The conversation view used on phones built its own sanitizer hook that
only caught `<img src>` starting with a lowercase scheme and inline
style `url()`, and its iframe CSP always allowed http(s) images. With
remote content blocked (the default `ask` policy) uppercase schemes,
srcset, `<source>`, video posters and background attributes still
loaded, so trackers fired when a phone user opened a thread.
The view now uses the desktop viewer's `blockExternalResourcesOnNode`,
and the strict iframe CSP is shared as `emailIframeCsp()` and applied
whenever remote content is blocked, together with `no-referrer`.
A newsletter's List-Unsubscribe `mailto:` was sent from the user's own
account as written: every `to=` field became a recipient, and subject
and body were the sender's choice. The confirmation said only
"Unsubscribe from this sender?", so one click could mail
"I resign" to someone's boss and HR.
The unsubscribe now goes to the single address in the URL (a list of
addresses is refused and `to=` is ignored), the subject is kept on one
line and both subject and body are capped. Both confirmations show the
recipient, subject and body before anything is sent.
Attachment thumbnails were object URLs typed with the sender's MIME
type. Object URLs share the webmail origin, so an `image/svg+xml`
attachment opened from its thumbnail ("Open image in new tab", or
dragged to the tab strip) ran the sender's script as the webmail in
Chromium and Firefox. The drag-out URL and Files thumbnails had the
same shape.
`fetchBlobAsObjectUrl` now re-types every blob to an inert type, and
image thumbnails in mail and Files go through `imageBlobUrl`, which
hands an SVG over as a `data:` URL: it still renders in the `<img>`,
but opened on its own it gets an opaque origin.
The re-sync effect depended on pushStatus.kind, so its own
setPushStatus({ kind: 'busy' }) re-fired the effect, whose cleanup
cancelled the in-flight enableWebPush - the push row then sat on
"Working…" forever and never updated the filter. Depend only on the
setting flip; read client/relay/status live from the recreated closure.
Flipping the setting only wrote to the store; the server-side JMAP push
filter stayed stale until the next app launch ran resyncWebPush. When push
is already enabled on the device, re-run enableWebPush on change so the
toggle takes effect without a restart.
The composer uploaded any file and learned about `maxSizeUpload` (per
blob) or `maxSizeAttachmentsPerEmail` (per message) only from a failed
upload or a failed send. Files over the per-file limit, and files that
would push the message past the per-message limit, are now skipped
with a message naming the limit. The limits come from the account the
message is composed in.
From 0.16.21 Stalwart fails the whole CalendarEvent/set with
`forbidden` when the account may not send scheduling messages, so an
event with attendees was not saved at all and the calendar showed only
"Failed to save event".
Such a refusal now surfaces as SchedulingDeniedError, and the calendar
names the server's reason and offers to save the event without sending
the invitations.
Bulwark asks for a 90-day push subscription, but Stalwart clamps
`expires` to 7 days. The background renewal ran once per page load,
so a tab or installed app left open for more than a week let the
subscription lapse and notifications stopped without a hint.
The renewal now runs at most once a day instead of once per load, and
also when the tab comes back to the foreground.
Stalwart refuses a VacationResponse subject of 512 bytes or more and a
text or HTML body of 2048 bytes or more, answering only "Field could
not be set." The limit counts bytes, so 1030 "ä" already exceed it,
and the HTML from the rich-text editor reaches it quickly. The save
failed with a generic error.
On Stalwart the vacation settings now check the subject and the text
and HTML that would be sent, and name the limit instead of saving.
From 0.16.6 Stalwart refuses FileNode names with `/<>:"\|?*` or a
reserved name such as `CON` ("Name contains a forbidden character."),
and publishes the rules as `forbiddenNameChars` / `forbiddenNodeNames`.
Bulwark did not read them: the error showed up only after an upload had
started, and it aborted the rest of a multi-file or folder upload.
- new folder, new text file and rename now say which characters or
names the server does not allow, before sending anything
- uploads store an accepted variant instead: forbidden characters
become `_` and a reserved name gets `_` appended
MIME types over 30 characters (most Office formats) were always stored
as `application/octet-stream`, because Stalwart before 0.16.6 refuses
them. From 0.16.6 the limit is 255, so the real type is kept there.
