[Postini Admin Console] Domains [Google Admin Console] 
Review your domains Each of your domain names is transferred to the Domain settings page in the Google Admin console. This might include just a single primary domain, or it may also include additional domains or domain aliases that were part of your Postini configuration. After your service transition is completed, we recommend that you confirm that domain aliases and non-primary domains are copied over. Note that domains are displayed differently in the Google Admin console. For example, in Google Apps there is only one primary domain. For instructions and details on your domain setup in Google, see Add domain or domain aliases, Managing multiple domains, and Limitations for multiple domains.
