It's something I plan to do when I eventually get round to it.

I was originally going to defer in the third case (some want it, some
don't), remember the sender address, and then for a while accept only
one RCPT per MAIL FROM that address, so that I could then accept or
reject individual copies when it's retried.

It would probably be better to fakereject with a message like the one
you show above though, and actually deliver it to the recipients who
want it.
