Set Up Domains in the Organization Center
The first step you take in creating an organization is to create the initial domain. Domains within your organization are wholly-owned email domains that your admins can verify either through your web service or DNS server. For example, in the email Joe@main.com, "main.com" is the email domain. Verifying the initial domain automatically creates your organization. The user who completes domain verification will automatically become an organization admin, but this user is not required to have a GoTo product admin role. You can also add more domains to verify, or delete any domains you no longer need listed.
