Zimbra

Zimbra’s open source roots have always been of great importance to both the company and the Zimbra Collaboration Suite (ZCS).  When we set out to build a new collaboration system over five years ago, we wanted to bring a fresh perspective to the market, and a big part of that was our commitment to being open source.  We understood sharing ideas within the open source community keeps you a one step ahead of competitors by iterating faster to give users what they want.  A great example demonstrating how the community has flourished is the Zimlet development program.

Zimlets are simple but powerful extensions of ZCS that connect users’ email, calendar, and contacts with any number of outside services (for a couple of recent examples see Alfresco and Peru and TripIt).  Zimlet development growth in the community has been strong and steady, and we are excited to continue supporting the community’s work by providing a place where developers can feature the best of their integrations to share with other Zimbra users.   So, today we are launching an updated Zimlet Gallery where you can pick and choose from many handy new ZCS extensions.

At the same time, we also love seeing our Yahoo! friends continue to embrace openness as part of the Yahoo! Open Strategy. In addition to this announcement today, a number of our Yahoo! brethren are extending their platforms to become more open. Today, Yahoo! Mail is introducing applications which enable people to make online payments, access personal photos and more easily send large files directly from their inbox. In addition, My Yahoo! is adding even more third-party applications, driving enhanced personal productivity for users directly from their My Yahoo! start page. You can read more about the Mail and My Yahoo! updates on the Yodel and YDN blogs.

As part of the Zimlet Gallery launch today, we’d like to introduce you to a few new third-party Zimlets, including:

Xythos Zimlet - The Xythos Zimlet allows you to drag and drop email messages and file attachments directly into Xythos’ Enterprise Document Management System.  Secure document management is popular in the enterprise and universities; integration in email is key for ubiquitous adoption.

Processmaker Zimlet - The Processmaker Zimlet helps streamline workflows, like time-off requests, all within Zimbra email (see above).  This Zimlet is already becoming popular and is being deployed at Access America Transport and Ministerio de Vivienda by our Zimbra Partners.

In addition, Zimbra developers have created a handful of new Zimlets, including:

Place Sticky Notes on Email - The new Sticky Notes Zimlet allows you to attach and tag emails with “notes.” One can leave comments, reminders, additional info about the email and more. And Zimbra’s powerful search can search through emails based on the contents of the tags/notes attached to the email.

Email Highlighter - The Colored Emails Zimlet allows you to apply personally assigned colors to emails from specific senders such as a family member, your boss, etc. You can identify senders by color, but you can also create colored emails through tags, making it easier to prioritize any inbox.

Save Email as Documents - With one click, the Email-2-Doc Zimlet lets you save an important email as a Zimbra Document; it will automatically save any attachments as links in the Document as well. The email can then be edited and shared with others.

At Zimbra we’re always trying to provide our community with the most efficient tools for organizing email, address books, calendars and web documents, so it’s only natural that we look to work with other with companies who are as enthusiastic about streamlined processes as we are, and share the same commitment to open standards.

One of the latest things you can now do with Zimbra is integrate with TripIt – an innovative service that organizes and shares your travel itinerary. With TripIt, users simply email their booked travel plans to TripIt, and the service will create a master travel itinerary plan. Users may then access or share this itinerary online, via their mobile device, or from their personal calendar.

This is where we step in. Because Zimbra is an open platform, users of TripIt can instantly access flight times, hotel arrivals, and much more from the convenience of their own Zimbra calendar automatically.  The integration is especially useful in business settings, as Zimbra’s shareable schedule options and synched group calendars allow employees to view their own work-related travel itinerary alongside their co-workers’ in a shared Zimbra calendar. This way, all are kept in the loop regarding everyone’s travel whereabouts at work.

