Hi All,
I have been using zimbra successfully for about a year BUt now I have a problem.
i have installed new servers and renamed the domain.
It was originally called prentonhigh.internal and my zimbra server was named email.prentonhigh.internal BUT now my new domain is called prentonhigh.local.

I am having problems when emails are sent to the zimbra users and looking in the mail queue I can see that the emails are arriving at the server but I get the following error...

host or domain name not found. name service error for name=email.prentonhigh.internal type=a: host not found, try again.

Can someone suggest what I need to do to fix this, should I change something on my dns server or would it be a setting on the zimbra box itself.

Thanks in advance.
