Replace Outlook Webmail with Open Source Zarafa

“Looking for a Webmail offering that’s competitive with
Microsoft’s Outlook Web App (OWA), but available on Linux? One of
the best Outlook alternatives for Linux is Zarafa, a collaboration
platform with support options for businesses that need a robust
replacement for Exchange.

“Zarafa seamlessly integrates with your already working Linux
email server, offers all of the advantages of the Exchange OWA
platform (and more), and does so at nearly half the cost. And,
although there is a cost involved with the software, Zarafa is open
source (GPLv3). And in this article I am going to show you how to
install Zarafa on the Fedora platform (release 13 in this instance)
and integrate it with a working Postfix installation.

“If you’re looking for a guide to getting Postfix up and
running, see “Install and Configure a Postfix Mail Server.” Make
sure you have Postfix running and delivering mail before you start
the process of installing Zarafa.”
