Drafts were saved without In-Reply-To and References, and a draft
re-opens in compose mode, where the composer has no original message to
rebuild them from. A reply that was saved and re-opened, or sent and
brought back with Undo, therefore went out as a new conversation.
`createDraft` now stores the threading headers, the composer saves them
with every draft of a reply, and re-opening a draft carries them into
the composer for later saves and the send.
The composer took its client, identities and active account live from
the stores. Switching accounts with a draft open moved it: autosave
created the draft in the other account, and replacing the previous
save sent that account a delete for the old draft's id, which there
names an unrelated message. The composer now stays on the account it
was opened in; the other account's identities and client are ignored
until it is closed.
The quoted original in a reply or forward renders in the app document
(a shadow root), where the viewer's iframe CSP does not apply. Opening
a reply therefore loaded every remote image and background of the
original, firing the trackers the viewer had just held back.
The quote's node view now parks remote references in
`data-bulwark-remote-*` attributes for display and restores them when
edits are synced back, so the sent reply still quotes the original as
written. Remote content shows when the policy is `allow` or the sender
is trusted.
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.
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.
In the unified view each row can be shaded with its account colour
instead of carrying an account dot, behind a layout setting. Tags keep
their own generated hue on their chips.
On a shared, group or aliased mailbox every reply, reply-all and forward
went out as `identities[0]` - the account owner - whichever mailbox was
open. `autoSelectReplyIdentity` fused two behaviours: matching one of the
user's OWN identities, which never rewrites `From:`, and the domain
catch-all, which puts an address they have not configured into `From:`.
Only the first is safe for everyone, so it is now unconditional; the
rewrite stays behind the setting, which is what its description promises.
`findReplyIdentityId` already implemented that match and was referenced
only from tests.
`forward` is admitted to the match - it was excluded, so a forward from a
shared mailbox went out as the owner - but never takes the rewrite: a reply
continues a thread whose participants know the addressing, while a forward
introduces a rewritten From to a recipient the user just typed. Quick reply
matches own identities only, having no From row to show or correct a
rewrite, and now falls back to the primary's signature as the composer
does, so a shared-mailbox quick reply is still signed.
`findReplyIdentityId` now scans recipients in To, Cc, Bcc order rather than
scanning identities, and prefers an untagged identity over a differently
tagged sibling. Scanning identities let their order decide, and
`sortIdentities` puts the login's own address first - so `To: team@,
Cc: you@` replied as you, the case this is meant to fix.
Automatic selection is restricted to the active account: `composerClient`
follows the chosen identity, and a reply or forward still carries blobIds
only its own account's server can resolve. The dropdown still offers every
account's identities to pick by hand.
New messages are deliberately left gated: `composeFromAccountEmail` falls
back to `AccountEntry.email`, written once at first login, so resolving it
unconditionally would override a user-chosen default sender identity (#507).

- Background color toolbar button next to text color, using the
BackgroundColor extension from @tiptap/extension-text-style (same
textStyle-mark pattern as Color) with a 2x8 soft-tint highlighter
palette and a remove action; emitted as inline
style="background-color: …" which survives email round-trips.
- Font-size button now shows a big-A/small-A glyph (ALargeSmall) with
the active size as a small badge, replacing the plain "Aa" text that
was easy to miss.
- background_color/remove_background_color toolbar labels in all 24
locales; unit tests for apply/unset/parse/coexistence with color and
font-size on the same span.

- Pin the rich-text toolbar to the top of the composer's scroll
container (sticky) so it stays visible while editing long bodies;
the previously translucent background becomes opaque so body text
doesn't bleed through while pinned.
- Add a font-size picker to the toolbar (14/16/18/20/24/32px plus
"Default") backed by a new TipTap FontSize extension that stores
the size as an inline style on the TextStyle mark, mirroring how
@tiptap/extension-color handles colour - inline styles survive
email round-trips, and unsetting the size leaves other text-style
attributes (e.g. colour) intact.
- Add font_size / font_size_default toolbar strings to all 25
locales.

