domainaware/parsedmarc 9.4.0

on GitHub

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.
