Spam blocking with Opendmarc?

Question

postfix

Recently, spam from the gmail.com domain has begun to pour in. Oddly enough, Google allowed this in its policy:

dig +short txt _dmarc.gmail.com
"v=DMARC1; p=none; sp=quarantine; rua=mailto:[email protected]"

Is it possible to block such letters on your mail server using Opendmarc? The standard option in the settings "RejectFailures true" in the case when the policy of the domain owner p=none does not work.

Answer 1

"Experts" did not offer anything, I had to decide the issue myself. Using policy-spf-python, add domain gmail.com to the block list when not passing the SPF policy

Answer 2

I don't care about spam, I have rspamd
