dmarcian

dmarcian displays the email authentication status of your domains directly from your admin panel. The syntactic accuracy of DMARC, SPF, and DKIM* records are evaluated both on-demand and daily. While each authentication technology may support different policies (e.g. DMARC p=none vs. p=reject), the plugin does not take into account current policy and reports only on record validity.

(*) DKIM: DKIM selector (s=) is required to enable the DKIM check.

DMARC adds new features to email:

• strong security controls can be applied against fraudulent email
• email delivery is simplified
• sender identity can be reliably established
• visibility is granted on how email domains are being used around the internet

DMARC (Domain-based Message Authentication, Reporting & Conformance) builds on the commonly used SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Message) protocols and adds additional features of From domain alignment between the protocols, instructions for Receivers on failure handling and reporting capability.

• SPF: wiki page and video overview.
• DKIM: wiki page and video overview.
