Failed DNS lookup when entries exist

[toadkicker@gmail.com]

Hello,

I am trying to install Zimbra 5 on Mac OS X 10.5 Server and when running zmsetup.pl I'm told:
DNS ERROR resolving MX for mail.stevevalenti.us
It is suggested that the domain name have an MX record configured in DNS

So I do:

bash-3.2# dig -t mx myhost.us

; <<>> DiG 9.4.1-P1 <<>> -t mx myhost.us
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 36926

The DNS server is the same machine. Just for kicks I did dig @localhost -t MX myhost.us and got the same answers. Any ideas?

sounds like your machine isn't talking to your dns server - check your /etc/resolv.conf (or whatever that is in OSX) and make sure localhost is specified as the first DNS server.

I'm receiving the same warning and I'll add a question here.

When documentation says:

Make sure that FQDN entry in /etc/hosts appear before the hostnames. If this is missing, the creation of the Zimbra certificate fails. The FQDN entry should look like this example.

should I write it exactly that way? Or should I change "localdomain" for my domain name?

nope, leave the 127 line exactly as written

Toadkicker welcome to the forums, looks like it's trying to resolve mail.stevevalenti.us see if you can change it to just stevevalenti.us when the installer asks if you'd like to try another domain instead.
Externally both mail.stevevalenti.us & stevevalenti.us have mx records that point to cnames, it should be pointing at an actual IP A record.
stevevalenti.us > mx mail.stevevalenti.us
mail.stevevalenti.us > IP

Hello...I'm having the same issue with the DNS not resolving. I've searched through many forums with no solutions. Has this issue been addressed or solved? Thanks!!
