Someone in the forums recently asked about ways to migrate individual accounts from one ZCS instance to another, so thought I'd share the enlightenment with all. Whether you are going from an on-premise install to a hosting provider, want to create handy archives of old employee accounts, or just need to duplicate mailbox contents of a user; the syntax in this article proves remarkably useful, and applies to all editions. There are a multitude of comparable RFE's on addressing this need via different approaches. (Bugzilla entries 19630, 29573, 28443 & 30163 to name a few.) Some want graphical tools to browse data and selectively migrate certain things, while others would be happy with a cross LDAP zmmailboxmove. Depending on your situation, several backup tools can take care of a large portion of your daily needs; and there are ways to do Zimbra-to-Zimbra migrations using the Network Edition's backup and restore capabilities - however they require admin abilities on both systems.… Read more »

In 2003, we founded Zimbra because we thought that existing e-mail and calendaring solutions were broken and we knew we could create something much better – that something is the Zimbra Collaboration Suite (ZCS), an Ajax-based collaboration client that integrates email, contacts, shared calendar, instant message, documents with sharing capabilities, advanced search and VoIP into a browser-based interface. We owe the thousands of members of the Zimbra community many thanks for their ongoing contributions – together, we’ve achieved great things! We’ve given customers “new and improved” mailboxes and we’ve focused on creating the best possible experience for collaboration – streamlining overflowing inboxes, organizing correspondence, and reducing the hassles of managing communication tools on the back-end. A year ago, we joined the Yahoo! family to extend Zimbra's reach, share our expertise to one of the top mail services in the world – Yahoo! Mail – and to continue to change the face of how users collaborate at school, work, and home. Yahoo! has given us the resources, including greater computing power, to continue to expand and update ZCS with new features, and support an ever-growing customer base.… Read more »

Zimbra is presenting a session on Zimlets at Yahoo's Open Hack 2008. The session starts at Noon PDT, and we'll be live blogging here. Stay tuned. Hack Day Blog - Hack Day Twitter - OpenHack Zimlet Wiki … Read more »

HackDay just kicked off, and we've seen all sorts of things go from idea to prototype in just 24 hours. This year has a twist: Not only are our engineers across the globe involved (with many making it an all-nighter) but everyone is invited to participate - even you. Open Hack 2008 takes place September 12-13th where anyone with an idea is encouraged to gather a team up, then spend a day building stuff that they think is cool. HackU (the University Hackdown) is even flying in its top ranks, with a few Zimbra customers among them (including Stanford & Georgia Tech) to join us at Yahoo! HQ in Sunnyvale, CA for rounds of coding; plus camaraderie, food, demos, awards, and good music. From our team KevinH & JohnH are also giving several presentations throughout the event.… Read more »

Hey, did you hear that Google released a browser? Yeah, and it's very cool! We might have been a bit early to call Safari the Browser war winner. Based on WebKit (KHTML), this rendering framework (that Chrome uses) has really stormed the market. If you asked us five months ago who was winning the browser war, we would easily say Firefox, with Safari as a close second. With the introduction of Chrome, a new war has started. At the start of this century, the war was about "Open-ness" and who could be more open and win the hearts of users. Now it's a war of speed, and who's faster.… Read more »

Part 1 covered Network Edition backup features, today's snips apply to all editions. First among the lesser known additions: We recently provided the possibility for a nice performance boost to some environments by adding the ability to turn on batched indexing in ZCS 5.0.3 (you can even fine tune it at the localconfig, COS, and account level). We're not talking about when you re-index an entire account here, this is a change to the index-as-received model; now new items can sit in a 'queue' (really a 'indexing deferred' flag on the mail_items table of the pertaining mboxgroup database in MySQL) to run all at once when it reaches the zimbraBatchedIndexingSize threshold, saving you from all the tiny disk thrashing. It might not be immediately apparent that this works better, but you can mention it in the forums and we'll show you the evidence to the contrary - it proves expecially useful for POP heavy or ZAD archive accounts.… Read more »
