Setup & Configure Zimbra Community Edition Server Using CENTOS

I have just setup a "clean" installation of CENTOS 7 Server on VMWare Workstation at home. I will provide access to this Server via SSH credentials. I need someone to install and configure the COMMUNITY EDITION (i.e. free edition) of the Zimbra email/groupware server AND the Z-Push "addon" (to enable Activesync functionality). I also believe that for ZImbra to function properly, a DNS "component" within CENTOS (viz. DNSMASQ) needs to be implemented/activated and configured. The new Server will ONLY be used for email/groupware. The new Zimbra Server will replace a Kerio email Server that I am currently operating on my personal domain. I use NameCheap as my DNS host and have setup the appropriate A Records and MX Records there when I implemented Kerio. I also have opened all of the necessary ports in my router to enable Kerio to operate. However, as I need access to my existing Kerio email Server until I have the new Zimbra server fully operational, I CANNOT redirect either Port 25 or Port 80 to the internal IP address of the new Zimbra Server, as they need to stay directed to the Kerio Server until then to keep my mail flowing. During the implementation and testing of the Zimbra Server, I will be able to take my Kerio email Seerver "off-line" (and do temporary Port redirects etc) for only short periods of time to ensure that my current mail flow is not interrupted for too long. I will consider the Project as finalised once (1) a test email user at the specified domain has been created on the new Zimbra Server (2) that user is able to send and receive mails both internally and externally, as well as being able to utilise the "standard functionality" of Zimbra (viz. email; calendar; tasks; notes); and (3) that user can be connected to the new Zimbra Server using the ActiveSync protocol (i.e. Z-Push) via (a) MS Outlook 2013; (b) An IOS device; and (c) An Android device.
