reduce spam by sending a mailer-daemon?

[cln]

Is it possible to reduce spam by creating a rule that would send a
mailer-daemon?

I assume that spammers would probably snif if emails do not work
right? so why not setup a rule that will return emails if the subject
is "little bleu pill" or whichever/whatever.

Comments?

That's a bad idea. A lot of spam comes in with From addresses that the spammer has "borrowed" from unsuspecting legitimate mail users. Your idea would serve no useful purpose and would wind up sending unwanted mail to those legitimate addresses.

Wrong. spammer software doesn't listen for replies and doesn't pay
attention to rejects.

Non-delivery reports cannot effectively be mimicked by client software.
NDRs are server-generated messages.
