This is one people have asked about a lot. Starting with Zimbra Collaboration Suite 6.0, we will be providing a formal Zimlet Developer’s Guide and API Reference. The goal of this documentation is to make it easier for partners and customers to build Zimlets and to integrate with the Zimbra platform. As we’ve built this documentation, here are some of our guiding principles:

• Easy to find. Make the documentation online and “wiki-based” for easy access.
• Reduce “wondering” between versions. Maintain documentation with each ZCS release so when new major versions of ZCS are delivered (and changes are made to the APIs), people on older ZCS releases can still access their “version specific” documentation.
• Lower overhead to get started. Make developing Zimlets possible without having to download the entire product source. Of course, product source will still be available for those who want it but we want to make even advanced Zimlet tasks (for example, compiling templates) possible without needed the entire source tree.

Here are links to the new developer documentation:

Many of our partners, customers, administrators and end users have seen the Microsoft announcement regarding a roadmap to document the Outlook Personal Storage Table (.pst) file format, and have expressed their curiosity about it’s impact on Zimbra products. While it is still unknown if documentation will provide enough insight on how to really unlock the Outlook PST, we see it as the first step in providing new functionality in future versions of Zimbra Collaboration Suite and Zimbra Desktop that access the terabytes of data in PSTs.

For more than a decade, many attempts have been made to understand the Outlook file format, and products have struggled to provide PST support on platforms other than Windows. All efforts have come up short for one reason or another. As Paul Lorimer mentions in his blog post: MAPI and OOM libraries have been available to access PST content, but those libraries are available only to Microsoft programs where Outlook is installed. This dependency forces customers contemplating an OS or platform switch to include email data portability as factor in their decision.

Customers believe this is not a long-term acceptable scenario.  As a result, the software industry is in the midst of a gradual transition, moving from proprietary API and data models to open source and standards based options to prevent data lock-in and to encourage data sharing across applications.  But why haven’t companies spent more time or moved more quickly to open-up their platforms and data given the market’s trend line?

Companies have externally argued that the standards are not complete, or are in conflict with competing standards or they have just not seen the customer demand.  Internally they traditionally weigh existing revenue and investment in developing their proprietary APIs against creating & implementing open formats with greater potential reach and less well understood revenue impact. What has resulted is a string of complicated interoperability and conversion tools, with limited features and ambiguous product life cycles.

There is a lot of discussion out there about the meaning of openness, as noted in the recent Google blog, which has certainly garnered it’s share of comments (see John Grubber’s response or Matt Asay’s response). Regardless of the larger ongoing debate, historically, Microsoft has used data formats, like PST, to create application lock-in and as a wedge to drive commercial business. This only works for so long. Customer benefit has little to do with the underlying data store and more about user features.

Zimbra was built on the belief that a winning recipe is balancing an open system and support for standards with the commercial aspects of the business. Zimbra has always provided access to our core application source code and has been a huge proponent of open formats, throwing strong support behind standards like CalDAV. This platform and technology openness, as Matt Asay points out, allows vendors to focus on solving customer problems, not on the nuances and licensing (i.e. control) of underlying data.

We applaud the effort by Microsoft to help free their user’s data and feel this announcement is another piece of evidence that the need for “openness” has surpassed critical mass. We eagerly await release of the final PST documentation.

Zimbra’s massive user base means our new product releases reach farther than ever before. How far? Consider our 50 million paid mailbox count. With that comes the responsibility to make our solutions exactly what people need when it comes to shaping the future of communication.

So what are some of the top requested features included in the first release of Zimbra Collaboration Suite 6.0?

Sync your phone like never before.

We’ve added user trigger-able device wipe, server policies, and tasks to the existing MobileSync support for email, contacts, and appointments.

Arrange and personalize the interface.

Read and compose multiple messages in tabs without the need for pop-out windows using the advanced AJAX client. Widescreen? Move the reading pane to the side.

 

Presentation Framework.

Create new presentations (as well as documents and spreadsheets) from the briefcase – no need for external software to run them.

 

Calendar views. Direct CalDav connections. Streamlined contacts.

Our feature rich UI has new layouts including fisyeye and a sortable list view. Access an external ICS/CalDAV url – with adjustable automatic update polling frequencies. For the address book: Rather than pages of blanks to fill out, add only the contact fields you want.

 

Lite-client overhauls galore.

The standard HTML client now includes all our primary apps, plus the ability to drag items like it’s AJAX cousin. Using a web-browser on your mobile device? There’s multiple variants based on device type and connection speed. We’ve added appointment management functionality to the portable web-client, a simplified login page, as well as file access.

Role based administration.

Delegate. Empower distribution list managers without worrying about them accidentially changing major server settings. Even let someone add or remove members, but not create or delete existing lists – the views and ACL rights are that customizable. Hosting providers can now give one account permission to manage multiple domains or adjust class-of-service features.

