DMARC

p=none, p=quarantine and p=reject are three primary DMARC policies that can be implemented by organizations to protect themselves from email spoofing, where p= function representing policy equals.

It can be more difficult for bad actors to successfully target end users and get their personally identifiable information (PII) or other sensitive information by implementing a DMARC policy. It can be made harder for the branding to be used in phishing and email spoofing attacks for organizations that put DMARC policies into effect, protecting the reputation of their brand. It helps create more trust on the internet by making it more difficult for attackers to create attacks using logos and identities of another brand. Emails sent from the domains of organizations are more likely to reach the inboxes of end users when they implement a DMARC policy. More exposure for brands and organizations are generated which often lead to more sales with increased deliverability rates.

Alignment and Reporting are basic elements of DMARC. Organizations need to follow the standard enforcement route and pay attention to inactive domains in order to most effectively implement a DMARC policy.
