Postfix will "reveal" both the name and the value of the element
(client, helo, sender, recipient) that triggers a reject, because
down over here in the real world, Postfix rules will occasionally
reject legitimate mail.

I doubt that it is worthwhile to complicate Postfix source code
with the output equivalent of the smtpd_command_filter feature,
but you are welcome to give it a stab.
