Adds the same "Forward as attachment" action from the message viewer's
overflow menu to the right-click context menu on a message row in the
list, right after "Forward". Reuses the handleForwardAsAttachment
handler and buildForwardAsAttachmentPayload helper introduced earlier
in this PR - no new logic, just threading the prop down EmailList ->
EmailContextMenu the same way onForward already is.
blobId is already present on list-row emails (EMAIL_LIST_PROPERTIES
includes it specifically for the existing drag-out-to-filesystem .eml
export feature), so this works without any additional fetch. The menu
item is disabled if it's ever missing, matching how other actions
degrade when their handler prop isn't supplied.
Reuses the email_viewer.forward_as_attachment translation key already
added (via a second scoped useTranslations("email_viewer") call,
matching this file's existing cross-namespace pattern for
email_viewer.color_tag) rather than adding a duplicate key under
context_menu - avoids touching all 24 locale files again.
The Pro/embedded composer-hoisting effect built its own `replyTo`
straight from `selectedEmail`, unconditionally, ignoring
`pendingDraft.replyTo`. That meant intent set by the opener - e.g.
handleForwardAsAttachment's synthetic message/rfc822 attachment -
would silently get dropped when the composer is hoisted into a Pro
tab, falling back to a normal quoted forward instead. Mirror the same
precedence the non-embedded render path already uses just below
(`pendingDraft.replyTo` wins when set).
Caught by GitHub Copilot's automated PR review.
Adds a "Forward as attachment" action to the message overflow menu
(desktop and mobile), right beside the existing "Export as .eml"
action. Opens a new forward-mode compose window with the original
message attached as a message/rfc822 file instead of quoted inline -
useful for reporting spam/phishing to an upstream gateway that expects
the raw original as an attachment (the primary motivating use case:
gateways like MxGuarddog require complete original headers, including
the full mail path, for scanning), or for preserving a message's exact
formatting/headers when forwarding.
Implementation reuses the composer's existing attachment-carry-forward
mechanism (the `attachments` useState initializer in
email-composer.tsx already carries a forwarded message's own
attachments into the new compose via `replyTo.attachments`) - this
just adds one synthetic entry representing the whole original message,
referenced by its existing blobId. No re-fetch or re-upload needed,
since JMAP blobs are account-scoped rather than per-email. The inline
quote-header step (prepareComposerQuoteHeader) is skipped, so the body
starts blank instead of quoting the original.
The core "build subject + attachment entry" logic is extracted into a
pure, unit-tested helper (lib/forward-as-attachment.ts) rather than
left inline in the already-large page component.
Adds the forward_as_attachment locale key to all 24 locales (English
text as a placeholder pending translation, following the existing
add-a-key convention) to satisfy the translations completeness test.
