I'm trying to come up with the best way to set up Reverse DNS. Here's my current configuration.
-Domain managed by Network Solutions
-ISP is AT&T
-I house an Exchange 2003 server
NetSol says they can't host RDNS without also hosing email; so that's out. AT&T says I need to give them at least 1 Forward DNS domain before they'll manage RDNS.
If AT&T is being strait with me then I think I have 3 options but I have no idea which one is best or if there's another safer better option.
1) Give AT&T my primary domain to manage so they can then manage the RDNS for that domain
2) Give AT&T an unused domain to manage so they can then manage the RDNS for the primary domain
3) Create a new domain solely for the purpose of AT&T to manage a domain and then be able to manage the RDNS for the primary domain
