Hello, I am current looking at going to Exchange 2007 when it comes out. I currently have the beta set up in a test enviroment. I need exchange to be able to handle mail for both my public and internal domains. Has anyone been able to do this with Exchange 2007?

If I understand the question, you're asking about what Exchange calls "accepted domains". Have a look at <http://www.microsoft.com/technet/prodtechnol/exchange/E2k7Help/c1839a5b-49f9-4c53-b247-f4e5d78efc45.mspx> and see if that helps.

You can either add all the domains to your default recipient policy or create a recipient policy for your internal domains and one for the external domain. Regardless you can do what you want with the recipient policies.Todd Seagraves