Stalwart advertises `maxDelayedSend` as a fixed 30 days, but its MTA
rejects any hold beyond `futureRelease`, 7 days by default. Scheduling
a message 8 to 30 days ahead passed the picker and then failed with
"501 5.5.4 Requested hold time exceeds maximum of 604800 seconds".
On Stalwart the advertised 30 days now counts as 7. When a submission
is still rejected for its hold time, the limit from the error message
replaces it for the session, and the composer shows the translated
"later than the server allows" message instead of the raw SMTP reply.
Bulwark read the live display name (#900) and the account profile with
`x:Account/get`, which Stalwart only allows for admins. Every other
user got `forbidden`, so the settings page showed no name and the
identity kept the stale snapshot. The name now comes from
`x:AccountSettings/get`, the account's own settings object; aliases
and quota still use `x:Account/get` where it is permitted.
With TOTP on, Stalwart requires the current code for a password change
and for switching TOTP off ("Current OTP code is required"). Neither
dialog asked for it. Both now do, and the password change sends it as
the `otpAuth/otpCode` patch, because a whole `otpAuth` object would
reset `otpUrl` and turn TOTP off.
Saving the display name also ignored a `notUpdated` answer and showed
success.
Stalwart only moves spam to Junk when nothing else decided where the
message goes. Any Bulwark rule that moved or copied mail to a folder
therefore delivered spam there too, e.g. a "subject contains invoice"
rule collected phishing. From 0.16.22 this also applies to the "Keep"
allow-list action, which older versions still send to Junk.
Move and copy rules now add
`not spamtest :percent :value "ge" :comparator "i;ascii-numeric" "50"`
to their condition when the server supports `spamtestplus` and
`relational`. 50 % is Stalwart's spam threshold on the graded scale
(0.16.19+), and older versions report 0 or 100. A new per-rule option
"Also move messages marked as spam" drops the guard, and "Keep" rules
are left unguarded as the explicit allow-list.
The Sieve generator wrote actions in the order they were picked in the
rule editor. `fileinto` stores the flags set at that moment, so "mark
read", "star" or "add label" placed after a move never reached the
moved message. Flag actions are now emitted first.
Moves and copies also targeted the folder by path only. Renaming the
folder silently sent the rule's mail to Inbox. Rules now store the
folder id and emit `fileinto :mailboxid "<id>" "<path>"` when the
server lists `mailboxid` (declaring `mailbox` too, which Stalwart
requires), with the path as the fallback. Saving a rule refreshes the
path from the id, so existing rules pick up the id on their next save.
Forward actions get a "Keep a copy" option (`redirect :copy`), and the
editor honours the server's `maxNumberRedirects` (1 on Stalwart):
forward is disabled once the limit is used up, with a hint when
existing rules already exceed it, because the server skips extra
redirects without telling anyone.
Stalwart allows one active Sieve script and turns the auto-reply on by
activating its own `vacation` script. Turning the auto-reply on switched
every Bulwark filter off (including junk and folder rules), and saving
any filter switched the auto-reply off again.
When the vacation script takes over from an existing filters script,
the filters script is now re-activated with
`include :personal :optional "vacation"`, so the server-built reply
(with its date window and HTML body) runs from there. Turning the
auto-reply off drops the include again. A filters save while the
vacation script is active keeps it through the same include, and the
vacation settings read the include as "on", because
VacationResponse.isEnabled reports false in that state.
Clients that only look at VacationResponse (Stalwart's web UI, phones)
still show the auto-reply as off while the include is active.
JMAP thread ids are only unique within their account - Stalwart hands out
per-account counters such as "b" - so the cross-account views merged
unrelated conversations that happened to share an id, and every
client-side thread map (expansion, cache, loading flag, counts,
virtualizer key) mixed them up the same way.
Give ThreadGroup an account-scoped `threadKey` derived from the email's
source stamps and key grouping and all thread state by it. `threadId`
stays the raw id for Thread/get, which #281 already routes to the owning
account. fetchThreadEmailCounts now asks each source account for its own
threads instead of one client for every id. Single-account views carry no
stamps, so their key is the bare id and nothing changes there.
