    Search the forums of go to the Split DNS article and read what's necessary for your DNS A & MX records and the /etc/hosts and recolv.conf files, there's also details on how to check you configuration is correct.

    That article is 'so good', it tells you exactly what you need to do.

    It does work if you follow the instructions. It would appear you haven't read it in detail otherwise you'd know that your A record should point to your LAN IP address not the public IP address - that has been mentioned in many forums posts (usually by me) and is also mentioned in the Split DNS article.

    I've already told you where the problem lies, you need your A record to point to the LAN IP address of the Zimbra server. The results from the following command are pointing to the wrong IP:

    Code:
    dig zimbra.si any

    Go to the 'Verify...' section of the Split DNS article and post the output of all the commands in that section.

    BTW, I was assuming that the domain name "zimbra.si" was a 'fake' domain name - it seems you have actually registered it. I'm almost certain that you are infringing the terms of the licence (the name Zimbra is a Trademark) by using that domain name, I'd suggest you review your use of that domain name (and the terms of the licence(s)) before any legal people get involved.
