Fill in the blanks: An entry that has been _______ on a user's Managed Senders list is always superseded by a _______ Senders policy created by an Administrator.

The correct choice highlights the functionality of the Managed Senders list and the administrative policies that govern email handling. When an entry is classified as X-Trusted Senders, it designates certain senders in a highly trusted category, significantly impacting how emails from these sources are handled.

This X-Trusted Senders designation typically bypasses many filtering processes to ensure that important communications from these senders are received without obstruction. On the other hand, an Auto Allow policy set by an Administrator takes precedence over individual user settings. This means that even if a user has marked a sender as X-Trusted, if the Administrator creates an Auto Allow policy that includes wider criteria or specific senders, that policy will override the user’s explicit trust designation.

In essence, the interaction between Managed Senders lists and Administrator-enforced policies ensures that organizational standards regarding email security and trust are maintained, regardless of individual user preferences. This promotes a more unified approach to email security, minimizing risks from potentially harmful or unwanted emails that may slip through otherwise.
