I am new to email setups, just trying to set up a mail server at home. I have a domain name of my own and wanna test zimbra as a mail solution. I have set up a linux RHEL 4 box in my home. No DNS servers or anything its a clean installation. but i am getting stuck on finding a dns server while installing. what should be the best way to configure this system so that zimbra can send and recieve mails from internet. I have already set MX record in my domain hosting DNS settings to my home. Please help me out on this if you can.

Thanks in Advance
