`parsedmarc` is a Python module and CLI utility for parsing DMARC
reports. When used with Elasticsearch and Kibana (or Splunk), it works
as a self-hosted open-source alternative to commercial DMARC report
processing services such as Agari Brand Protection, Dmarcian, OnDMARC,
ProofPoint Email Fraud Defense, and Valimail.

> [!NOTE]
> __Domain-based Message Authentication, Reporting, and Conformance__ (DMARC) is an email authentication protocol.