This integration also takes advantage of a number of open standards that are supported by Zimbra and TripIt including email and iCal.  Here’s how you can get TripIt integration within your Zimbra account:

1.   Go to TripIt.com and create an account
2.   When you receive an email from your travel company, forward it to plans@tripit.com
3.   Go to TripIt and find the iCal feed URL and find the URL to subscribe to your calendar
4.   Go back to Zimbra and create a new calendar called “My Trips” or whatever you prefer to call it
5.   Paste in the iCal URL after you select sync with external cal
6.   Right click refresh and your trip calendar should appear!

It may sound odd offering more Zimbra installation advice since there is a lot on the subject in other blogs, our documents, wiki and Forums. In fact, some quick research surfaced over 1.4 million hits for Zimbra server install on the web and 36,000 on the Zimbra site alone.

But we are also fortunate to have more new Zimbra users than ever, and after helping some trial customers recently, it was a good reminder a few simple tips can help cut through some noise and avoid time-consuming snags once you start the install process. So without further ado here are the top 6 common pre-requisites to consider when preparing for your Zimbra installation:

1. Firewall
Servers have firewalls configured once the operating systems are installed for security purposes. Our recommendation is to temporarily disable the firewall on the system during a single and multi-server Zimbra installation. An alternative would be to refer to our installation guide to get a list of ports (see Table 1) used by the application and make sure the ports are open prior to installation.

2. DNS setup
All Zimbra configurations store hostnames. We do not have save any IP address information in our configuration. The advantage is this allows an administrator to change IP address (more likely) on the Zimbra system without having to perform any application changes.

This scenario means that all the hostnames to be used in a Zimbra installation have to be defined in DNS. Both A and Mx records for the hostnames and email domains need to be defined and verified prior to beginning your installation.

One other thing to consider is split DNS configuration if you are dealing with servers separated by a firewall.

3. Use of Fully Qualified Hostnames (FQDN)
It is crucial to use a Fully Qualified hostname during the Zimbra configuration. For example, you should enter server1.domain.com instead of server1. This avoids incorrect DNS address lookups and ensures that the client would be connecting to the right application.

4. Port Conflicts
Standard server configuration comes with support for numerous services like POP, IMAP and HTTP (see Table 1). These services are also installed with the Zimbra Network Edition. Therefore, you want to make sure you disable all these services prior to installation. The Zimbra installation scripts will check for any of these port conflicts and notify you to turn these services off before continuing.

5. Libraries and additional packages
Zimbra’s rich feature sets are dependent on additional packages being installed on the system. These packages vary between Linux and Mac Operating system. The Zimbra installation script does perform checks to verify all the dependencies have been met, but going through the System Requirements documentation (available on the Zimbra website) before will save you some time.

STORAGE CALCULATION EXAMPLE
(Based on ‘Mailbox Usage of 200 MB’ and 500 users)

+ User Data: 500 users with 200 MB = 100 GB user data
+ MySQL data: 5% of 100 GB (User Data): 5 GB
+ Zimbra binaries: 10 GB
+ Zimbra logs: 20 GB
+ Zimbra indexes: 25% of 100GB (User Data) = 25 GB

SUBTOTAL: 100 + 5 + 10 + 20 + 25 = 160 GB
Backups: 160 % of Subtotal: 160 * 160% = 256 GB for backups
TOTAL: 160 + 256 = 416 GB

6. Sizing
Storage sizing is important for an excellent performing Zimbra application (see example). If you are doing a Network Edition trial you should contact the Zimbra technical team for sizing information for storage including number of disks, which Raid level to use, and the size of the drives to use. Configuration of the Zimbra store volume is important in satisfying the application IO requirements.

Remember, it’s also a good idea to review the Zimbra Quick Installation Guide where you can find this information and many more good tips.

One of the great things about being an open source company is that we have a passionate community that goes beyond the boundaries of any one location (Zimbra HQ, for example), with community members that participate and contribute from all over the globe.  We saw this early on with the help the community gave us for international translations,  and several of our early partners hailed from as far as South Africa, Brazil and Germany.

