3.1.5.1.7 Delivery Receipt Message Processing
The protocol MUST perform the following steps to process a delivery receipt message:
Duplicate detection (see section 3.1.5.1.11).
Inserting the message into its destination queue (see section 3.1.5.1.12).
No specific steps for processing a delivery receipt message are required; in particular, there is no correlation of the original message requesting the delivery receipt.
