Post the output of the following commands (run on the Zimbra server):

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com any
dig yourdomain.mx
host `hostname`  <-- use single quotes and type the command exactly as you see it

host -v fqdn.yourdomain.com <-- use the fqdn of your Zimbra server

Thank you for your reply. I found a solution but I am not able to guarantee it will work for everyone. I logged into the server with Webmin and used the front end for Bind. From there I saw the records were not entered correctly and entered them there. After a reboot, the system worked fine. I had checked my manual entries many times but that did not seem to work but this did. Maybe it will work for others.

Can you be more specific? Iam not familiar with Webmin and the front end for bind.

[dlader]

Webmin is a graphical frontend for the server. It is freeware and a google search will get you the current version. Once it is loaded on the server, you will be able to control most server functions from the graphical interface. One of the options will be to control the bind server graphically, which will show you what your bind settings are and allow you to adjust them there.

Could you please post an example? I do not see any type of 'serial number' in my zone file to increment.

Here is the example file db.mydomain.com from the Hardy Heron install guide. Note the line I've colored in red:

;
; BIND data file for mydomain.com
;
$TTL    604800
@       IN      SOA     mail.mydomain.com. admin.mydomain.com. (
                         070725         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      mail

Hi there, i am totally stuck.
My config is:

Open VZ with Ubuntu 8.04; all packages are there; got around the problem, that Open VZ resets the hosts and hostname file.

/etc/hosts:
#::1 localhost ip6-localhost ip6-loopback
#fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters
#ff02::3 ip6-allhosts
127.0.0.1 localhost zimbra
(it has been 127.0.0.1 localhost.localdomain localhost before, but didn't help either)
# Auto-generated hostname. Please do not remove this comment.
99.99.99.99 zimbra.myserver.com zimbra mail

/etc/hostname:
zimbra

/etc/resolv.conf:

nameserver 199.199.199.199

What i did:
I checked various combinations of host/hostname, tried also adding:
search mydomain.com to resolv.conf

I tried it with different configurations.

Btw, the virtual server is remote; the reverse DNS setting has been done, whenever i enter the "hostname" command, i get as reply, what i entered in "hostname" file.
But, if i enter: hostname -a or hostname -f i will get: unknown host

I browsed almost the whole internet, hours by hours, but have not found any more clue.
Whatever i do, i will get this unknown host thing. Also, if i start the install script for zimbra, its quite the same.

DNS entry for domain and mailserver has been done, Webmin has been installed, and is up and running, i can control the server by Webmin and the internet by using the domain i set up in worldwide DNS.
the root prompt looks like this:
:~# oot@zimbra, whereas the cursor is sitting on the first "o" of this line, so if i enter any command, it overwrites the "oot@zimbra".

So i am really confused, any help would be truly appreciated.

Thank you.

You should set the hostname to a FQDN, like zimbra.yourdomain.com

[just_me]

Thank you very much for your fast reply.
