## What it is
parsedmarc is a Python module and CLI utility for parsing aggregate (rua), failure (ruf), and SMTP TLS reporting email authentication reports. Paired with Elasticsearch/Kibana, OpenSearch/Grafana, or Splunk, it serves as a self-hosted alternative to commercial DMARC report processing services.

## Use cases
- parse DMARC aggregate reports from an IMAP inbox
- self-hosted DMARC report processing alternative to Dmarcian or Valimail
- analyze SPF and DKIM authentication results for my domain
- process SMTP TLS-RPT reports
- export DMARC reports to Elasticsearch or Splunk dashboards
- convert DMARC XML reports to JSON or CSV

## When to choose
- you need to monitor DMARC compliance for domains you control
- you want a self-hosted, open-source alternative to paid DMARC services
- you already run Elasticsearch, OpenSearch, or Splunk for log analytics
- you need to parse reports from IMAP, Microsoft Graph, or Gmail API inboxes

## When to avoid
- you want a fully managed DMARC service with no infrastructure to run
- you need a GUI-only tool without any setup of dashboards or storage backends
- your environment requires Python versions older than 3.10
