PMDF System Manager's Guide

When PMDF generates a notification message (bounce message, delivery receipt message, etc.), there may be both an "original" form of a recipient address and an altered "final" form of that recipient address available to PMDF. PMDF always includes the original form (assuming it is present) in the notification message, since that is the form that the recipient of the notification message (the sender of the original message which the notification message concerns) is most likely to recognize. The includefinal and suppressfinal channel keywords control whether PMDF also includes the final form of the address. Suppressing the inclusion of the final form of address may be of interest to sites that are "hiding" their internal mailbox names from external view; such sites may prefer that only the original, "external" form of address be included in notification messages. includefinal is the default and means to include the final form of the recipient address; suppressfinal causes PMDF to suppress the final address form, if an original address form is present, from notification messages.
