Kerio Technologies announced version 6.5 of the Kerio MailServer -- 2 years in the making -- yesterday. We talked about version 6 recently, but this is their largest update yet and clearly shows their readiness to take a bite out of the Microsoft Exchange market. With version 6.5, Kerio is providing the groupware platform and tools needed to completely replace Exchange within a collaboration-centric organization.
The release is compatible with both server and workstation flavors of OS X with full support for Leopard, in addition to being fully Microsoft certified for Vista and Redhat certified for Linux compatibility. 6.5 also includes enhanced support for Entourage 2008, making full use of message flags and "out of office" messages which are synced on both mobile and workstation clients.
The biggest change of interest to Mac users is the addition of CalDAV support. Kerio users can look up information, share and subscribe to calendars and achieve 2-way sync whether they're on a Mac, an iPhone, a Palm or Windows Mobile handheld, a PC ... you get the idea. The server can provide a bridge between open and proprietary standards, making sure that you see the same data everywhere and allowing for smooth cross-platform interoperability.
The other major improvement, definitely of interest to users in multi-platform environments, is an upgrade to the Outlook Connector with a complete rewrite of its underlying database structure. It allows for easy data access, online and offline, with current and older versions of Outlook. And its full-text search capabilities search across messages, contacts and calendar events with support for Google Desktop search.
Not surprisingly, a release this big resulted in a pricing change. The standard package (10 users) now starts at $499 and adding additional users costs $20 per user. A version with integrated McAfee Anti-Virus for bi-directional scanning of all email starts at $599 and additional users are $24 each. Both versions include anti-spam, user management with authentication against Active Directory and Open Directory. Visit Kerio for more information.
Update: The US Apple Store is now carrying a base server (10 user) license and install media for Kerio MailServer with McAfee.
