Hi,

Thank you for your prompt reply. I checked split DNS entires as suggested by you but I have some confusion with my existing setup. Basically I have following setup in our company.

1. DNS server running bind ( 4 domains). In dns server I have entries for both private and public networks. Like if a user is in the company's network he can access mails, websites, ftp locally. (HAVING 2 ZONE FILES FOR EACH DOMAIN)
2. mail server qmail (for 3 domains - which I want to transfer to zimbra eventually, once it is successful.)
3. OpenLDAP for user authentication on private IP.

my new setup for zimbra:

zcs server for 4th domain (using existing dns server), which has LDAP, postfix and everything that comes with it by default.

Now I'm wondering as to how can I implement split DNS in this case.

Your help in this regard is highly appreciated. I liked zcs features and want to move all our domains to zimbra server. (squirrelmail sucks most of the time)

Thanks & Regards
