    Default DynDNS and Zimbra

    I have posted on this once already, but my post wasn't really geared towards this.

    Is there anybody on here the has been able to get Zimbra up and running using a DynDNS domain? I have signed up for Custom DNS through DynDNS and have my domain and MX records setup there, however, when I try to install Zimbra it still gives a lovely DNS Error. I have modified my hosts file as the Zimbra guide says, but that doesn't seem to help.

    I am almost ready to give up because its just frustrating me, so any suggestions or help would be greatly appreciated.

    If you are behind a NAT device then you'll need to setup a split-DNS, have a look in the WIKI for details. Are you sure that your DNS records are correct? You can check them here.

    I have setup splitDNS per this guide:
    http://www.tickus.com/?q=node/15

    I am behind a router, but I am not sure if it is NAT or not. The A name records were automatically created for me when I brought my domain to DynDNS. I used the host command from linux to check my setup and it appeared to be ok there.

    So maybe the SplitDNS guide I found is wrong.

    *Update*
    I have since switched from using Custom DNS to using my registrar's service since I can specify MX records through them as well. So basically I have an MX record pointing to a free DynDNS Dynamic Host (ex: jzserve.dyndns.org) just so it can grab my external IP.

    These are my results from Pingability: http://pingability.com/zoneinfo.jsp?domain=jzeller.com

    However, my server isn't running at the moment, so it says it cannot connect to the MX host. Everything looks right to me, so its just flustering me.

    Also thank you phoenix and jholder(different thread) for all your help.

    Well what are the symptoms?

    What is the hostname you are installing onto?

    What does that resolve to from the machine you're installing on?

    The symptoms are that during Zimbra setup when it goes to configure it gives me a DNS ERROR, so I assume it is not seeing the MX record properly.

    The hostname I am trying to use is jzeller.com which I have already setup an MX record for which points to jzserve.dyndns.org with a priority of 10. This has been setup using my registrars DNS options.

    I did the split DNS setup using the link I posted above, and I just kind of assumed that it was a good tutorial. Since I understand the concept of Split DNS, but I don't know BIND very well.

    As far as what it resolves to I will have to post that later since I am at work and don't have access to the machine. SSH is blocked here.

    I might be wrong but I would have thought it's more likely to be an A record issue than MX. MX should report a specific error in the installer.

    jzeller.com is a domainname, what hostname ie FQDN is the server called, and what does this resolve to on the server?

    As far as what it resolves to I will have to post that later since I am at work and don't have access to the machine. SSH is blocked here.
