    Welcome to the forums.

    Your hosts file is incorrect -check the Zimbra Quick Start guide for the format. According to this report you don't have any MX records, check the thread DNS in a nutshell against your DNS setup.

    Sorry, I'll start again.

    You need to set-up a split-DNS. If you're server is behind a nat router then you'll never be able to connect to your server via the public IP, split-dns will do that. Have a look at this article in the wiki. Don't forget to change the entry in your hosts file.

    You'll have them hosted on an external DNS server.
