Kerio MailServer 6.4, a groupware server for Linux, Windows and Mac OS X, was named Best Messaging Solution at the LinuxWorld Conference & Expo in San Francisco this week. The LinuxWorld Product Excellence Awards distinguish product and service innovations by LinuxWorld and NGDC exhibitors. "We've spent years researching ways of simplifying business messaging, all along being committed to the Linux platform," said Dusan Vitek, VP of Marketing at Kerio Technologies Inc. "We are honored to accept this award as a recognition of our efforts." At the LinuxWorld Expo this week, Kerio debuted its new Kerio MailServer VMware Virtual Appliance that allows IT administrators to evaluate Kerio MailServer using VMware software (server, workstation or player) or deploy Kerio MailServer on the VMware ESX Server for production use. In the recently launched version 6.4, Kerio MailServer introduced mobile email for BlackBerry and Symbian-based Nokia smartphones which build upon Kerio's existing Direct Push email for Windows Mobile and Palm phones. Kerio MailServer also lets organizations use Apple's iPhone as a mobile email, contact and calendar communicator for business messaging.
