Delivery receipt request style
The,  ,  , and   channel options control which sort, if any, of delivery receipt request the MTA constructs from "foreign" delivery receipt requests, such as for messages coming in to PMDF via PMDF-LAN, PMDF-MR, PMDF-X400, or PMDF-MB400 channels, or via the addressing channel. On OpenVMS, these keywords also control the interpretation of delivery receipt requests from VMS MAIL or PMDF MAIL via L or D channels. For PMDF-LAN, PMDF-MR, PMDF-X400, and PMDF-MB400 channels, these keywords also control which sort of delivery receipt request the MTA will convert into the respective "foreign" delivery receipt request. (In the case of PMDF-X400, note that the keyword on the MIME_TO_X400 channel controls the behavior in both directions, to and from the X.400 world.) The current default is  meaning to turn "foreign" delivery receipt requests into the old ad-hoc header style delivery receipt requests. requests that only NOTARYg style delivery receipt requests be generated; this may become the default in a future version. causes the MTA to generate both a header style and a NOTARY style delivery receipt request when seeing a "foreign" delivery receipt request; setting this may result in two delivery receipts from MTAs that support both forms of delivery receipt request. causes the MTA to ignore (suppress) incoming "foreign" delivery receipt requests.
