    Default [SOLVED] Zimbra can send couldn't receive

    Hello,

    I have domain name registered at Browser Update Page and real IP address, after installation I went to Admin Console and I unchecked the enable DNS lookup, now I can send locally and receive.

    After I finish the configuration of redirecting the zimbra.mydomain.com from godaddy control panel I'm able to see the Zimbra login page and I can send to gmail but when I reply to zimbra server there is no NDR message come to gmail and at the same time I'm not receiving it.

    So how do I make the correct configuration in order to be able to receive on zimbra server?

    Any idea will be appreciated!

    Cheers,

    Why did you uncheck the 'DNS lookup'? Couldn't you send/receive before you did that?

    What do you mean by 'redirecting the zimbra.mydomain.com', do you mean changing your DNS records? If so, have you done any checks on your records to see if they're OK? Try Pingability.com: Web Site Monitoring and Alert Service for a quick DNS test.

    Any error messages in the log files?

    Hello phoenix, Sorry for the delay to reply,

    I installed zimbra and I can send, but now I'm confusing with the configuration of the MX, in my previous case the DNS server was on windows beside Zimbra server, but now I'm trying to configure the MX record direct from the webhosting cPanel Lunarpages.

    What I supposed to enter in zimbra server resolv.conf (which nameserver?).

    From the DNS zone of the domain name which records I must change?
    What I supposed to enter in the A record and the MX record?

    Please help, Although I can send to the gmail and when I reply from gmail and receive but couldn't deliver to the Zimbra Inbox

    Cheers,

    Is this server on a public IP (and/or behind a firewall) or behind a NAT router?
    Regards

    In the resolv.conf you include the IP of your local DNS server only. For the public DNS records you point them to the public IP then forward port 25 (and any others you need) to the LAN IP of your zimbra server.

    Has your ZCS server been installed using a FQDN which is your actual domain name, and is it configured to use your public (real) IP ?

    So I must enter two nameserver?

    here is my current configuration:
    nameserver xx.xxx.xx.xxx

    mail.domain.com A 192.168.1.8
    mail.domain.com MX 0 mail.domain.com
    domain.com MX 0 mail.domain.com
    Has your ZCS server been installed using a FQDN which is your actual domain name, and is it configured to use your public (real) IP ?
    I'm following the same installation steps of my company and it's working well the different now is with the DNS only, I'm confusing with the nameserver, as I said In my company the DNS was locally, but now because the domain name is hosted at lunarpages I changed the MX record from the cpanel, My question is what I supposed to enter in the nameserver which is the DNS of zimbra server? is it the my lunarpages name server (ns1.lunarpages.com)? because at my company I put the local DNS 192.168.1.6

    Thank you in advance....

    Cheers,

    You need two sets of DNS records on two different servers. External records (hosted on an external DNS server) to point to your public IP and a local (internal to your LAN) DNS server with records pointing to the LAN IP of your server, it's known as Split DNS (or Split Horizon DNS) and you'll need to set-up a local DNS server.

    Okay I will check the mentioned link as you provided, but is it possible to install the bind9 at the same server of zimbra? or it must be separated?

    Cheers,
