a4ac5accd2 Add TypedDict definitions to replace dict[str, Any] for better typing
- Added comprehensive TypedDict definitions for all major data structures
- IPAddressInfo, EmailAddress, ReverseDNSService in utils.py
- AggregateReport, ForensicReport, SMTPTLSReport and related types in __init__.py
- Updated function signatures throughout codebase to use TypedDict types
- Reduced dict[str, Any] usage from 50+ to 11 (remaining are legitimate generic cases)
- All tests pass successfully

# AGENTS.md
This file provides guidance to AI agents when working with code in this repository.
## Project Overview
parsedmarc is a Python module and CLI utility for parsing DMARC aggregate (RUA), failure/forensic (RUF), and SMTP TLS reports. It supports both RFC 7489 and DMARCbis (draft-ietf-dmarc-dmarcbis-41, draft-ietf-dmarc-aggregate-reporting-32, draft-ietf-dmarc-failure-reporting-24) report formats. It reads reports from IMAP, Microsoft Graph, Gmail API, Maildir, mbox files, or direct file paths, and outputs to JSON/CSV, Elasticsearch, OpenSearch, Splunk, Kafka, S3, Azure Log Analytics, syslog, or webhooks.
## Common Commands
```bash
# Install with dev/build dependencies
pip install .[build]
# Run all tests with coverage
pytest --cov --cov-report=xml tests.py
# Run a single test
pytest tests.py::Test::testAggregateSamples
# Lint and format
ruff check .
ruff format .
# Test CLI with sample reports
parsedmarc --debug -c ci.ini samples/aggregate/*
parsedmarc --debug -c ci.ini samples/failure/*
# Build docs
cd docs && make html
# Build distribution
hatch build
```
To skip DNS lookups during testing, set `GITHUB_ACTIONS=true`.
## Architecture
**Data flow:** Input sources → CLI (`cli.py:_main`) → Parse (`__init__.py`) → Enrich (DNS/GeoIP via `utils.py`) → Output integrations
### Key modules
- `parsedmarc/__init__.py` — Core parsing logic. Main functions: `parse_report_file()`, `parse_report_email()`, `parse_aggregate_report_xml()`, `parse_failure_report()`, `parse_smtp_tls_report_json()`, `get_dmarc_reports_from_mailbox()`, `watch_inbox()`. Legacy aliases (`parse_forensic_report`, etc.) are preserved for backward compatibility.
- `parsedmarc/cli.py` — CLI entry point (`_main`), config file parsing, output orchestration. Accepts both old (`save_forensic`, `forensic_topic`) and new (`save_failure`, `failure_topic`) config keys.
- `parsedmarc/types.py` — TypedDict definitions for all report types (`AggregateReport`, `FailureReport`, `SMTPTLSReport`, `ParsingResults`). Legacy alias `ForensicReport = FailureReport` preserved.
- `parsedmarc/utils.py` — IP/DNS/GeoIP enrichment, base64 decoding, compression handling
- `parsedmarc/mail/` — Polymorphic mail connections: `IMAPConnection`, `GmailConnection`, `MSGraphConnection`, `MaildirConnection`
- `parsedmarc/{elastic,opensearch,splunk,kafkaclient,loganalytics,syslog,s3,webhook,gelf}.py` — Output integrations
### Report type system
`ReportType = Literal["aggregate", "failure", "smtp_tls"]`. Exception hierarchy: `ParserError``InvalidDMARCReport``InvalidAggregateReport`/`InvalidFailureReport`, and `InvalidSMTPTLSReport`. Legacy alias `InvalidForensicReport = InvalidFailureReport` preserved.
### DMARCbis support
Aggregate reports support both RFC 7489 and DMARCbis formats. DMARCbis adds fields: `np` (non-existent subdomain policy), `testing` (replaces `pct`), `discovery_method` (`psl`/`treewalk`), `generator` (report metadata), and `human_result` (DKIM/SPF auth results). `pct` and `fo` default to `None` when absent (DMARCbis drops these). Namespaced XML is handled automatically.
### Caching
IP address info cached for 4 hours, seen aggregate report IDs cached for 1 hour (via `ExpiringDict`).
