Introduction

What is opendmarc
opendmarc is:
Domain-based Message Authentication, Reporting and Conformance (DMARC), builds on the successes of technologies such as DomainKeys Identified Mail (DKIM) and the Sender Policy Framework (SPF) to create an infrastructure that enforces policy on domain names that are visible to end users, and creates a feedback framework for identifying and tracking fraudulent use of domain names in email. It uses OpenDBX as an interface layer to various SQL back ends.
It provides the following new capabilities:
A binding between the domain name seen in the From: field of a message and one or both of the domain names verified by DKIM and SPF;
The capability to request that receivers enforce strict message authentication policy published by the author; and Comprehensive reporting, both forensic and aggregate, regarding suspect messages.
This package contains the OpenDMARC mail filter (Milter) for plugging into Milter-aware MTAs. It implements support for both message reject and DMARC failure reporting.
