authentication (2FA), a new Zimbra Packaging System, SSL Server Name Identification (SNI), and Zimbra Postscreen, and all delivering a low total cost of ownership (TCO).
    For Enterprise Customers, Zimbra 8.7 delivers enhanced security and a lower TCO

    2FA offers enterprises enhanced user-account security
    Postscreen offers enterprise customers enhanced anti-spam capabilities and reduced infrastructure overhead required for SMTP processes
    SSL SNI allows enterprises to cost-effectively deliver domain specific SSL certificates
    

    For Service Providers, Zimbra 8.7 delivers streamlined deployment, product differentiation, and reduced TCO

    New packaging repository improves the ability for service providers to patch third-party packages without having to upgrade an entire installation
    2FA offers service providers competitive differentiation in the marketplace
    Postscreen offers service providers enhanced anti-spam capabilities and reduced infrastructure overhead required for SMTP processes
    SSL SNI allows service providers to cost-effectively deliver domain specific SSL certificates
    

    Customers already upgrading to Zimbra 8.7

    Customers are eager to upgrade and take advantage of the 2600+ enhancements and bug-fixes delivered in 8.7
    New packaging repository gives customers rapid and painless patching of third-party packages
    
    “Zimbra Collaboration 8.7, the highly anticipated new Release of Zimbra, is here. The focus of our latest release is security, privacy and reliability specifically geared to our enterprise and service provider customers, and also continuing our dedication to our Open Source Community,”said Brent Rhymes, EVP, Enterprise Sales & Marketing, Synacor.
    
    “To help our customers and partners better meet critical security needs, Zimbra invested serious development time into a 2FA feature, as well as a new packaging system that helps in the security and administration of Zimbra Collaboration. We also are debuting postscreen functionality and SSL SNI, features that will appeal to hosting providers.”
    

    Key Enhancements offered in Zimbra Collaboration 8.7

    The security of each individual user is a prerequisite in most enterprises. Zimbra Collaboration 8.7 includes a native 2FA feature that doesn’t require a plugin at the server or user level, and works with the most well know OTP mobile applications. With 2FA, two components are required to log into an email account—something the user knows: a password, user ID, etc., and something the user possesses: a smartphone or USB-key.
    
    With the new packaging system in Zimbra Collaboration 8.7, applying security patches and Zimbra updates are easier than ever before. When a new vulnerability arises, it’s simple updating of individual Zimbra components instead of the entire Zimbra package (typically a full upgrade).
    
    Zimbra Collaboration 8.7 comes with postscreen at the MTA-level. The postscreen daemon provides additional protection against mail server overload. By keeping spambots away, postscreen leaves more SMTP server processes available for legitimate clients and delays the onset of server overload conditions.
    
    Customers and Business Service Providers (BSP) hosting multiple Zimbra domains now have official support for Multiple SSL domains on a single server (SNI) for HTTPS connections. With 8.7 it is now possible to publish multiple SSL Certificates using one single IPv4.

    Zimbra only offers it commercially. But Kopano makes a free component that you can use with Zimbra or Kopano. So ActiveSync, in theory, is free with Zimbra, just not free IN Zimbra.

    Back in the days when we were doing a Zimbra proof of concept, someone told me about Zextras. It looks like they have some very neat bolt-ons for Zimbra Open Source Edition - https://www.zextras.com/. All of the features you see are licensed based on the number of mailboxes you have.

  • Service Provider

    Zimbra was initially developed by LiquidSys, which changed their name to Zimbra, Inc. on 26 July 2005. The Zimbra Collaboration Suite was first released in 2005. The company was subsequently purchased by Yahoo on September 17, 2007, and later sold to VMware on January 12, 2010. In July 2013, it was sold by VMware to Telligent Systems which changed its name to Zimbra, Inc. in September 2013. It was then acquired by Synacor Inc on 18 August 2015.


  • Service Provider

    We've been running Zimbra since pre-Yahoo days.



  • @StuartJordan
    Zimbra has been and is still great. The one con I can think of one the OSE version does not have a built-in capability for backup...though there's a lot of scripts available. Those can also be found on their wiki or forum.

    I have also been told that they have removed the built-in chat...and the Zextras chat as well (though I'm still debating this with the vendor I am speaking with as there are still pointers regarding its availability).

    Below is the link for the comparison:
