p=reject

Establishes the rejection policy applying to email failing the DMARC test (DKIM or SPF).

pct=100

Percentage of messages from the Domain Owner's mail stream to which the DMARC policy is to be applied. Valid value is an integer between 0 to 100.

fo=0:1:d:s;

Establishes the failure reporting options:

  • fo=0: Generate a DMARC failure report if all underlying authentication mechanisms (SPF and DKIM) fail to produce an aligned “pass” result
  • fo=1: Generate a DMARC failure report if any underlying authentication mechanism (SPF or DKIM) produced something other than an aligned “pass” result
  • fo=d: Generate a DKIM failure report if the message had a signature that failed evaluation, regardless of its alignment
  • fo=s: Generate an SPF failure report if the message failed SPF evaluation, regardless of its alignment
