How can I reject mail that does not have a DMARC policy enabled? Using Postfix 3.6.4 and OpenDMARC 1.4.2.

Roll your own milter using the python3-milter?

Missing dmarc records is not a dmarc fault, so you just have to reject those without a dmarc.

Maybe reject is too stronk, and a quarantine is better? Will help you debug at least if theres e-mail you are missing
