Wietse,

On my mail server, this is the resolv.conf

# cat /etc/resolv.conf
# Generated by NetworkManager
search hldns.com
nameserver 199.249.188.251
nameserver 199.249.188.252
nameserver 199.249.188.253

These are all my own name servers however on my NS VMs, the resolv.conf has
nameserver 127.0.0.1
nameserver 8.8.8.8
nameserver 8.8.4.4

There was no mention of this on any of their instructions for DQS.

What exactly should be in there?


Thank you, 
Steffan Cline

What is in your resolv.conf file? You *MUST* use your own DNS
resolver which talks directly to the Internet, not through your
ISP's resolver or some public DNS provider.