So in December when the Ministerio de Vivienda - the  Ministry of Housing in Lima, Peru - began looking for new options to replace their expensive proprietary software with lower-cost, open source alternatives, it came as no surprise that the open source community eventually led them to Software Libre Andino, a Zimbra / Red Hat distributor in Peru who helped replace their outdated systems with modern ones, including Zimbra for collaboration and Alfresco for document management.

The Ministerio de Vivienda, which is responsible for all the housing, construction and sewer systems in Peru, has a mission to improve access to adequate housing and basic services to all the citizens of Peru. Saving the government money is definitely one reason for the switch to Zimbra, but another important factor in their decision to deploy open source solutions is they found that open platforms allow their users to easily integrate and build new solutions on top of this foundation.

In this case they were able to deploy the Alfresco Zimlet created by Zimbra community members and allow a simple way for employees to store documents that are attached in email on the Alfresco server, and in turn select documents from the Alfresco server and attach them to a Zimbra email. Simple, inuitive integrations like these make it easy for government agencies or companies to invest in multiple open source products to meet their needs, instead of choosing proprietary options.

We love to hear stories of how Zimbra and open source technologies travel the globe – if you have any stories you want to share, drop us a line.

Some may have heard recently we are putting more emphasis on developing our Zimbra partner channels.  We are fortunate to already have more than 700 partners, including Hosting Service Providers, VARs and SIs who are doing great work; we plan on growing our program globally with more partners and new tools for them (stay tuned, more to come here).

We have kicked off the extended program internally and it’s already beginning to bear fruit.  The Zimbra EMEA team recently attended Red Hat’s EMEA Partner Summit in Malta and was among the honorees for Partner of the Year.  Red Hat and Zimbra have been working more closely together over the last several months; it’s a great value proposition for customers who prefer working closely with one vendor for an integrated application-OS solution.  We’ve had several recent wins together including one of the largest government organizations in the Middle East and in Latin America.

Here is Red Hat’s news summary from the EMEA Partner Summit.   Also below is a snap from the awards evening.  Pictured: Werner Knoblich, VP & GM for Red Hat EMEA; Lars Ronning, GM Zimbra EMEA; Gloria Coviello, Zimbra Director EMEA Sales; Petra Heinrich, Director of Partners & Alliances for Red Hat EMEA.  Wonder who played the trick on us with the logo.

Few things get our community excited like a major release version of the Zimbra Collaboration Suite. Today marks availability of the first GnR preview: ZCS 6.0 Beta 1 Open Source Edition. Admins and developers can find it over on the downloads page, for the less technically inclined we’ll also have a new hosted demo up shortly.

Some feature highlights:

» A new horizontal ‘three panel’ view with the message on the right.

» There are now tabs for individual messages as well as the compose page.

» Document & Briefcase access from the standard HTML client.

» Share management & discovery UI that lets you see all shares (email, contacts, calendar, tasks, docs, etc) at a glance. Join a distribution list late? Find all existing shares with the group.

» The ability to run existing email filters over the contents of a folder.

» Did you get it? Know instantly, as read receipts have been implemented in the web-client.

» Improved calendar resource auto-accept/decline conflict handling.

» Calendar fisheye view - previously in Zimbra Desktop, now in ZCS.

  » Auto-updating RSS feeds & ICS event URLs on a configurable schedule.

  » Per-user blacklists & whitelists are exposed in the revamped mail preferences area.

» ‘Published’ Zimlets management for end users in options. (Zimlets themselves can now define a new application or preferences tab.)

» Mobile web-client overhauls: Including a special mini logon page, better appointment creation, and six new variants based on device type and connection speed.

» Auto-complete from shared address books; and recently used contacts are presented first.

» Configurable spell check on every send.

» On-behalf-of aka sendAs option on compose in shared folders/relationship accounts.

» Appointment list view & refined print layouts.

» Full featured detached message view for the advanced AJAX client.

» Attach files during mail compose directly from the briefcase; in the briefcase UI you can now send as attachments or links.

