Red Hat expands open source stack

Linux distributor Red Hat bulked up its open source enterprise server offering on Thursday by adding support for another open source mail product.

Open source collaboration toolset Open-Xchange Server 5, which until now was only available on Novell's SuSE Linux Enterprise Server, will now be supported on Red Hat Enterprise Server 4.

Red Hat already offers a number of open source mail products with its enterprise version of Linux including the Cyrus mail server and the SpamAssassin spam filter.

Open-Xchange Server offers additional features including calendaring, contacts and a connector to the Microsoft Outlook mail client, allowing companies to migrate from Microsoft Exchange to Open-Xchange without needing to change their mail client.

Netline, the company behind the Open-Xchange Server, said in April that it plans to provide commercial support for its product on Mac OS X and Solaris later this year.
