Reject messages using DLR
April 8th, 2023 by Melrose Labs Support
The SSG now supports using DLRs when rejecting customer messages using rules. Previously, rejecting messages was only supported with a negative submit_sm_resp returned in response to the customer's submit_sm.
When using DLRs to indicate rejection of a message, the message will be accepted by the platform (i.e. submit_sm_resp contains message ID from the platform) and then a DLR will be issued showing the message to be undeliverable/cancelled/rejected (as configured).
See reject message in Rules for documentation.
