I'm moving a small company from SBS 2003 to 2011 but not migrating because of OS problems. The internal domain will be domainname.local. They are registered with GoDaddy and their
www.domainname.org website and Exchange are working properly. I want to continue with the way things are setup. Their MX record points to someone that spam filters their e-mail before forwarding it on to them. Someone else host their
www.domainname.org website. The NS and MX records therefor need to continue to point where they currently point. When running the Internet Address Management Wizard, I plan on choosing “I already have a domain name that I want to use” and "I want to manage the domain name myself".
How should I fill out the remaining fields of the wizard to not create problems with Exchange, the externally hosted website, OWA or RWA?
Also, do I HAVE to set up the spam filtering company as a Smart Host or will it function OK without that? The MX record points to them and they in turn send the mail to our IP.
