True or False: Internal Directories can be populated by sending outbound messages.

The statement is true because internal directories can indeed be populated by sending outbound messages. When outbound messages are sent, the information about the sender and recipient can be recorded and stored in the internal directory of the Secure Email Gateway (SEG). This process enhances the directory by collecting contact details dynamically as communications occur, allowing for an updated and accurate internal directory over time.

This capability allows organizations to maintain an up-to-date list of contacts and interactions without relying solely on manual data entry or specific import processes. Automating the population of the internal directory through outbound messaging can lead to improved efficiency and accuracy in managing the organization's communication assets.
