-- Gateway fails to send AS2 MDN receipt automatically after receiving the payload from the sender successfully.

# In Gateway the user by default to manually right click on the transfer from the transfer list screen on Gateway Navigator & then left click on the ack option to send the MDN receipt.

If this has to be automated, one has to edit the Remote site being using in the AS2 transfer (Usually the remote site configured for that specific client but in some cases it is TAS2) & set the acknowledgement option to monitor.
