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

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

[bkarthick4u]

cat /etc/resolv.conf
search server.example.com
nameserver 10.0.0.17

cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
10.0.0.17 server.example.com

host server.example.com
server.example.com has address 10.0.0.17
dig example.com

This is incorrect it should be as follows:

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.

[bkarthick4u]

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.

[bkarthick4u]

host `hostname`

server.example.com has address 10.0.0.17

this is the output am getting

Will you answer my question and post the output from the dig commands I asked you for earlier.

[bkarthick4u]

dig example.com mv

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.
