A missing DMARC record means you have no mechanism to tell the rest of the world how to handle emails pretending to be from your company.
The Physics of the Error
SPF and DKIM are ID badges, but DMARC is the security guard at the door. If a hacker sends a fake invoice from [email protected], the receiving mail server checks your domain's DMARC record to ask, "Hey, this email failed your security checks. What should I do with it?"
Because your DMARC record is missing, there is no security guard. The receiving server defaults to "let it through." This allows attackers to perfectly spoof your exact domain name, making wire fraud and phishing attacks against your clients trivially easy.
The Solution
You must publish a DMARC record in your DNS. However, you should never jump straight to a rigid p=reject enforcement policy without first analyzing your traffic through a p=none monitoring phase, otherwise you risk blocking your own legitimate marketing emails, CRM tools, and billing systems.
