Delivery confirmation request - Invalid information sent

[plaval31]

(We are running Domino servers R 5.0.9a)

When someone, from the Internet, send us a mail with a delivery confirmation request, he receives :

1: the correct delivery confirmation information containing the right recipient address.

2: he also receives a second mail like :
" DELIVERY FAILURE: Enhanced Mail SystemStatus Code (RFC1893): 2.0.0"
"Your message
Subject: TEST
was not delivered to:
noreply@ourdomain.com
because:
Enhanced Mail System Status Code (RFC1893): 2.0.0

(When no delivery confirmation is requested, no false alarm is sent.)
How can we get rid of that?

How to get rid of it and a little bit more:
Recommend to turn off delivery confirmation for all internet mails. Recommended mostly because all the use and in particular 'misuse' of emails as is today, sales persons, possible spam, address collectings etc. and whatever else ideas and methods that exists out there...

Easy to do in R5 and newer.