## Code Style
- Ruff for formatting and linting (configured in `.vscode/settings.json`)
- TypedDict for structured data, type hints throughout
- Python ≥3.10 required
- Tests are in a single `tests.py` file using unittest; sample reports live in `samples/`

# Changelog
## 10.0.0
### Enhancements
#### Support for DMARCbis reports
New fields from the XSD schema, added to types, parsing, CSV output, and Elasticsearch/OpenSearch mappings:
- `np` — non-existent subdomain policy (`none`/`quarantine`/`reject`)
- `testing` — testing mode flag (`n`/`y`), replaces RFC7489 `pct`
- `discovery_method` — policy discovery method (`psl`/`treewalk`)
- `generator` — report generator software identifier (metadata)
- `human_result` — optional descriptive text on DKIM/SPF auth results
Backwards compatibility to RFC7489 is maintained.
### Breaking changes
#### Forensic reports have been renamed to failure reports
Forensic reports have been renamed to failure reports throughout the project to reflect the proper naming of the reports since RFC7489.
- **Core**: `types.py`, `__init__.py``ForensicReport``FailureReport`, `parse_forensic_report``parse_failure_report`, report type `"failure"`
- **Output modules**: `elastic.py`, `opensearch.py`, `splunk.py`, `kafkaclient.py`, `syslog.py`, `gelf.py`, `webhook.py`, `loganalytics.py`, `s3.py`
- **CLI**: `cli.py` — args, config keys, index names (`dmarc_failure`)
- **Docs & dashboards**: all markdown, Grafana JSON, Kibana NDJSON, Splunk XML
##### Backward compatibility
- Old function/type names preserved as aliases: `parse_forensic_report = parse_failure_report`, `ForensicReport = FailureReport`, etc.
- CLI config accepts both old (`save_forensic`, `forensic_topic`) and new keys (`save_failure`, `failure_topic`)
- RFC 7489 reports parse with `None` for DMARCbis-only fields
- **Updated dashboards with queries are backward compatible**: queries match data indexed under both old (`dmarc_forensic*` / `dmarc:forensic`) and new (`dmarc_failure*` / `dmarc:failure`) names, so dashboards show data from before and after the rename:
- **Kibana**: Index pattern uses `dmarc_f*` to match both `dmarc_forensic*` and `dmarc_failure*`
- **Splunk**: Base search queries `(sourcetype="dmarc:failure" OR sourcetype="dmarc:forensic")`
- **Elasticsearch/OpenSearch**: Duplicate-check searches query across both `dmarc_failure*` and `dmarc_forensic*` index patterns
## 9.1.1
### Fixes
- Fix the use of Elasticsearch and OpenSearch API keys (PR #660 fixes issue #653)
### Changes
- Drop support for Python 3.9 (PR #661)
## 9.1.0
## Enhancements
- Add TCP and TLS support for syslog output. (#656)
- Skip DNS lookups in GitHub Actions to prevent DNS timeouts during tests timeouts. (#657)
- Remove microseconds from DMARC aggregate report time ranges before parsing them.
## 9.0.10
- Support Python 3.14+
## 9.0.9
### Fixes
- Validate that a string is base64-encoded before trying to base64 decode it. (PRs #648 and #649)
## 9.0.8
### Fixes
- Fix logging configuration not propagating to child parser processes (#646).
- Update `mailsuite` dependency to `?=1.11.1` to solve issues with iCloud IMAP (#493).
## 9.0.7
## Fixes
- Fix IMAP `since` option (#PR 645 closes issues #581 and #643).
## 9.0.6
### Fixes
- Fix #638.
- Fix/clarify report extraction and parsing behavior for multiple input types (bytes, base64 strings, and file-like objects).
- Fix type mismatches that could cause runtime issues in SMTP emailing and CLI option handling.
### Improvements
- Improve type hints across the library (Pylance/Pyright friendliness) and reduce false-positive linter errors.
- Emails in Microsoft 365 are now marked read as they are read. This provides constancy with other mailbox types, and gives you a indication of when emails are being read as they are processed in batches. (Close #625)
### Compatibility / Dependencies
- Set Python requirement to `>=3.9,<3.14`.
- Bump `mailsuite` requirement to `>=1.11.0`.
## 9.0.5
## Fixes
