Finally I solved, so I will give the helpfull information I was looking for two days ago.
The first, I will call:
Guide1 to - Ubuntu 8.04 LTS Server (Hardy Heron) Install Guide - Zimbra :: Wiki
Guide2 to - The Perfect Server - Ubuntu Hardy Heron (Ubuntu 8.04 LTS Server) | HowtoForge - Linux Howtos and Tutorials
In the Guide1 the author says refering to Guide2:
"There is an excellent, highly-detailed installation guide for this version at The Perfect Server - Ubuntu Hardy Heron (Ubuntu 8.04 LTS Server) | HowtoForge - Linux Howtos and Tutorials. I highly recommend this guide, particularly if you are new to Linux or Ubuntu specifically. The following points need to be kept in mind as you install:"
Don't follow Guide2 and after Guide1, you will have DNS problems. I have created a Google Apps Doc with my installation, maybe if a "master" wants to review it we can post it somewhere. I will post here just only the differences, in black text of Guide1 or Guide2 and red my text.
If you can not resolve your mailserver's own private IP address (NOT the public IP) using nslookup, fix it BEFORE you install Zimbra!
If your installation was successful Above, When you sign on at the command line you'll be Able to ping IP addresses public if you know Them, But You May Not Be Able to resolve names to ping and Stock Them.
Here comes problems. I try nsloopup and result is this:
root @ mailhost: ~ # nslookup mailhost
Address: 172.16.1.8 # 53
mailhost.mydomain.com canonical name = myalias.dnsalias.net.
Note: I'm using dnsalis because this is only for testing Zimbra for comparing with OX. This server will not be for production.
But I can pint to google.com, or yahoo.com
root @ mailhost: ~ # pinggoogle.es
PINGgoogle.es (188.8.131.52) 56 (84) bytes of data.
64 bytes from www-in-f104.1e100.net (184.108.40.206): icmp_seq = 1 ttl = 53 time = 54.2 ms

rtt min / avg / max / mdev = 156.793/161.607/166.422/4.831 ms
So. .. Already somehing Is it not working as the guide says?
I'm going to continue with it and we will is if it works.
Check / etc / resolv.conf and make sure it looks like this:
OK, Our resolv.conf 's files is like this. Must I change it?
root @ mailhost: ~ # cat / etc / resolv.conf
You Should Be Able to resolve names in the Outside World. Try something like "ping google.com" and if you get an answer, you're on the way.
I can do this from the very begining ... I do not know why.
Before you get to the install you Also Need to modify your / etc / hosts file:
127.0.0.1 localhost localhost.localdomain
xxx.xxx.xxx.xxx mail.mydomain.com mail
My one looks like this and I'm not to change anything.
root @ mailhost: ~ # cat / etc / hosts
172.16.1.8 mailhost.mydomain.com mailhost
In Guide2, page 3 it says:
echo server1.example.com > /etc/hostname
Both should show server1.example.com now.
Don't run it, the installation I did it, the installation doesn0t worked...
My installation is like this:
root@mailhost:~# hostname -f
Show they are different!
By the way it's all. Any comment will be welcome and maybe we must improve detailed guide, or not?
