Issues found:
The DMARC policy is inactive. Attackers can send emails pretending to be you. Analyze your DMARC reports to fix this.
DMARC aggregate reports are disabled. You can't see if attackers are sending emails in your name or if your messages are passing or failing. Fix this by adding a "rua=mailto:" tag.
DMARC forensic reports are disabled. Some email providers send these reports, letting you spot attacks or misconfigurations early. Fix this by adding a "ruf=mailto:" tag

What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol. Admins create its record syntax and add it to DNS as a TXT Record. It helps them set policies for unauthorized emails and receive reports on outgoing email activity. Domains without DMARC are open for fraudsters to send emails on your behalf.
