Bumps [checkdmarc](https://github.com/domainaware/checkdmarc) from 5.17.5 to 6.0.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/domainaware/checkdmarc/releases">checkdmarc's releases</a>.</em></p> <blockquote> <h2>6.0.0</h2> <p>An RFC conformance audit compared every module line-by-line against its governing specification (SPF: RFC 7208; DMARC: RFC 9989/9990; TLSRPT: RFC 8460; MTA-STS: RFC 8461; SMTP/MX: RFC 5321/7505/2181; DNSSEC: RFC 4033-4035; SOA: RFC 1035/2181; BIMI: draft-brand-indicators-14) and found 81 discrepancies, most confirmed by executing the old code. This release fixes all of them. Many fixes change validation verdicts — records the specs call valid are no longer rejected, and records they call invalid are no longer accepted — hence the major version. This release also contains everything staged for 5.18.0, which was never released.</p> <h3>Breaking changes</h3> <ul> <li>MX STARTTLS/TLS testing is now opt-in: pass <code>--check-mx-tls</code> on the CLI or <code>check_mx_tls=True</code> to <code>check_domains()</code>, <code>check_mx()</code>, or <code>get_mx_hosts()</code>. The <code>--skip-tls</code> flag and <code>skip_tls</code> parameter are still accepted but do nothing, and passing <code>skip_tls</code> emits a <code>DeprecationWarning</code>. As a result, MX host results no longer carry the <code>tls</code> and <code>starttls</code> keys, and the CSV <code>tls</code>/<code>starttls</code> columns are empty, unless TLS testing is turned on</li> <li><code>check_dnssec()</code> performs a real chain-of-trust check anchored at the parent zone's DS record instead of verifying a zone's DNSKEY against itself. A zone with no DS at its parent (including "island of security" zones) is insecure per RFC 4033 §4.3 and returns <code>False</code>; a broken zone such as dnssec-failed.org returns <code>False</code> through any resolver, where it previously returned <code>True</code> through non-validating resolvers. Bogus (SERVFAIL with DS present) is now warned about distinctly from unsigned</li> <li>Unknown and extension tags/fields now parse with a warning instead of failing validation, as each spec requires: SPF unknown modifiers (RFC 7208 §6), DMARC unknown tags (RFC 9989 §4.7), TLSRPT extension fields (RFC 8460 §3), MTA-STS extension fields and policy keys (RFC 8461 §3.2), and BIMI unknown tags (draft §4.3). An unknown field is ignored only when it fits the spec's own extension grammar; a malformed extension name or value still fails the record or policy</li> <li>A TXT record unrelated to the record type being queried is now discarded instead of failing validation, per each spec's discard rule: TLSRPT (RFC 8460 §3.1), MTA-STS (RFC 8461 §3.1), BIMI (draft §7.2), and DMARC report authorization records (RFC 9990 §4). Each query also now returns the record carrying the version tag rather than whichever TXT record the resolver listed first. When a real record sits beside the unrelated one, the unrelated record is reported as a warning; when it is the only record present, the check reports that no record exists. DMARC authorization records are discarded silently, and a wildcard authorization record that is unrelated is still an error. Callers catching <code>UnrelatedTXTRecordFoundAtTLSRPT</code> or <code>UnrelatedTXTRecordFoundAtBIMI</code> should note that those queries now raise <code>SMTPTLSReportingRecordNotFound</code> and <code>BIMIRecordNotFound</code> instead</li> <li>Records the old code wrongly accepted are now invalid: SPF records exceeding the 10-DNS-lookup limit through <code>a</code>, <code>ptr</code>, or macro-valued terms (RFC 7208 §4.6.4 — the limit was previously only enforced for some mechanism types), SPF <code>include</code> of a domain with no SPF record (permerror per RFC 7208 §5.2), MTA-STS policies missing a required key (RFC 8461 §3.2 — the check was dead code), BIMI records missing the required <code>l=</code> tag (draft §4.3), lowercase <code>v=dmarc1</code> (RFC 9989 §4.8), and an SPF qualifier on a modifier or a value on the <code>all</code> mechanism (RFC 7208 §12)</li> <li>MTA-STS and TLSRPT records are now matched case-sensitively, with no whitespace allowed around the version tag's <code>=</code>, because RFC 8461 §3.1 and RFC 8460 §3 spell those literals with the case-sensitive <code>%s</code> notation of RFC 7405. Records such as <code>V=STSv1; id=…</code>, <code>v = STSv1; id=…</code>, <code>v=STSv1; ID=…</code>, and <code>v=TLSRPTv1; RUA=…</code> parsed before and are now syntax errors. DMARC is unaffected: RFC 9989 §4.8 makes its tag names case-insensitive and allows whitespace around <code>=</code>, which this release starts honoring</li> <li>The DMARC tree walk now applies RFC 9989 §4.10.2 Organizational Domain selection (<code>psd=n</code> wins; a <code>psd=y</code> record hands off to the record one label below it, warning when none is published there; otherwise the record with the fewest labels applies) instead of stopping at the closest parent record, which selected the opposite policy in the RFC's own worked example</li> </ul> <h3>Added</h3> <ul> <li><code>--check-mx-tls</code> CLI flag and <code>check_mx_tls</code> API parameter (see breaking changes)</li> <li><code>get_mx_record_set()</code> in <code>checkdmarc.utils</code>, returning MX hosts, warnings, null MX status, and the number of MX records in the answer (the new <code>MXRecordSet</code> type), parsed from dnspython rdata instead of text splitting. The record count is what separates "no MX records at all" from "MX records that produced no usable host"</li> <li>Null MX (RFC 7505) handling: a lone <code>0 .