DMARC Test Settings


This help section describes the DMARC Test Settings dialog of ORF.

Evaluation Tab

Verify all alleged author domains

By default, many email clients only display the "display name" part of the From header to the user reading the email, which gives scammers the opportunity to display a fake email address and hide the real author's address. Enabling this option will allow the DMARC Test to check the email against the DMARC policies of domains found in the entire From header field - not just the domain in the actual "address specification" part.

Enforce compliance with DMARC's header requirements

In order to be processed by DMARC, the message header must contain at most one "From:" header field with at least one syntactically valid email address. Messages with blank or multiple "From:" header fields are prohibited by the Internet Message Standard (RFC5322). If you enable this option, the email will be blacklisted if it violates these requirements.

Take no action if a "p=none" policy is discovered

Domain owners who wish to test their published DMARC policy may request that their mail not be blacklisted if it fails the DMARC check. Enable this setting if you want ORF to comply with this request.

Adhere to the domain owner's "p=quarantine" policy

This option allows you to set a different filtering action for emails that fail the DMARC check, but should be treated less strictly according to the sender's DMARC policy.

Exceptions Tab

Author Email Exceptions

Use this list to exclude specific senders from the DMARC test by the From header address or domain.

Sender IP Exceptions

Use this list to exclude specific senders from the DMARC test by the sender IP address or network range.

Log Tab

Always log DMARC check results

Set this checkbox to log DMARC evaluation results, even if the email was not blacklisted. The evaluation result appears in the log as a separate entry and logged only if the sender published a DMARC policy.

Log SPF and DKIM check results

When a DMARC record is found for a sending domain, ORF runs the SPF the DKIM tests "silently" as part of the DMARC validation process. Set this checkbox if you want ORF to log the results of these sub-tests as well. The SPF and DKIM log detail levels are governed by the log settings of the SPF and DKIM tests.
