I tought about another possiblity. Requestes for DSN's are forwarded
from one mailserver to the next untill one server doesn't support DSN's.
Usually the mailserver before that returns a message like "this is the
last server supporting DSN. Don't expect any more messages". You could
instruct your incoming mailserver (unix running sendmail and
mailscanner) to not support DSN.
