Delivery Reports

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release. A delivery report is a MAPI message with the message class string REPORT.X.DR, where X is the message class string of the original message, such as REPORT.IPM.Note.DR. Delivery reports can be generated by calling the MAPI method IMAPISupport::StatusRecips.

Delivery reports provide various amounts of information about the delivery of the original message, depending on the foreign system. If the foreign system does not support delivery reports, your gateway can generate a delivery report when it successfully transfers responsibility for a message to the foreign system. This type of report only indicates to the sender that the foreign system accepted the message.

If the foreign system supports an explicit form of delivery reports, the gateway should wait for a delivery report from the foreign system before generating a new delivery report for the sender of the message. The new report should include as much information as possible from the delivery report from the foreign system.

For more information about delivery reports, see Required Report Message Properties and IMAPISupport::StatusRecips in the MAPI Programmer's Reference Online link.
