    Default DNS ERROR resolving ... mewbie

    Hi there

    I am a total beginner in both zimbra and linux!

    I get 2 errors when i install:

    DNS ERROR resolving mail.pmjdk.dk
    It is suggested that the hostname be resolveable via DNS
    Change hostname [Yes] n


    DNS ERROR resolving MX for mail.pmjdk.dk
    It is suggested that the domain name have an MX record configured in DNS
    Change domain name? [Yes] n

    I'm not 100% what to do - i tried to follow the guide, but in the field of DNS it doesn't say that much! (what to setup and so on)

    I own the site: pmjdk.dk and i changed the IP adresse in dns under A pmjdk.dk and A mail.pmjdk.dk to point at my wan ip address and (for test purpose) my local ip is DMZ

    I can see the login page if i type https://*mywanip*:7071/zibraAdmin - but not if i type https://mail.pmjdk.dk:7071......

    If you reply, please tell me excatly what to do and how to do it - thanks

    Michael

    I saw you ask for this in other posts - so.......

    You need to have a MX (Mail Exchange) record added to your DNS which will point your domain pmjdk.dk to mail.pmjdk.dk.

    pmjdk.dk MX(10) mail.pmjdk.dk

    Sorry, try the following as I mis-read your post
    Code:
    dig pmjdk.dk  mx
    also just to check all your ZCS services are running
    Code:
    su - zimbra
    zmcontrol status

    Code:
    cat /etc/resolv.conf
    cat /etc/hosts
    please as I reckon your server is behind a firewall and has a private IP address ?

    I think i just got something from it !?
    mail.pmjdk.dk. 7200 IN A 62.242.36.51

    that IP is the old ip from before i changed it - not my wan ip address
    I guess that is the problem??? - the changes haven´t taken affect yet.
    How long does that normally take - it was changed over 24 hours ago?

    My local IP is DMZ - so it should be totally exposed!

    The reason why I ask is that when you performed the dig the queried server had a private IP
