I am trying to install zimbra on on an amazon elastic cloud instance.
I have a static external ip address (elastic ip address) with a dns entry and MX records pointing to this external ip address.
When I attempt to install zimbra, it wants to use the dhcp name of the server, which is subject to change. I see others have done this and their install breaks on a restart of their server.
I read about the split dns setup, but this still assumes a static ip address on the server. I tried changing the domain for the install to (pimpmyclone.com) but because this is the external interface for the server, the installation will not continue.
Any ideas on how to proceed with this problem? I included the text message that zimbra gave when it could not proceed with my domain name change.
