How to block incoming emails that do not pass DMARC

What type of hardware are you using: VPS bought online
What YunoHost version are you running: 11.3.0.2
How are you able to access your server: SSH

Describe your issue

I often receive SPAM emails that try to spoof someone else’s domain and because of lack of DKIM signature, they don’t pass DMARC test.

Is there a way to make the mail server in Yunohost automatically reject messages that come from a domain with DMARC enabled, but do not pass DMARC tests?
