We are currently looking into Zimbra, looking to roll it out with our company over the next 3 weeks.
I'm currently working with the IT team testing etc (and loving it)
Right now we are running Community Edition on Fedora Core 5
We have a trial license for a Network Trial running on OpenSuSE, however I read that as of ZCS version 5 OpenSuSE will no longer be supported.
What OS is the recommended. We don't particularly want to pay for Red Hat - we've stuck with CentOS for all our current servers. What is the recommended OS for Zimbra?
