how to configure mail server on redhat linux without DNS configuration?
I want to configure mail server on redhat linux 5,
I have installed RedHat-5, I am having one direct IP, and having windows 2003 DNS server,
At office i am not able to configure DNS server on Linux machine (No permission to configure DNS server On RHEL-5), Having already Windows 2003 server, Is there any possibilities to configure Linux Mail server without configuring DNS server in same machine?
If yes we can configure mail server by giving direct IP or Windows DNS to mail server please provide the step to configure...
Thanks and Regards,
