OK, for anyone to help you with this you are going to have to clarify a few things...

I replaced my RHEL 5 with CentOS 5.6. these are my configuration files.

Which OS are you currently working with? This post makes it appear you've switched to CentoOS 5.6 (a good move IMO), but then subsequent posts make me think you are back to RHEL.

i don't have bind installed on RHEL 5. moreover i tried to install it but i can't understand the problem. it is installed fully but there are no associated directories or files created of bind. no named service. i spent a lot of time but could not solve that. kindly help me out. is there any alternative to get out of this problem? i have installed webmin1.560 on the same machine. but there is no bind server listed in the servers portion. can i do the same job using webmin without bind? is there any other alternative? please help me out.

Totally confused here. I don't know if it is under RHEL 5 or CentOS 5.6, but you obviously have Bind installed somewhere. Additionally, webmin is a web-based tool which attempts to make administering services like Bind, Samba, etc. easier than having to do things at the command-line level. It is not a replacement for Bind. There are alternatives to Bind for setting up DNS services under Linux, but Bind is the most popular and you will be more likely to find help on these forums at least if you stick with Bind.

Again, not sure what system you are running on (RHEL or CentOS), but these messages indicate there is a problem with your named.conf file on lines 28 or 29. The named.conf you previously posted only has about 15 lines, so either you've made changes to it, or you are working with the wrong named.conf file.

I am using two machines, RHEL 5.3 on one computer and CentOS 5.6 on another. I should have not posted them together.

when i run

/etc/init.d/named start

on CentOS 5.6 it fails generating the following log.

i had configured the system using the following link

Somehow or the other, it started working on RHEL without using bind. the mails are now delievered to inboxes as well. can you tell me what problems i might face for ignoring bind?

You will have problems getting mail delivered to your server unless you've configured a Split DNS set-up, without that you server will not be able to resolve it's own IP address for mail delivery. You need to check the configuration by running all the commands in the 'Verify...' section of that article.

You should also post the full output of the following command:

zmcontrol status

Kindly help me out in my bind configuration. i am getting the following error during zimbra instalation.

Do not start a new thread when you already have one on the same subject, I'll merge this with your other thread.

You need to read my comments in that thread on what's needed and the Split DNS article for full details of the requirements for DNS configuration on a LAN - everything you need is there including the commands to check your configuration.
