Dns error

[unitedpro]

Hi
I am installing zimbra in centos. I am getting a Dns error, I am new linux.
I am getting following error

""Setting defaults...No results returned for A lookup of up.local.unitedprotech.com
Checked nameservers:
xxx.xxx.xxx.xxx Dns 1
xxx.xxx.xxx.xxx Dns 2

DNS ERROR resolving up.mydomain.com
It is suggested that the hostname be resolveable via DNS
Change hostname [Yes]""

Can anyone help me with this.

Regards
Suresh

All over the forums and the Product Documentation and the wiki there are details of what you need to install Zimbra, go to the Split DNS article and set that up.
