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
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

Can anyone help me with this.
