Furthermore it would be rather difficult for them to do anything with DSNs, given that DSNs are part of the message envelope, and that the relevant RFC makes it explicitly clear that MTAs are *NOT* to insert anything into the headers or body in order to indicate the presence, or an absence of, a DSN. -- Sam