</code> record yields an explicit "does not accept mail" warning distinct from having no MX records (which now notes the RFC 5321 §5.1 implicit MX rule); a null MX coexisting with other MX records is flagged as an RFC 7505 §3 violation instead of producing an empty-hostname host entry; a root (<code>.</code>) target with a non-zero preference, such as <code>10 .</code>, is warned about as malformed instead of becoming an empty-hostname host entry</li> <li>MX target sanity warnings: IP-address literals (RFC 5321 §5.1), hostnames failing RFC 5321 §2.3.5 label syntax, and targets that are CNAME aliases (RFC 2181 §10.3)</li> <li>DNS over HTTPS (DoH) and DNS over TLS (DoT) support through the existing <code>nameservers</code> option, matching parsedmarc ([parsedmarc PR <a href="https://redirect.github.com/domainaware/checkdmarc/issues/886">#886</a>](<a href="https://redirect.github.com/domainaware/parsedmarc/pull/886">domainaware/parsedmarc#886</a>)). Each entry picks its own transport: an IP address means plain DNS on port 53 exactly as before, an <code>https://</code> URL means DoH, and <code>tls://ip[:port][#hostname]</code> means DoT, where the port defaults to 853 and the optional <code>#hostname</code> names the server's TLS certificate identity, matching systemd-resolved's syntax. DoH queries go through a shared <code>httpx</code> client that honors the <code>HTTP_PROXY</code>/<code>HTTPS_PROXY</code>/<code>NO_PROXY</code> and <code>SSL_CERT_FILE</code>/<code>SSL_CERT_DIR</code> environment variables, so checks can run on networks that block outbound DNS but provide an HTTP proxy. The DNSSEC, DNSKEY, and TLSA checks use the configured transports too. The <code>dnspython</code> requirement is now <code>dnspython[doh]>=2.7.0</code>, and <code>httpx>=0.26.0</code> is a new direct dependency for the shared DoH client</li> </ul> <h3>Changed</h3> <ul> <li>Update the GitHub Actions used by the workflows to their latest major versions: <code>checkout</code> v7, <code>setup-python</code> v7, <code>codecov-action</code> v7, <code>upload-artifact</code> v7, <code>download-artifact</code> v8, <code>configure-pages</code> v6, <code>upload-pages-artifact</code> v5, and <code>deploy-pages</code> v5. Most now run on Node.js 24 (<code>upload-pages-artifact</code> and <code>codecov-action</code> are composite actions). The deprecated <code>codecov/test-results-action</code> is replaced by <code>codecov/codecov-action@v7</code> with <code>report_type: test_results</code>, which is the same upload it performed before; no other workflow behavior changes</li> <li>Renamed identifiers whose names misdescribed what they hold, keeping the old names as deprecated aliases where they were public API: <ul> <li><code>checkdmarc.dnssec.check_dnssec()</code> replaces <code>test_dnssec()</code>, matching every other module's <code>check_*()</code> entry point; <code>test_dnssec()</code> remains as a deprecated alias that warns</li> <li><code>get_mx_hosts()</code> takes <code>approved_mx_hostnames</code>, matching <code>check_mx()</code> and <code>check_domains()</code>; the old <code>approved_hostnames</code> keyword remains as a deprecated alias that warns</li> <li>The CLI accepts <code>--nameservers</code> as an alias for <code>-n/--nameserver</code>, and <code>--approved-ns</code>/<code>--approved-mx</code> as clearer aliases for <code>--ns</code>/<code>--mx</code></li> <li><code>MTASTSQueryResult</code>, <code>MTASTSCheckResult</code>, <code>SMTPTLSReportingQueryResult</code>, and <code>SMTPTLSReportingResult</code> replace their plural forms, matching the singular BIMI result types; the plural names remain as aliases</li> <li><code>MTA_STS_TAGS</code> and <code>SMTP_TLS_REPORTING_TAGS</code> replace the lowercase <code>mta_sts_tags</code> and <code>smtp_rpt_tags</code> constants, matching <code>BIMI_TAGS</code>; the lowercase names remain as aliases</li> </ul> </li> <li>The <code>MXHost</code> type now declares the fields MX host dicts actually carry (<code>addresses</code>, <code>dnssec</code>, <code>tlsa</code>, <code>tls</code>, <code>starttls</code> as optional keys, with <code>hostname</code> and <code>preference</code> required in a new <code>MXRecord</code> base); the declared <code>ip_addresses</code> field never existed in any produced data</li> <li>Removed unused module-level copies of the DMARC grammar internals (<code>checkdmarc.dmarc.version_tag</code>, <code>tag_value</code>, and <code>START</code>), which duplicated the private grammar class and shadow-collided with unrelated locals</li> <li>Many internal variables renamed so a name no longer changes type or meaning mid-function (split results, parse results, pyleri grammar results, joined display strings); no behavior changes</li> </ul> <h3>Removed</h3> <ul> <li>The <code>pyopenssl</code> dependency, as planned in 5.17.5. checkdmarc stopped importing pyOpenSSL in that release; the floor was kept for one release only so upgrades would also move any leftover pyOpenSSL to a version compatible with <code>cryptography</code> 50</li> </ul> <h3>Fixed</h3> <!-- raw HTML omitted --> </blockquote> <p>...