» Pressure-based scrolling of folder and message list (within the same page).

» OpenLDAP now allows for some on-the-fly configuration changes with zmlocalconfig via a cn=config backend instead of slapd.conf text files for preservation across upgrades.

» GALsync accounts via datasource contact folders with sorting, browsing, and enhanced client usability.

» MySQL as the logger DB has been removed, in favor of more zmstat service implementation mixed with SQLite & RRD for the new logger service.

» Role based delegated permissions on every individual feature. Now you can create distribution list managers, while HSP’s can give someone permission to manage multiple domains from one login. (Available in both network and open source editions - the network edition will include easy admin console configuration.)

There are just too many enhancements to list here so we could only cover a few; check out the beta on a test server, then let us know what you think below or over in the Community Forums. Release notes are here. (Note: We advise against upgrading if using the Posix/Samba add-ons, the process will be documented shortly.) This is the first release of several in our testing cycle; general availability of ZCS 6.0 is targeted for the summer.

[Update: Please note the original post date of April 1st –we’re just kidding– enjoy! ] 

Zimbra leads the world in open source, next-generation messaging and collaboration software for Linux and Mac OS X servers. In fact, we recently passed the 40 million paid mailbox milestone. As we have grown, the question often asked is: “When will Zimbra extend its platform support to a given operating system?” Given the success of Zimbra Desktop on Linux, Mac, and Windows - we felt that a server version for Windows as was the next logical choice.

Obviously there are several hurdles going from a Linux environment to Windows, all of the third party applications we rely on need to have freely available cross-platform versions. We’ve partnered with OpenLDAP team, who have stepped up to provide an compatibility patch for a Microsoft Active Directory emulation mode. Combined with a new mail transfer agent written from the ground up, we’re pleased to bring you: Zimbra Collaboration Suite for Microsoft Windows Server 2008.

This isn’t the first time we’ve switched a package in favor of our own custom code - in Zimbra Desktop Beta 3 we threw out JavaMail and wrote a brand-new robust IMAP/POP client-engine from scratch. Replacing Postfix has been the major hurdle for a while now; the engineering team knew that it would be a daunting task.

I already do a lot of my dev work in Eclipse & IntelliJ on Windows. Previously we put PowerShell wrappers around our command line tools to assist more advanced admins. Now we’ve utilized MSI technology to provide the easiest install of a mail server ever. — Anand Palaniswamy, Server Team Lead

This extends Zimbra’s reach of services to the most widely deployed operating systems in the world - theoretically any Windows product; though XP, Vista and 7 will not be officially supported on the Network Edition since they don’t have the same long-term backing by Microsoft development teams. Editions tested by our quality assurance group cover the major versions of Windows Server 2008 including Standard, Enterprise, Datacenter, HPC (high-performance computing cluster), Web Server, Small Business, Essential Business, and Foundation Server adaptations; in both x86 & x86_64-bit variants. We hope that the community will step up to cover Itanium based processors.

For the future, the server team is working to integrate Zimbra’s Hierarchical Storage Management (HSM) with Windows Storage Server, for moving messages and attachments from a primary to a secondary volume based on the age of the message; which lets you to store less frequently accessed data on cheaper disks. Of note, the updates to junctions, reparse points, and symbolic links in recent NTFS versions allows us to do single-instance-storage as well.

We’re playing with .NET access for our SOAP interfaces in the labs. It’s potential is very impressive. — Kevin Henrikson, UI Team Lead

The compatibility with Windows will enable a large, new market for our HSP & VAR partners. To quote Jim Morrisroe, VP of the Zimbra Business Unit here at Yahoo: “It is key to delivering on our strategy and commitment to provide the best experience for users and administrators of any messaging platform in the market today. This launch enables us to sell to 2 million new small businesses and enterprises that view Microsoft server technology as integral to their success.”

