ZCS network edition on other than RHEL 4 ?

[msentissi]

Hello

I was wondering if I need RHEL 4 for every server I install the different components of ZCS Network Edition.
I want to setup a multi server environment and obviously, I want to save on the licenses from RH. I would like to use the RHEL on the message store only ?

anybody tried something else (free) for the MTA or LDAP component ?

Thanks

You can use CentOS 4.x, it's binary compatible with RHEL and it's free - you can get it at www.centos.org

But you won't get support from the Zimbra team (unfortunately).
