Ok - i hate to ask such a simple sounding question but i will. I just had one of our domains point to a new Red Hat Linux server. this server is the main domain name server as well as it will eventually host a few domains on it. I had the internic point the domain name to my new server. no i was to setup an A record and an MX record. I plan on using the sendmail package on the server so the server will also be used as a mail server so i also need to add an MX record. I've set this up in NT but never in Linux. I'm kind of doing this as a hobby. What files do i need to modify to add the A record and the MX record and if i want to host more than one domain on one IP address what special modifications would i need to make.