ZCS version 5.0.15 for Windows platforms is now available on both the Open Source and Network Edition download pages. The Network Edition will be classified as beta until ZCS 6.0 is released - and will then contain the same product support as well as subscriptions to new releases, updates and patches. If you have any questions please contact our Windows sales team.

At Zimbra we have been very focused on measuring everything about our products’ adoption, usage and website in order to make improvements for our community and customers. We freely admit to having a burgeoning stats addiction, and though not everyone whoops it up when we barrel through the cubes shouting about the latest Yahoo! Zimbra Desktop download numbers, we think most folks will appreciate this one:

Zimbra paid mailboxes - 41 million and counting.

Crossing the 40 million mark is a big milestone and the credit lies with the growing Zimbra Community (more than 20,000 members strong) and our customers who have helped spread the word.  And our 40M paid mailboxes doesn’t even include Zimbra’s millions of open source users.
We are seeing growth in all of our products: Zimbra Collaboration Suite, Zimbra Hosted and Yahoo! Zimbra Desktop and demand for next-gen, open source solutions is strong even in this tough climate.

The primary driver in our rapid mailbox growth is our worldwide partner network. This partner network includes consumer service providers, business hosting providers, VARs and system integrators. Zimbra now has more than 675 Zimbra partners who bring their expertise and focus to the 14 industries, as well as government and education institutions, we serve. Zimbra’s partner network now includes Comcast, Eircom, HP, Frontier, Homestead, Brinkster, Red Hat and more, and these partners and others have expanded the Zimbra customer base to more than 70 countries worldwide.

The graph below shows Zimbra’s paid mailbox growth from when we began sales in 2006 to present.

In addition to strong overall mailbox momentum, we are encouraged by the growth of our customer base outside of North America. Today the majority of our new prospects (68%) are coming from Latin America, Asia and EMEA (Europe, Middle East, Africa). It is clear evidence of the power of a global open source community and the impact of new mandates for open source software. Below is a chart of Zimbra paying customers by region; all-in-all more than 60,000 organizations are using Zimbra.

Before heading back to the math grindstone, we want to share one other fun data nuggets: Zimbra Desktop is just shy of two million downloads (we’re estimating we’ll get there in a week). 

Thanks again to all Zimbra Desktop users for your support and feedback – we wouldn’t be where we are today without you; stay tuned for Desktop GA right around the corner!

We had a Mac oriented year-in-review, but some have asked “what about those of use who aren’t apple fanboys?” So as the holidays become a distant memory of nothing more than food, friends, and family; thought we’d take a 2nd moment to look back at community contributions and other happenings of 2008.

What seems like only a little while ago, we posted on our 10,000th forum member, and just two months thereafter we hit 11,000. We promise not to post stats every few thousand registrations, but these are just so staggering:

• Sept 2005: We started the forums.
• Nov  2006:  5k Members
• Sept 2007: 10K Members
• Nov  2007: 11K Members
• Dec  2008: 20K Members

In simple math, that’s almost double (x1.7) our growth rate over the past year. In that same time period the amount of posts and threads have also skyrocketed.

The fact that so many active members stick around to contribute and help their brethren on topics ranging from administration to development plus everything in-between, continues to amaze, impress, and makes us proud. Zimbra is clearly about something more - giving back, enhancing, and shaping the future of communication.

Seems more of you need to subscribe to the blog though (visits vs subscriptions) but I digress - hint: There’s a box on the right

As our organization turns five, and our community three we just wanted to echo one more giant thank you. Your feedback and ideas are what keeps us pushing the limits of collaboration. We couldn’t do it without you.

Often hitting over 600 new registrations a month, and pushing close to 120,000 posts - the forums are so busy we thought we’d give you a little update, just in-case you haven’t had the opportunity to take it all in!

Here’s a bit of the highlights from the past year:

 
Going Mobile

Some excellent contributors have stepped up to make Open Source mobile synchronization for contacts, calendaring, and tasks a reality.

