Sorry about that - I thought I should substitute hostname with my hostname.
When writing it exactly as you did, I got this:
(and I cannot get the CODE tag working - maybe it's my old Win98 with IE6 thats the problem):
root@ibm5600:~# host `hostname`
Host ibm5600 not found: 3(NXDOMAIN)
The two dig commands shows the same as before:

but now comes the funny part. I wanted to copy the html 403 error, but now the wget works fine - I might have rebooted a couple of times.

I used the tgz from my windows PC (transfered on CD) and the installation went on like a beauty. The only tricky thing was that I - as mentioned in the guide - had to change domainname from ibm5600.giver.info to giver.info.
So now it's up an running and accessible from the outside world as
Zimbra and from my lan as
https://10.10.10.235:7071.
Thank you very much for your help!
