Drupal post-install configuration failed

Greetings,

we having problem with the drupal installation script. This is what we get:

[code:1]Install Script
In domain zimbra-mclink.it Downloading http://drupal.org/files/projects/drupal-5.5.tar.gz (753629 bytes) ...

Now installing Drupal version 5.5 ..

  <b>Drupal post-install configuration failed : Failed to lookup IP address for</b> zimbra-mclink.it

  More information on using this script can be found at http://drupal.org/.

.. failed! See the error message above for the reason why.[/code:1]

This should'nt happens? The domain zimbra-mclink.it effectively exist only for the dns server of the virtualmin machine. But this should be enough. Maybe the script use another method to reverse check the dns entry?

Thank you
