Systems and methods for dynamic DMARC enforcement

A system for dynamic Domain-based Message Authentication, Reporting, and Conformance (DMARC) enforcement, the system comprising:

• a processor;
• a non-transitory computer-readable medium;
• and
• stored instructions translatable by the processor for:
• receiving an electronic mail (email) message;
• obtaining an originating email domain from the email message;
• responsive to the email message failing authentication, preparing and sending a query to a dynamic DMARC module, the query containing the originating email domain, wherein the dynamic DMARC module is adapted for determining whether any DMARC local policy override published from a source system is applicable to the originating email domain;
• receiving a response from the dynamic DMARC module, the response containing a DMARC local policy override that is published from the source system and that is associated with the originating email domain;
• and
• dynamically overriding a DMARC decision on the email message with the DMARC local policy override associated with the originating email domain published from the source system, wherein the dynamic overriding results in the email message which failed DMARC being delivered.

A computer program product for dynamic Domain-based Message Authentication, Reporting, and Conformance (DMARC) enforcement, the computer program product comprising a non-transitory computer-readable medium storing instructions translatable by a processor to perform:

• receiving an electronic mail (email) message;
• obtaining an originating email domain from the email message;
• responsive to the email message failing authentication, preparing and sending a query to a dynamic DMARC module, the query containing the originating email domain, wherein the dynamic DMARC module is adapted for determining whether any DMARC local policy override published from a source system is applicable to the originating email domain;
• receiving a response from the dynamic DMARC module, the response containing a DMARC local policy override that is published from the source system and that is associated with the originating email domain;
• and
• dynamically overriding a DMARC decision on the email message with the DMARC local policy override associated with the originating email domain published from the source system, wherein the dynamic overriding results in the email message which failed DMARC being delivered.
