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=none; rua=mailto:email@example.com; ruf=mailto:firstname.lastname@example.org; pct=1; ri=86400
|p=none||Requested handling policy||None: no specific action to be taken regarding delivery of messages.|
|rua=mailto:email@example.com||Reporting URI(s) for aggregate firstname.lastname@example.org|
|ruf=mailto:email@example.com||Reporting URI(s) for failure firstname.lastname@example.org|
|pct=1||Sampling rate||1% of messages from the Domain Owner's mail stream should have DMARC applied.|
|ri=86400||Aggregate reporting interval||No more than 86400 seconds separating aggregate reports.|
