A plugin opens a message as a click on a list row or on a search result
entry naming one does, also a message of a shared or group account,
reached through the login that reads it. On the mail page it opens in
place, in the Pro shell in an email tab as a message link does there;
elsewhere the tab loads the message's link, at most five times a minute.
A message no login reads, or one its account does not have, is refused
with an error the plugin sees, as is one the mail page could not open.
Needs email:read.
Stalwart does no BIMI, so sender icons were only ever favicons, which
anyone controls for any domain. The webmail server now does the
receiver side itself at /api/bimi, and avatars ask it only for
messages whose own Authentication-Results say dmarc=pass for the exact
From domain.
- `lib/bimi/`: DMARC policy check (quarantine or reject, pct=100, the
parent domain's sp and p for subdomains), the assertion record with
fallback to the parent domain, mark certificate validation (chain to
pinned DigiCert, GlobalSign and SSL.com VMC roots, BIMI key purpose,
validity, SAN, SCTs present, CRL revocation, logo from the logotype
extension), SVG Tiny PS checks and rendering to PNG, caching
- logos backed only by the DNS record show by default; the admin
setting "Require a mark certificate" (`BIMI_REQUIRE_CERTIFICATE`)
limits them to VMC and CMC backed ones
- a check mark beside the sender's name for certificate-backed logos
- avatars try contact photo, BIMI logo, plugin avatar, favicon; the
sender warning shield still wins, and logos follow the sender icons
setting and the no-third-party-traffic mode
- the two-label public suffix list moved to `lib/root-domain.ts`
SCT signatures are not verified and only the default selector is used.
Settings get a page of their own for accessibility, with presets on top
(screen reader, low vision, dyslexia, focus, keyboard and motor, motion
and seizure safe, deaf and hard of hearing) that change several options
at once and can be undone, then the options by topic, and a reset.
Text size used to be a fixed 14/16/18px on the root, which threw away
the size people set in their browser. It is now a percentage of the
browser's size, from 87.5% to 200%. Motion, contrast and transparency
follow the system by default and can be overridden either way; the
old Animations switch becomes Reduce motion. The visual options are
applied before the first paint, so the page no longer flashes at the
wrong size.
- `lib/accessibility-settings.ts`: the new settings, their allowed
values, and the code that writes them onto `<html>`
- `app/accessibility.css`: bundled fonts (Atkinson Hyperlegible Next,
Lexend, OpenDyslexic), text spacing, a focus outline that survives
Windows contrast themes, more-contrast colours on any theme, reduced
transparency, a large pointer
- admins can preset every new option but lock only shortcuts, send
confirmation and the notification duration; a lock on text size or
another reading aid works as a default
- always-light mail and toolbar labels now sync, and imports drop
values the page doesn't know
- font size and animations move off Appearance, the plain text font
off Reading; everyday settings such as conversation view and undo
send show on both their own page and Accessibility
Each impersonation handoff makes an app password on the target mailbox
that expires after 8 hours. Stalwart keeps an app password after its
expiresAt and counts it against the mailbox's limit (5 by default), and
nothing deleted the expired ones, so after five handoffs every further
one failed with "You have exceeded your quota of 5 app passwords" and the
mailbox could no longer be opened that way.
Before making a new one, the handoff now lists the mailbox's app
passwords and deletes its own expired ones, recognised by the
"Support session " description. The user's own app passwords and a
session still running are never touched. It is best effort: if the list
or the delete fails, the handoff tries to create the password as before.
