DMM stands for Domestic Mail Manual, which serves as an important reference for postal services in the United States. The DMM outlines the regulations, standards, and procedures for sending domestic mail, including guidelines on various mail classes, pricing, and addressing requirements. It is essential for postal workers and anyone involved in the mailing process to be familiar with the DMM to ensure compliance and efficient mail handling.

Other options, while related to postal themes, do not accurately describe the comprehensive set of rules and information the DMM provides. Direct Mail Marketing, for instance, refers specifically to marketing strategies using mail products and does not encompass the broader regulations of mailing processes. Daily Mail Management and Department of Mail and Messaging suggest operational or structural aspects that do not reflect the regulatory focus of the DMM. Thus, recognizing the DMM as the Domestic Mail Manual is crucial for understanding its role in the postal system.
