Sender Policy Framework
A host's Sender Policy Framework (SPF) describes who can send mail on its behalf. This is done by publishing an SPF record containing a series of rules. Each rule consists of a qualifier followed by a specification of which domains to apply this qualifier to. For more information please see open-spf.org.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a mechanism for domain owners to indicate how mail purporting to originate from their domain should be authenticated. It builds on SPF and DKIM, providing a method to set policy and to give reporting of failures. For more information please see dmarc.org.
Raw DMARC record:
v=DMARC1; p=reject; adkim=s; aspf=s; rua=mailto:firstname.lastname@example.org; ruf=mailto:email@example.com; fo=1
|p=reject||Requested handling policy||Reject: emails that fail the DMARC mechanism check should be rejected. Rejection SHOULD occur during the SMTP transaction.|
|adkim=s||DKIM alignment mode||Strict: the Fully Qualified Domains of both the DKIM-authenticated signing domain (taken from the value of the "d=" tag in the signature) and that of the RFC5322.From domain must be equal if the identifiers are to be considered aligned.|
|aspf=s||SPF alignment mode||Strict: the Fully Qualified Domains of both the SPF-authenticated domain and that of the RFC5322.From domain must be equal if the identifiers are to be considered aligned.|
|rua=mailto:firstname.lastname@example.org||Reporting URI(s) for aggregate email@example.com|
|ruf=mailto:firstname.lastname@example.org||Reporting URI(s) for failure email@example.com|
|fo=1||Failure reporting options||Generate a DMARC failure report if any underlying authentication mechanism failed to produce an aligned "pass" result.|
