Thanks for the explanation, but I already know you can request a success DSN when sending email. My questions is different in that I only want a success DSN if the mail has previously generated a delay DSN and I don't want success DSNs all the time. Basically I want a "your mail is no longer being delayed and has been delivered to the next hop" DSN. This doesn't seem to be covered by the RFCs so I understand if this is not possible, although I'd consider it a useful feature.
