* Fix mbox-run progress display and document n_procs scope (#147) An mbox-only run showed a misleading, permanently-stuck `0it` progress bar: the CLI's tqdm bar only tracks report files passed directly as arguments (mbox paths are split out first), and per-message mbox progress is only logged at INFO, which --silent / config-file runs hide. The empty bar is no longer created when there are no direct file arguments, and get_dmarc_reports_from_mbox() now wraps its message loop in a tqdm bar that auto-disables on non-TTY output (tqdm's disable=None), so interactive mbox imports show real per-message progress while tests, cron jobs, and piped runs stay clean. Also documents that n_procs parallel parsing applies only to report files passed directly on the command line — messages from mbox files and mailbox connections (IMAP, Microsoft Graph, Gmail API, Maildir) are always processed sequentially — and fixes the pre-existing "Number of process" typo in that entry. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Gate the CLI progress bar on stderr, where tqdm renders it Addresses Copilot review feedback on #846: tqdm writes to stderr by default, but the guard checked sys.stdout.isatty(), so a run with stderr redirected to a log file would write bar escapes into the log, and a run with stdout redirected (e.g. piping the JSON output) hid the bar even though stderr could display it. This also matches the mbox bar's disable=None auto-check, which keys off tqdm's own output stream.

parsedmarc
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.
Sponsors
This project is maintained by one developer. Please consider sponsoring my work if you or your organization benefit from it.
Features
- Parses aggregate/rua DMARC reports: the legacy draft and 1.0 schemas (RFC 7489) and the new RFC 9990 schema for the final DMARC standard (RFC 9989)
- Parses failure/ruf DMARC reports (RFC 6591 and RFC 9991; formerly called forensic reports)
- Parses reports from SMTP TLS Reporting (TLS-RPT, RFC 8460)
- Can parse reports from an inbox over IMAP, Microsoft Graph, or Gmail API
- Transparently handles gzip or zip compressed reports
- Consistent data structures
- Simple JSON and/or CSV output
- Optionally email the results
- Optionally send the results to Elasticsearch, OpenSearch, Splunk, or PostgreSQL, for use with premade dashboards
- Optionally send the results to Apache Kafka, Amazon S3, Azure Log Analytics (Microsoft Sentinel), a Graylog (GELF) endpoint, a syslog server, or an HTTP webhook
