148f4c87a9 Rename "forensic" to "failure" in docs and dashboard configs
Update documentation files (output.md, usage.md, kibana.md, splunk.md,
elasticsearch.md, index.md, example.ini) and dashboard configurations
(Grafana JSON, Kibana ndjson, Splunk XML) to use "failure" terminology
instead of "forensic", consistent with the codebase rename.

- CLI args: --forensic-* → --failure-*
- Config keys: save_forensic → save_failure, forensic_topic → failure_topic, etc.
- Index names: dmarc_forensic → dmarc_failure
- Splunk dashboard: renamed file from dmarc_forensic_dashboard.xml to dmarc_failure_dashboard.xml
- Backward-compat note preserved: "formerly known as forensic reports"

17a612df0c Add TCP and TLS transport support to syslog module (#656)
- Updated parsedmarc/syslog.py to support UDP, TCP, and TLS protocols
- Added protocol parameter with UDP as default for backward compatibility
- Implemented TLS support with CA verification and client certificate auth
- Added retry logic for TCP/TLS connections with configurable attempts and delays
- Updated parsedmarc/cli.py with new config file parsing
- Updated documentation with examples for TCP and TLS configurations

Co-authored-by: seanthegeek <44679+seanthegeek@users.noreply.github.com>

* Remove CLI arguments for syslog options, keep config-file only

Per user request, removed command-line argument options for syslog parameters.
All new syslog options (protocol, TLS settings, timeout, retry) are now only
available via configuration file, consistent with other similar options.

Co-authored-by: seanthegeek <44679+seanthegeek@users.noreply.github.com>

* Fix code review issues: remove trailing whitespace and add cert validation

- Removed trailing whitespace from syslog.py and usage.md
- Added warning when only one of certfile_path/keyfile_path is provided
- Improved error handling for incomplete TLS client certificate configuration

Co-authored-by: seanthegeek <44679+seanthegeek@users.noreply.github.com>

* Set minimum TLS version to 1.2 for enhanced security

Explicitly configured ssl_context.minimum_version = TLSVersion.TLSv1_2
to ensure only secure TLS versions are used for syslog connections.

6719a06388 Fix logging configuration not propagating to child parser processes (#646)
* Initial plan

* Fix logging configuration propagation to child parser processes

- Add _configure_logging() helper function to set up logging in child processes
- Modified cli_parse() to accept log_level and log_file parameters
- Pass current logging configuration from parent to child processes
- Logging warnings/errors from child processes now properly display

Fixes issue where logging handlers in parent process were not inherited by
child processes created via multiprocessing.Process(). Child processes now
configure their own logging with the same settings as the parent.

Tested with sample files and confirmed warnings from DNS exceptions in child
processes are now visible.

Co-authored-by: seanthegeek <44679+seanthegeek@users.noreply.github.com>

* Address code review feedback on logging configuration

- Use exact type check (type(h) is logging.StreamHandler) instead of isinstance
  to avoid confusion with FileHandler subclass
- Catch specific exceptions (IOError, OSError, PermissionError) instead of
  bare Exception when creating FileHandler
- Kept logging.ERROR as default to maintain consistency with existing behavior

# 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

# Contributing
Thanks for contributing to parsedmarc.
## Local setup
Use a virtual environment for local development.
```bash
python3 -m venv .venv
. .venv/bin/activate
python -m pip install --upgrade pip
pip install .[build]
```
## Before opening a pull request
Run the checks that match your change:
```bash
ruff check .
pytest --cov --cov-report=xml tests.py
```
If you changed documentation:
```bash
cd docs
make html
```
If you changed CLI behavior or parsing logic, it is also useful to exercise the
sample reports:
```bash
parsedmarc --debug -c ci.ini samples/aggregate/*
parsedmarc --debug -c ci.ini samples/forensic/*
```
To skip DNS lookups during tests, set:
```bash
GITHUB_ACTIONS=true
```
## Pull request guidelines
- Keep pull requests small and focused. Separate bug fixes, docs updates, and
repo-maintenance changes where practical.
- Add or update tests when behavior changes.
- Update docs when configuration or user-facing behavior changes.
- Include a short summary, the reason for the change, and the testing you ran.
- Link the related issue when there is one.
## Branch maintenance
Upstream `master` may move quickly. Before asking for review or after another PR
lands, rebase your branch onto the current upstream branch and force-push with
lease if needed:
```bash
git fetch upstream
git rebase upstream/master
git push --force-with-lease
```
## CI and coverage
GitHub Actions is the source of truth for linting, docs, and test status.
Codecov patch coverage is usually the most relevant signal for small PRs. Project
coverage can be noisier when the base comparison is stale, so interpret it in
the context of the actual diff.
## Questions
Use GitHub issues for bugs and feature requests. If you are not sure whether a
change is wanted, opening an issue first is usually the safest path.

## Performance tuning
For large mailbox imports or backfills, parsedmarc can consume a noticeable amount
of memory, especially when it runs on the same host as Elasticsearch or
OpenSearch. The following settings can reduce peak memory usage and make long
imports more predictable:
- Reduce `mailbox.batch_size` to smaller values such as `100-500` instead of
processing a very large message set at once. Smaller batches trade throughput
for lower peak memory use and less sink pressure.
- Keep `n_procs` low for mailbox-heavy runs. In practice, `1-2` workers is often
a safer starting point for large backfills than aggressive parallelism.
- Use `mailbox.since` to process reports in smaller time windows such as `1d`,
`7d`, or another interval that fits the backlog. This makes it easier to catch
up incrementally instead of loading an entire mailbox history in one run.
- Set `strip_attachment_payloads = True` when forensic reports contain large
attachments and you do not need to retain the raw payloads in the parsed
output.
- Prefer running parsedmarc separately from Elasticsearch or OpenSearch, or
reserve enough RAM for both services if they must share a host.
- For very large imports, prefer incremental supervised runs, such as a
scheduler or systemd service, over infrequent massive backfills.
These are operational tuning recommendations rather than hard requirements, but
they are often enough to avoid memory pressure and reduce failures during
high-volume mailbox processing.
## Multi-tenant support
Starting in `8.19.0`, ParseDMARC provides multi-tenant support by placing data into separate OpenSearch or Elasticsearch index prefixes. To set this up, create a YAML file that is formatted where each key is a tenant name, and the value is a list of domains related to that tenant, not including subdomains, like this:
