    If you do not know what you are doing, and this is actually important, hire someone.

    I get paid for that level of support.



  • if i could have hired i would not have messaged here Bro... Wow never thought people here very professional ;)

    This should cover anything that you need to know to get Zimbra installed and up and running.

    but when configuration is complete i tried to send email like [email protected] to [email protected] it not receiving..am confused where i went wrong.. i shud be able to send only internal domain.

    So you are trying to send FROM Zimbra TO Zimbra, so in theory the email has never left the Zimbra server? One of the first, and most confusing things, is that Zimbra has to see itself as the owner of the domain, otherwise it will go out looking for it.

    In Zimbra itself, the first things to check are the hostname of the box and that the domain you want to use have been set up. Then you want to ensure that your MX records correctly match what Zimbra believes.



  • @scottalanmiller yes i shud be able to send zimbra to zimbra , i dont need to send external domain(gmail, yahoo, etc) if this works then good,
    but i followed your procedure only for some reason it did not work... maybe i might be doing work in DNS settings let me start from scratch..

    My procedure is only to build the server. Setting up your domain still needs to be done. And that part is unique to you. Have you gotten your MX records set? Does the MX record match the hostname of the Zimbra server? Is Zimbra set to look to that hostname for resolution? Is DNS working on the host?



  • @scottalanmiller ok i haven't set the MX Record yet.can you help on that please



  • more detailed information on setting the MX Record will be really helpful.

    @nagendra said in Zimbra installation and configuration (internal use only):

    @scottalanmiller ok i haven't set the MX Record yet.can you help on that please

    Okay, have to start there as Zimbra demands that it be in place even for local email delivery.

    How is your DNS for your internal domain handled? For us, our email domain still is public, so it is a public DNS that we need to modify. Is the domain that you are emailing one that is public, or just a fake, internal one?



  • @scottalanmiller said in Zimbra installation and configuration (internal use only):

    r just a fake, internal one?

    for us also domain is public .future my office might need a option to send email outside...not sure

    Then on your main DNS host, you will need to make an MX entry that points to your new Zimbra server.



  • @scottalanmiller ok can u show me any example how to add MX Entry

    @scottalanmiller ok can u show me any example how to add MX Entry

    What DNS host do you have?

    Also, the hostname issue is probably the bigger one. What are your settings there?



  • Like i need to add MX Record in my Active Directory DNS Manager ??

    No, Windows DNS (there is no AD DNS) is for your local domain, not your public one.

    He just rebuilt fresh, so we are starting from scratch.

    Check your running services and make sure that all is well...

    Then look here to see the mail queues.

  • i cant see any mail queue...

    Check to see if the email that you sent was delivered.


  • Service Provider

    So an email did not go through, but nothing is in the queue? That's really strange. That suggests that the server reached out and sent the email elsewhere.

    What is the last ~50 lines in /var/log/maillog

    I think that you may need to edit your /etc/hosts file...

    Your local IP address and hostname and FQDN to the first line and remove any other references to your host name.

    Not totally sure, but might as well. Just reboot.



  • are you trying to send from the Web Mail Interface of any Mail Client like " Outlook and Thunderbird " ?.



  • also try to telnet from any host in your LAN to the zimbra server

    telnet server_ip 25
