    Default Failed DNS lookup when entries exist

    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
    ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 2

    ;; QUESTION SECTION:
    ;myhost.us. IN MX

    ;; ANSWER SECTION:
    myhost.us. 10800 IN MX 10 mail.myhost.us.

    ;; AUTHORITY SECTION:
    myhost.us. 10800 IN NS ns.myhost.us.

    ;; ADDITIONAL SECTION:
    mail.myhost.us. 10800 IN A 192.168.1.10
    ns.myhost.us. 10800 IN A 192.168.1.10

    ;; Query time: 0 msec
    ;; SERVER: 192.168.1.10#53(192.168.1.10)
    ;; WHEN: Sun Jan 6 08:13:30 2008
    ;; MSG SIZE rcvd: 103


    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.
    127.0.0.1 localhost.localdomain localhost
    your.ip.address FQDN yourhostname
    should I write it exactly that way? Or should I change "localdomain" for my domain name?

    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
