Message Audit Logs and maillog at INFO level show "554 5.7.0 manually failed" as the Delivery Failure reason for a message on Symantec Messaging Gateway (SMG)
Updated On:28-03-2012 07:38
A message is removed from the delivery queue without generating a Non-Delivery Report (NDR) on SMG.
554 5.7.0 manually failed
This behavior is by design.
Please note that when a message is manually deleted from the delivery queue either from the Command Line Interface (CLI) or from the Control Center, the message is removed from the queue and a Non-Delivery Report (NDR) is NOT generated.