 

Connect with your social world.

Zimlets now have the ability to define application or preferences tabs. So use the new Social Zimlet to manage Twitter, Facebook, or just browse Digg. Try the Discover Zimlet to visit all that Del.icio.us has to offer.

Share Management.

Join a new group? Get up to speed fast – receive and an instant email about all the available shares. Didn’t accept that invite long ago but turns out you need something? Rather than digging it up, just use the new share tool to see what you have permissions on; or have given to others.

 

Server Architecture Improvements.

A few of the powerful under-the-hood changes include a new OpenLDAP engine with the ability to make on the fly config tweaks, SQLite & RRD for logger, customizable hierarchical storage queries. Plus we’ve exposed a UI for the stats service – giving you quick insight on just about everything you can think of.

Someone on the Zimbra freenode channel recently asked: “Why skip the usual numbering scheme?” Well, we felt the above along with several hundred other groundbreaking enhancements made it worthy of a major revision number instead of a more modest 5.5 designation. Be sure to checkout read receipts, browseable company directories (global address list sync folders), on-behalf sending options, print size controls, published (self-enabled) Zimlet settings, fast on-demand/header-first sync in the Outlook connector, and the ability to run filters over existing items.

We’ll have to stop listing improvements there, but the great strides of Zimbra’s growth trajectory can ultimately be traced back to the power of our partner model and community ecosystem. While we don’t reflect Open Source Edition users in our metrics, everyone here certainly recognizes their role in making the Zimbra Server what it is today. So no matter which edition you use, our engineering team invites you to leave us some feedback on version 6.0.1 over in the forums. What features do you want to see implemented next? Let us know below, or test the nightly builds for a glimpse of aspects like pressure based page scrolling, support for the CardDav standard, and the ability to remove attachments but retain an email body; all of which are just a heartbeat away.

With thousands of votes from the Zimbra community submitted to our product management database, and tens of thousands of hours logged by our engineering team, we are excited to officially announce Zimbra Collaboration Suite 6.0.

ZCS 6.0 is chock full of everything you asked for – because we made sure to check off the hit list of top requests. Some of the highlights include improved delegation and share management, increased productivity with three-pane email view, read receipts, remote wipe for mobile devices, and more. Our goal was also to make ZCS 6.0 the most flexible product yet, so we’ve also made it easier than ever to integrate 3^rd party software. You can learn more about the new features in 6.0 later today in a deep-dive blog post.

But that’s not the only recent milestone: Did you ever wonder what Zimbra and South Africa have in common? No it’s not our love for South African Hip Hop or Kwaito … it is that Zimbra just bested their population of 49.3 million because today, we have surpassed the 50,000,000th paid mailbox mark. Meaning if all Zimbra users made up their own country they would be the 25^th most populous in the world, edging up on Italy (Pasta anyone?). It’s amazing that we were able to gain ten million paid mailboxes just six months after reaching 40 million. Those 50 million accounts are spread across over 100,000 organizations that are now using Zimbra throughout the globe. That leap can only be attributed to our wonderful collection of partners and developers who continually remind us what people need so we can deliver the best collaboration product on the market.

We’ve been lucky to have the opportunity to work with a wide range of customers – from enterprises such as Mediacom and WebMD, to new government organizations including The Drug Enforcement Administration (DEA), Greece’s Ministry of Foreign Affairs, and Oman’s Ministry of Health; to educational institutions like Swarthmore College, Ecole Polytechnique de Montreal, and Savannah College of Art and Design.

As a long-time Zimbra developer and employee, I’ve spent countless hours each week using Zimbra email.  I love the overall experience, especially because I have been able to tailor it to my personal style using Zimlets.  They are easy to create and over time I have built quite a few.  So without further ado, the following is the first of a 5 post series featuring new Zimlets which I think are incredibly useful and empower Zimbra users.

Zimlet 1: Attach Emails

Every so often I miss the ability to easily to attach an earlier email while composing an new email message.  This Zimlet does just that, it adds an “Attach Email” tab in the Attachments dialog in Mail Compose. Once you click on the Email tab you can search for emails that you want to attach or just scroll the list. You can even ‘browse’ for emails by clicking on the folder tree.  Finally, something I really like is with any of these methods you can also select multiple emails and attach them simultaneously.

Here is how it works… assume you are composing or replying to an email and now you want to attach some earlier email…

1. Click on the Add Attachment Button

2. Click on the Attach Mail tab

3. Search or browse for emails (in this case below I’m looking in the Sent folder)

4. Select the email(s) you want to attach – ctrl to select multiple.

5. Click Attach button

You can repeat these steps again if you want for more emails or other attachment types.

Note – you need ZCS 5.0.15 and above or 6.x to use this Zimlet.

Next post… Ignoring Conversations.

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.

Do you have a good tip to share? Feel free to add a comment!

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.  ;)
