delivery report

E-mail that is sent to the originator of a previously sent e-mail (referenced as the original e-mail). It contains a list of the recipients who received the e-mail and when, plus the original e-mail's subject and submission time.

dependent client

MSMQ computers that cannot function without synchronous access to an MSMQ server (PEC, PSC, BSC, or MSMQ routing server).

MSMQ dependent clients require synchronous access to the supporting MSMQ server to perform all standard MSMQ functions, such as creating queues, sending messages, and receiving messages.

digital signature

Used to verify the source of a message and that the message was not modified

direct format name

Format used to open a queue that is not in your enterprise or when you want to make sure MSMQ sends messages to the queue in one step.

Direct format names include the address of the computer where the queue is located followed by the local name of the queue (the name specified in the queue's pathname when the queue was created).
