## What are DMARC and OpenDMARC?
|
|
|
|
|
|
|
|
|
|
Quote from [DMARC.org](https://dmarc.org):
|
|
|
|
|
|
|
|
|
|
> DMARC, which stands for __Domain-based Message Authentication, Reporting
|
|
|
|
|
> & Conformance__, is an email authentication, policy, and reporting protocol.
|
|
|
|
|
> It builds on the widely deployed SPF and DKIM protocols, adding linkage to
|
|
|
|
|
> the author (`From:`) domain name, published policies for recipient handling
|
|
|
|
|
> of authentication failures, and reporting from receivers to senders, to
|
|
|
|
|
> improve and monitor protection of the domain from fraudulent email.