Two new extension points for third-party attachment/cloud-storage plugins
(e.g. a WebDAV/Nextcloud file browser), neither of which the plugin API
currently supports:
- attachment-actions: a new slot rendered into every attachment's hover
action row (all six render paths: beside-sender/below-header/mobile,
each in its compact and expanded-popup form), with the AttachmentInfo
(name, type, size, blobId, emailId) passed through extraProps. Lets a
plugin offer a 'save this attachment elsewhere' action next to the
existing download/preview buttons - previously the only per-attachment
hook was the read-only onAttachmentDownload observer.
- composer-attachment-source: a new slot rendered in the composer toolbar
next to the existing composer-toolbar slot, with an onAttach(upload)
callback in extraProps. Lets a plugin that has already uploaded a file to
the JMAP server itself (api.jmap.uploadBlob) - e.g. a file picked from an
external cloud storage browser - have it added to the current draft as a
real attachment. Previously there was no way for a plugin to add an
attachment to the draft at all; the closest existing mechanism
(onBeforeBlobUpload's ExternalAttachmentResult) only replaces a locally
picked file with body text/a link, it cannot add a brand-new attachment
from an external source.
Both slots follow the existing PluginSlot pattern (calendar-event-actions):
render nothing when no plugin offers the slot, so this is purely additive.
Motivating use case: the existing nextcloud-attachments community plugin
uploads local files to Nextcloud and appends a share link to the message
body - useful for large files, but there was no way for a plugin to do the
inverse (attach a file that already lives in cloud storage as a real binary
attachment, not a link) or to let attachment recipients save an incoming
attachment back out to their own cloud storage. These two slots make both
directions possible without touching plugin-store or the sandbox bridge -
existing slot/extraProps plumbing (see calendar-event-actions) already
supports arbitrary POJO props.
A message with attachments showed a paperclip and nothing else, so the
only way to reach a file was to open the message, scroll to the bottom
and find it. The list rows never had the information to do better:
EMAIL_LIST_PROPERTIES asked for hasAttachment, a boolean.
Request attachments alongside it and render the files as chips under the
preview, each one opening that file directly. Chips honour the existing
mailAttachmentAction setting, so they preview or download exactly as the
viewer's attachment list does.
Inline parts are filtered out. A single Outlook message routinely carries
half a dozen cid: signature spacers of under 200 bytes; chipping those
would bury the one file the reader actually wants. Only parts that are
neither inline nor cid-referenced, and that carry a filename, are shown —
two at a time, with the remainder collapsed into a count.
Downloads resolve the blob source from the row's own message rather than
the selected one, so they stay correct in the unified inbox where each
row can belong to a different account.
- hoist only font longhands from wrapper divs: applying the `font`
shorthand after the line's own styles would reset the font-family/
size the line declares itself; the CSSOM exposes shorthand
declarations through the longhand queries anyway
- only preventDefault on dblclick when the unlock actually ran, so a
read-only editor keeps its default double-click behaviour
Since the signature became a verbatim, non-editable atom (#476), there
was no way to edit it in the composer at all (#822) - the styling
guarantee silently cost the editability #329 had established. Keep the
atom as the default so branded signatures still survive 1:1, and let an
explicit gesture opt out: double-clicking the block dissolves it into
regular editable content at the same position. Double-clicks that land
on a link are ignored (the click is working the link), and Enter on the
selected block keeps ProseMirror's default create-paragraph-after
behaviour.
Faithfulness of the dissolved signature:
- Leaf <div> lines become paragraphs; only vertical margins the line
does not declare are reset to 0 (how a div actually renders), so
explicit spacing and indents survive. Divs carrying hr/pre and other
non-line blocks are left to the schema parse.
- Inherited styles (font, color, ...) on wrapper divs - which have no
schema node and would be dropped - are hoisted onto the generated
line paragraphs, the line's own declarations winning.
- The content is parsed as a CLOSED document via the schema DOMParser
and spliced in with one transaction; insertContentAt fits an open
slice, which can split text runs at hard breaks and turned <br>-lined
signatures into one spaced paragraph per line.
The bracketing data-signature-block markers live outside the atom and
stay put, so the identity-switch splice and the send path's
already-embedded detection keep working on unlocked content, and
switching identities re-embeds a fresh locked block. Undo restores the
atom. A translated tooltip on the block makes the gesture discoverable.
When the server refuses the draft save, the composer resets its explicit-
close flag so the unmount stash hands the text to the continue-draft slot
(#702). The close follow-up must be dropped in that case - running it
would open the new session on top of the rescue. This was the one branch
of the close guard without a test.
Opening a mailto: link while the composer held unsaved text used to
replace the session outright and drop the text on the floor. The mailto
entry point now hands a follow-up to the composer's dirty-aware close
handler, so the "Save or discard draft?" dialog runs first: save and
discard continue into the mailto draft, cancel leaves the current draft
untouched. When a failed save hands the text back to the continue-draft
slot (#702), that rescue wins and the follow-up is dropped.
