Switch the bundled IP-to-country database from DB-IP Country Lite to
IPinfo Lite for greater lookup accuracy. The download URL, cached
filename, and packaged module path all move from
dbip/dbip-country-lite.mmdb to ipinfo/ipinfo_lite.mmdb.
IPinfo Lite uses a different MMDB schema (flat country_code) that is
incompatible with geoip2's Reader.country() helper, so get_ip_address_country()
now uses maxminddb directly and handles both the IPinfo schema and
the MaxMind/DBIP nested country.iso_code schema so users who drop in
their own MMDB from any of these providers continue to work.
Drop the geoip2 dependency (it was only used for the incompatible
helper) and add maxminddb as a direct dependency — it was already
installed transitively through geoip2.
Callers that imported parsedmarc.resources.dbip directly need to switch
to parsedmarc.resources.ipinfo. Old parsedmarc versions downloading
from the dbip/ GitHub raw URL will 404 and fall back to their bundled
copy — this is the documented behavior of load_ip_db().

Port DNS reliability fixes from checkdmarc 5.15.x: cap per-query UDP
timeout at min(1.0, timeout) so a single dropped datagram no longer
consumes the entire lifetime budget, scale lifetime by nameserver count
for proper failover, and add a retries kwarg that retries on
LifetimeTimeout, NoNameservers (SERVFAIL), and OSError during TCP
fallback (NXDOMAIN and NoAnswer remain non-retryable).
Thread dns_retries through the parser API and expose it via
--dns-retries / the dns_retries INI option. Centralize DNS defaults in
parsedmarc.constants and add RECOMMENDED_DNS_NAMESERVERS for opt-in
cross-provider failover.

- Auto-download psl_overrides.txt at startup (and whenever the reverse DNS
map is reloaded) via load_psl_overrides(); add local_psl_overrides_path
and psl_overrides_url config options
- Add collect_domain_info.py and detect_psl_overrides.py for bulk WHOIS/HTTP
enrichment and automatic cluster-based PSL override detection
- Block full-IPv4 reverse-DNS entries from ever entering
base_reverse_dns_map.csv, known_unknown_base_reverse_dns.txt, or
unknown_base_reverse_dns.csv, and sweep pre-existing IP entries
- Add Religion and Utilities to the allowed service_type values
- Document the full map-maintenance workflow in AGENTS.md
- Substantial expansion of base_reverse_dns_map.csv (net ~+1,000 entries)
- Add 26 tests covering the new loader, IP filter, PSL fold logic, and
cluster detection

Download the latest DB-IP Country Lite mmdb from GitHub on startup and
SIGHUP, caching it locally, with fallback to a previously cached or
bundled copy. Skipped when the offline flag is set. Adds ip_db_url
config option (PARSEDMARC_GENERAL_IP_DB_URL) to override the download
URL. Bumps version to 9.6.0.

Should have caught this on previous fix for since. the current time is used on line 2145: connection.fetch_messages(reports_folder, since=current_time)
if that code is called and it usually won't be depending upon configuration it will fail with the time format being wrong: yyyy-mm-ddThh:mm:ss.zzzzzz+00:00Z --- this removes the extra "Z" that is not needed since utc offset is already specified and becomes invalid.
- Fixed `FileNotFoundError` when using Maildir with Docker volume mounts. Python's `mailbox.Maildir(create=True)` only creates `cur/new/tmp` subdirectories when the top-level directory doesn't exist; Docker volume mounts pre-create the directory as empty, skipping subdirectory creation. parsedmarc now explicitly creates the subdirectories when `maildir_create` is enabled.
- Maildir UID mismatch no longer crashes the process. In Docker containers where volume ownership differs from the container UID, parsedmarc now logs a warning instead of raising an exception. Also handles `os.setuid` failures gracefully in containers without `CAP_SETUID`.
- Token file writes (MS Graph and Gmail) now create parent directories automatically, preventing `FileNotFoundError` when the token path points to a directory that doesn't yet exist.
- File paths from config (`token_file`, `credentials_file`, `cert_path`, `log_file`, `output`, `ip_db_path`, `maildir_path`, syslog cert paths, etc.) now expand `~` and `$VAR` references via `os.path.expanduser`/`os.path
- Fixed `FileNotFoundError` when using Maildir with Docker volume mounts. Python's `mailbox.Maildir(create=True)` only creates `cur/new/tmp` subdirectories when the top-level directory doesn't exist; Docker volume mounts pre-create the directory as empty, skipping subdirectory creation. parsedmarc now explicitly creates the subdirectories when `maildir_create` is enabled.
Fix formatting of ISO 8601 date strings for MSGraphConnection. format yyyy-dd-mmThh:MM:SS.zzzzzz+00:00 already has a timezone indicated. The extra Z is invalid in this format. specifying a "since" in config file causes msgraph to error due to invalid time stamp.
Add environment variable configuration support and update documentation
- Introduced support for configuration via environment variables using the `PARSEDMARC_{SECTION}_{KEY}` format.
- Added `PARSEDMARC_CONFIG_FILE` variable to specify the config file path.
- Enabled env-only mode for file-less Docker deployments.
- Implemented explicit read permission checks on config files.
- Updated changelog and usage documentation to reflect these changes.
### Added
- Extracted `load_reverse_dns_map()` utility function in `utils.py` for loading the reverse DNS map independently of individual IP lookups.
- SIGHUP reload now re-downloads/reloads the reverse DNS map, so changes take effect without restarting.
- Add premade OpenSearch index patterns, visualizations, and dashboards
### Changed
- When `index_prefix_domain_map` is configured, SMTP TLS reports for domains not in the map are now silently dropped instead of being output. Unlike DMARC, TLS-RPT has no DNS authorization records, so this filtering prevents processing reports for unrelated domains.
- Bump OpenSearch support to `< 4`
### Fixed
- Fixed `get_index_prefix` using wrong key (`domain` instead of `policy_domain`) for SMTP TLS reports, which prevented domain map matching from working for TLS reports.
- Domain matching in `get_index_prefix` now lowercases the domain for case-insensitive comparison.
Elasticsearch and OpenSearch now verify SSL certificates by default when `ssl = True`, even without a `cert_path`
- Added `skip_certificate_verification` option to the `elasticsearch` and `opensearch` configuration sections for consistency with `splunk_hec`
- Splunk HEC `skip_certificate_verification` now works correctly with self-signed certificates
- SMTP TLS reports no longer fail when saving to multiple output targets (e.g. Elasticsearch and OpenSearch) due to in-place mutation of the report dict
- Output client initialization errors now identify which module failed (e.g. "OpenSearch: ConnectionError..." instead of generic "Output client error")
- Enhanced error handling for output client initialization
- Better checking of `msconfig` configuration (PR #695)
- Updated `dbip-country-lite` database to version `2026-03`
- Changed - DNS query error logging level from `warning` to `debug`
* Add MS Graph certificate authentication support
* Preserve MS Graph constructor compatibility
