Installing Zimbra Email 8.6 on CentOS 7

If you want to additionally expose the web admin console:
firewall-cmd --zone=public --add-port=7071/tcp --permanent firewall-cmd --reloadhttps://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 ?

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?

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.

Despite all its problems, some of us like Outbreak -- I mean Outlook.

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

Yes, they added that over a decade ago now, I think.

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

I always liked Zimbra and could never understand why people would use Exchange over it. The web interface was amazing in 2010 when I was running it personally.

Even more dramatic going back to like 2007 or earlier.

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?
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 TCO2FA 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 certificatesFor 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 certificatesCustomers 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.
