It would mean I could use DSN even when my client doesn’t have support for it. This was a thing with Sendmail, using the RRTImpliesDSN option which would synthesise DSN success where Return-Receipt-To was among the headers of incoming mail.

Thanks, but I’m afraid I don’t understand how this helps. I don’t just want to send autoreplies, I want to enable DSN. In other words, I want to arrange for a message that’s injected with certain criteria (for example, it comes from a designated address) to be treated exactly as though it had been injected using the NOTIFY=delay,failure,success argument to the RCPT to command in SMTP. I can of course just do that by proxying it through a program that re-submits it with the option set, but is there a way to do it using the runtime configuration?
This is for my own use, BTW. Nobody else will be inconvenienced.
Cheers,
Sabahattin
