I'm coming from a windows background and little experience with linux and DNS. I'm at a company that is growing and needs the benefits of shared calendaring but Nobody wants to go with exchange. I'm personally trying to set up the open version of Zimbra on a copy of Suse Linux to get a feel, I have a domain that I purchased and am using http://www.dyndns.com/ for dynamic DNS to point to my comcast ip and I'm behind a NAT router.
I'm having a time figuring out how to set up zoning at dyndns and whether or not I need a DNS server on my home machine.
I'm assuming my linux machine has to have a host name on my domain? Something like host.example.com
I want to be able to set up a mail server that is called something like mail.example.com that can recieve email at something like firstname.lastname@example.org
Currently when I go through the Zimbra set up I get this:
DNS ERROR resolving host.example.com
It is suggested that the hostname be resolveable via DNS
I have "host" resolving to to my private IP in my hosts file. I read in another thread that I might need to set up a DNS server so that Zimbra will resolve host.example.com to my private IP rather then my public IP Address before it looks at my ISP's DNS servers that resolve my domain to my public IP Address?
Also what should I have in my dyndns zoning file?
Currently in my ZOning file I have mail.example.com as my Mail Exchanger.
Also is the fact that LDAP fails to load possibly because of this domain confusion?