It’s may seem like a lot of work, and not for the faint of heart, but you can checkout the Funambol thread or find more info here. (Special thanks to Hillman, Wolfroma & Costa-101)

Want just open source push mail? You can find directions over in this wiki.

We’ve made our Java based ZimbraME client open source. Get the code from our public perforce cache, then modify & combile it for your needs. It will build and run on just about any phone that runs J2ME. You can also download one of our pre-compiled releases - including one for BlackBerry devices.

Too daring for your taste? The two mobile web-client cousins (main & mainx) are also available in complete open source and work in just about every browser. They provide excellent JSP tag lib examples for making your own portals or quick optimized client - they have all sorts of uses. (We promise more info on creating these home tab portals is coming shortly.)

 
Community Builds

We’ve added an amazing team of OpenSource Buildmasters that put out community builds for Ubuntu 8 32/64-bit (now an official release), Solaris 9 & 10, Mac OS X 10.4 PPC, OpenSUSE, and even FreeBSD - yes you didn’t misread that list.

(Dijichi2, Osmedts, and many more have done an excellent job!)
 
Mail-Clients
 

 
There’s always those that love their favorite thick-client so much we’d have to pry it from their cold dead hands. For Thunderbird fans Zindus has taken ZCS<>Thunderbird sync for personal AND shared contacts to a whole new level. (Thank you lmj!)

 

Zimbra Desktop builds have been packed with new content that you’re just going to have to read all the blog entries on Beta 5, Beta 4 & Beta 3. It’s not just about ZCS Sync anymore, ZD is here to help you connect with multiple major providers. We’re in the process of joining multiple repositories to bring it to the masses easier. Plus it’s a perfect testbed for quickly developing new themes or Zimlets without installing an entire test server. There’s even a community developed Solaris port by SivaSSKumar available here.


Tools, Extensions, & Zimlets

- Pbruna built ZimbraNotify, a Linux Toaster equivalent.

- Samba & Posix extensions now come pre-bundled.

- Deugenin developed an extension for global email footers!

Zimlets Galore: From the self backup ideas of StarXpert & Fbackup, to user-managed resource & location control from the ZWC, plus a whole slew of excellent collaboration tools - you can find a whole lot more Zimlets in the gallery. (And “Zimlet Month” is coming up fast.)

 
Other Cool Stuff

The new DnD Zimlet & FF extension allows you to to simply drag attachments from your desktop into you web-client’s mail compose window or briefcase. We plan to make this cross-browser/multi-platform using Yahoo’s BrowserPlus in the future, and in ZCS 6.0 we can alert you to new mail on your desktop - or even read your mails back to you out loud.

We’ve honed our CalDAV & free-busy interop calendaring with participation in multiple CalConnect roundtables.

The developer section of the forums is abound with stuff from an AJAX ticker on the login page, to perl access modules, and not one but two a interesting methods for individual and global read receipts.

Integrate Zimbra into your favorite browser in the form of mail/appointment notices, a toolbar, or make your daily ZCS interactions more useful with things like FF3’s new protocol handlers. Plus WebDav has so many uses that people are only starting to discover.

There’s also 1, 2, 3 reasons you have no excuse to not be backing up - more here, and we made it so simple that even users can do it. And some recent HA ideas if you’re not one for DRBD or some other favorites.

 
Forum Enhancements

The forum got a theme revamp, portable edition, and revised layouts.

Some new areas include:
* Specific product sections like Zimbra Desktop, Connector for Blackberry, and the J2ME phone client.
* A section dubbed ‘Camp Zimbra‘ for those who’ve completed official training and become ‘Alumni’.    
* Zimbra in Education gives our EDU professionals a opportunity to unite.
* An /etc lounge for general conversation.
There’s now one click access to Wiki Sandboxes - make yourself a reference guide or use it to troubleshoot.

And last but not least, we’ve increased the size of our awesome crew of volunteer moderators and regulars who give up their time to answer your admin and developer related questions everyday.

Thanks to all who visit the forums for making our community first rate!
