DMARC Validation

DMARC (Domain-based Message Authentication, Reporting & Conformance) defines how an incoming email should be handled depending on the results of the SPF check and the DKIM validation.

A DMARC validation checks if an incoming email corresponds to what the recipient knows about the sender. The DMARC validation is performed after the SPF check and the DKIM validation. Based on the results of the SPF check and the DKIM validation, the DMARC validation decides how to handle the email. For more information about the DMARC decision matrix, see DMARC Decision Matrix.

You can set up the DMARC validation for incoming emails of your domains. To do so, first activate the DKIM validation (see Activating DMARC validation) and then configure the advanced options (see Configuring Advanced Options for DMARC Validation).
