“This article explains how to install Zimbra Collaboration Suite
7 (ZCS) on CentOS 5.x (64Bit). Zimbra is a collaboration suite very
widely used in the world. Users can share folders, contacts,
schedules and other things, using a very rich web interface.
“One important note is that we’re using CentOS 5 64bits, that is
not oficially supported by Zimbra team (only RHEL and SUSE are).
But CentOS works fine with Zimbra.”
