I'm considering strongly upgrading from OpenExchange 4.1 to Zimbra. Very little support or users for OpenExchange.
I currently have OpenExchange in production and it is critical to our business at this time. I'd like to set up a test zimbra server, so I assume it will have to have a different domain.
Our current domain is bookpros.com, but the MX record is forwarded to a company called mailprotector which basically scans for spam and virus, before forwarding it to our OpenExchange server, which of course, accepts it.
I keep reading that to make Zimbra work the MX record for the domain must resolve back to the Zimbra server. I am setting up an ubuntu machine with a static IP address that is NOT behind a router. The IP address will be 220.127.116.11 and the test domain will be ovationbooks.net and the actual host will be zimbra.ovationbooks.net.
I have complete control over the MX record. To make Zimbra work correctly do I point the MX record to the IP address 18.104.22.168? I did that but the dns reports all gripe that it isn't a FQDN? Is this OK?
Please advise and thanks very much.
