smtp_header_checks can't change the destination, so no REDIRECT and no DISCARD. I suppose you could BCC everything to a separate postfix instance (transport table entry for the bcc recipient that points to a separate instance) and use header_checks in the second postfix to DISCARD non-matching subjects. Mail without a Subject: would not be discarded; header_checks can't test for missing headers. This might work, but I'd be concerned about mail loops. -- Noel Jones
