Nice feature!

If I read the manual correctly, putting

Disposition-notification-to::*
ACTION:REJECT Disposition-notification not allowed
Return-Receipt-To::*
ACTION:REJECT Return receipt requests not allowed
Read-Receipt-To::*
ACTION:REJECT Read receipt requests not allowed
X-Confirm-reading-to::*
ACTION:REJECT Read confirmations not allowed
Return-Receipt-Requested::*
ACTION:REJECT Return-receipt not allowed
Generate-Delivery-Report::*
ACTION:REJECT Delivery-report not allowed
Mail-Reply-Requested-By::*
ACTION:REJECT Reply-request not allowed
X-Confirm-reading-to::*
ACTION:REJECT Confirm-reading not allowed

in the CONTENT_FILTER should reject messages with any of the known
delivery confirmation requests.

BTW, there's a good header reference at:
