Only display the "Explicitly decline BIMI participation" hint when DMARC
policy is quarantine or reject, as BIMI requires strong DMARC enforcement
to be meaningful.
Show an informational tip with a ready-to-copy declination record
(§4.3.1 of draft-brand-indicators-for-message-identification) so users
who do not intend to publish a logo can explicitly opt out and prevent
mail clients from falling back to a parent-domain record.
Parse TLS details (version, cipher, bits, cert verification) from the
Postfix Received header parenthetical and expose them per hop, rendered
as a per-hop badge in the Email Path card.
Add an x-tls Authentication-Results result: parse it when present, and
otherwise synthesize it from the inbound hop's TLS info. A negative
result (unencrypted inbound connection) applies a -10 authentication
score penalty and is shown in the Authentication card. Enable the TLS
handler in authentication_milter.
Closes: #40
Verify that the From and Return-Path domains can actually receive replies
and bounces, mirroring Fastmail's authentication_milter ReturnOK handler.
Each domain is checked for MX records, falling back to A/AAAA (implicit MX)
and then to the organizational domain, yielding a pass/warn/fail status.
Adds return_ok to DNSResults, a 10-point DNS sub-score penalty per domain
that is wholly unreachable, and a new "Return Address Reachability" card.
Compare the HELO/EHLO hostname announced by the sending server (first
Received hop) against the sender IP's PTR records, surfacing the same
signal as x-ptr/policy.ptr in Authentication-Results. Adds helo_hostname
and helo_ptr_match to DNSResults, applies a 15-point PTR sub-score
penalty on mismatch, and displays the result in a new HELO/PTR
Consistency card.
Replace RFC 7489 PSL-based org-domain lookup and RFC 9091 PSD DMARC
fallback with the DMARCbis DNS Tree Walk algorithm (max 8 queries,
8-label shortcut, TLD records require psd=y). Add parsing for the new
t= (test mode), psd= (y/n/u), and deprecated tag detection (pct, rf,
ri). Update validateDMARC to accept p=-absent records with rua= per
DMARCbis §4.7. Score t=y by downgrading effective policy one level.
Surface user-facing advisories in DmarcRecordDisplay: deprecation
warnings for pct=/rf=/ri=, test mode explanation with per-policy
impact, and PSD/org-domain boundary notices.
Implements parsing, scoring, CLI output, and UI display for the DMARC
np= tag (DMARCbis draft-ietf-dmarc-dmarcbis), which controls policy for
NXDOMAIN subdomains independently of sp=. The score deducts 15 points
from the base and awards them back when np= is absent (good default) or
its strength is equal to or stricter than the effective sp=/p= policy.
DMARC lookup now follows the full RFC 7489 §6.6.3 fallback chain: exact
From domain → organizational domain (eTLD+1 via PSL) → public suffix
domain (RFC 9091, only when psd=y is present). DNS errors abort
immediately without triggering fallback; NXDOMAIN and missing v=DMARC1
records do trigger it. The found domain is exposed in the new
DMARCRecord.domain field for reporting purposes.
Also promote getOrganizationalDomain to a package-level function so both
HeaderAnalyzer and DNSAnalyzer can share it, and fix pre-existing
rbl_test.go compilation errors and stale score expectations.
Closes: #98
Add GET /tests endpoint returning lightweight test summaries (grade,
score, domain, date) with pagination, using database-level JSON
extraction to avoid loading full report blobs. The feature can be
disabled with --disable-test-list flag. Frontend includes a new
/tests/ page with table view and a conditional "History" navbar link.

Embed rspamd-symbols.json in the binary to provide human-readable
descriptions for rspamd symbols in reports. Optionally fetch fresh
symbols from a configurable rspamd API URL (--rspamd-api-url flag),
falling back to the embedded list on error. Update the frontend to
display descriptions alongside symbol names and scores.
Use DNS records instead of authentication results to determine DKIM
presence, enabling a three-state display: passed (green), published but
invalid signature (yellow+red), or no DKIM at all (red).
Explains the two most common causes: the mail server not being
configured to verify email authentication, or a receiver hostname
mismatch with --receiver-hostname.

Move the received chain display out of BlacklistCard into EmailPathCard,
giving it its own card styling and placing it as a dedicated section on
the report page.
- Add 'skipped' to authentication result enum in OpenAPI spec
- Fix optional chaining on bimiResult.details check
- Add rbls field to AppConfig interface
- Restrict theme storage to valid 'light'/'dark' values only
- Fix null coalescing for blacklist result data
- Fix survey source to use domain instead of ip
Detect the List-Unsubscribe-Post: List-Unsubscribe=One-Click header
(RFC 8058) and expose it as the 'one-click' unsubscribe method in the
content analysis. When unsubscribe methods are present but one-click is
absent, the summary card now shows a warning nudging senders to adopt it.
