[Google Admin Console] Mail routing and delivery settings During your Postini transition to Google Apps, your Delivery Manager settings are moved to multiple locations on the Gmail settings page—including the Advanced Settings page, the Hosts tab, and the Default routing tab. (Note that the name Delivery Manager is not used in Google Apps email settings.) You can use your Google Apps routing and delivery options for split delivery, dual delivery, receiving routing, sending routing, content routing, attachment routing, and more. You can use the Default routing tab to set up default routing options for your domain. To review your mail routing and delivery settings after your transition, and for detailed instructions on several administrative tasks, see Mail routing and delivery: Guidelines and best practices.
