Remarks

The PR_ORIGIN_CHECK property provides a means for a third party, such as a message transfer agent (MTA) or a messaging user receiving a delivery report, to verify the submitted message's origin. If present on a received message, this property should be copied onto any delivery report generated in response to the message.

PR_ORIGIN_CHECK replaces several obsolete properties supplied in pre-release versions of MAPI, including PR_MESSAGE_ORIGIN_AUTHENTICATION_CHECK, PR_PROBE_SUBMISSION_AUTHENTICATION_CHECK, and PR_REPORT_ORIGIN_AUTHENTICATION_CHECK.
