The information in this article applies to:

  • Microsoft Mail Gateway to X.400, versions 2.1, 3.0, and 3.2

When it builds an X.400 message, the Microsoft Mail Gateway to X.400 always sets the P1 per-recipient flag to request basic non-delivery notification for the originator.

If the originator requests return receipt notification, the X.400 gateway sets the P1 flag to request:

  • basic non-delivery (message could not be delivered)
  • confirmed-delivery (message has been delivered)
  • confirmed-read (recipient has opened message)

Confirmed-read notification always accompanies confirmed-delivery.
