NDR message forward to recipient

NDR message forward to recipient

When an external user emails someone in my exchange server. An NDR or DSN
is created if the total size of email/attachment exceeds the limit. We
don't permit postmaster messages to escape our system and return to
sender. BUT, how can I alert the recipient in my exchange that this
happened? Currently neither the sender or the receiver knows that the
message was dropped because of too-large email size. How can i get some
automatic notification that this happened? BTW,I'm usind Exchange Server
2010.
