Zimbra Collaboration Suite

This release adds support for instant messaging, tasks, online document authoring (GA), and over-the-air sync to BlackBerry, iPhone, and J2ME devices.

Support for an automated MySQL database corruption check that will send a notification to the admin. Spam training has been enhanced by allowing programmatic scanning of folders without requiring a password. Admins can get backup and restore complete notifications sent via email. .Doc and .pdf files open correctly in Zimbra Web Client. iSync will not duplicate the calendar, and iSync Connector works correctly with Mac OS X 10.4.10. Servers automatically start after a ZCS upgrade. Web-based cross-mailbox discovery is available for the optional Zimbra Archiving and Discovery module.

This is the first release in the 5.0.0 release
cycle. New features
include IM, Tasks, Standard Client autocompletion,
and keyboard
navigation. Updates have been made to migration
wizards and
apple/outlook connectors.

Secure SMTP on port 465 is enabled by default during installs or upgrades. vCard email attachments can be easily added to Address Book. The upgrade time for a large deployment was reduced. Full backups now support more than 32,000 users on a server. The Exchange and Domino migration wizards were enhanced for calendar events and aliases. Account aliases are now hidden during a GAL search. Fixes were made for time shifts between calendar events set on Treos, Outlook, and the Web client.

This release fixes a number of bugs in 4.5.2. The
impact of one bug was that incoming 8-bit messages
could be permanently corrupted when they enter the
ZCS. This has impacted several customers outside
the United States and customers anywhere
receiving mail from people outside the United
States. This major bug existed only in 4.5.2 and
is fixed in 4.5.3. The periodic issues with the
Web client failing to load in IE7 are believed to
have been fixed.
