useresent keyword controls the use of Resent- headers
when gatewaying to environments that do not support RFC 822 headers.
This keyword takes a single integer-valued argument. Legal values
|+2||Use any Resent- headers that are present to generate address information.|
|+1||Only use Resent-From: headers to generate address information; all other Resent- headers are ignored.|
|0||Do not use Resent- headers to generate address information. This is the default.|
useresent keyword applies for the l
(lowercase "L") channel on OpenVMS, and for PMDF-MR,
PMDF-X400, and some PMDF-LAN channels.
Note that the default of 0 constitutes a change in the behavior of the OpenVMS l channel compared with PMDF version 4.3 and earlier.
