Resolved Incoming mail problem from certain domains only

Hello, I discovered that I am not receiving emails from certain senders. The emails are not sent to spam, they are just not delivered anywhere. I checked the mail log and found this entry which matches the sender's domain:
Wrong the essential DMARC policy parameters for 'xyzxyz.com': 'Found DMARC record containd a bad token value' (I replaced the actual domain to xyzxyz.com in this post)

I checked the DMARC and it is: v=DMARC1; p=quarantine; adkim=s; aspf=s

The spam folder is working fine, collecting emails that fail the test, but this particular domain is being completely blocked. It is a legit domain from my insurance agent! Any ideas on how to resolve this? I am able to get her emails to my gmail.

Hello, looks like there is misconfiguration for the external domain but there is the workaround https://support.plesk.com/hc/en-us/...-a-domain-from-DMARC-check-in-Plesk-for-Linux
