* Import optional mailbox connections lazily in parsedmarc.mail

* Fix docstring grammar

* Cover the lazy-import guards with tests and harden the AuthMethod placeholder

Maintainer follow-up to the review of #884:

- Add tests/test_mail.py: a sys.meta_path blocker simulates installs
  without the gmail/msgraph stacks, exercising both except branches.
  CI always has the extras installed, so without a simulated absence
  the guarded paths would never execute and the blocking codecov patch
  gate would fail. Includes isolation-safe purge/restore of sys.modules
  so test ordering cannot leak placeholder state into other suites.
- Replace the AuthMethod = None sentinel with a placeholder that raises
  the msgraph extra's ImportError on non-dunder attribute access,
  iteration, call, and subscript (every Enum usage shape), instead of
  surfacing cryptic NoneType AttributeError/TypeError.
- Raise a fresh ImportError chained to the stored original in the
  connection placeholders, so repeated constructions do not keep
  appending frames to one shared exception object's traceback.

A screenshot of DMARC summary charts in Kibana

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.

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
