    This has been covered many times in the forums, did you search before post?

    Post the output of the following commands (run on he zimbr
    Code:
    a server):
    
    cat /etc/hosts
    cat /etc/resolv.conf
    dig yourdomain.com mv
    dig yourdomain.com any
    host `hostname`  <-- use that exact command with backticks not single quotes
    Regards

    This is incorrect it should be as follows:

    Code:
    127.0.0.1  localhost.localdomain localhost
    10.0.0.17 server.example.com server

    The output from this is incorrect run the command exactly as I've given it to you, do not change it, do not add your hostname to it.

    Post the output of the dig commands that I've asked you for.
    Regards

    i should execute the command as

    host hostname or host 'hostname'

    if i execute both this command am getting

    Host hostname not found: 3(NXDOMAIN)

    Neither is correct, you should use backticks not single quotes as I mentioned earlier. Try doing it the easy way and copy/past the command I posted earlier into a terminal.

    Well, as you can see from the output you've provided there are no DNS A or MX records for example.com - you need to set them up correctly for the installation to work.
