Conversation
With more than one domain connected, an exchange with the same counterparty and subject on two domains merged into a single conversation: none of the three thread-resolution rules carried a domain predicate, so a References match or the subject/participant fallback happily crossed the boundary. Thread resolveThreadId's lookups with the message's domain when one is known, and split any historical cross-domain threads in a migration while preserving each domain's own message chain. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
With several domains in one mailbox, the list gave no clue which identity a conversation arrived on, and there was no way to narrow the view below a whole domain — a user holding sales@ and support@ on the same domain could not separate them. Record the registered address that claimed each inbound message (emails.address_id, returned by resolveInboundRoute so routing stays a single lookup), backfill existing mail by exact recipient match, tag each list row with the receiving identity when more than one address is registered, name it on open messages, and add an address entry to the filter menu (?address=, also honoured by GET /api/mail). Catch-all deliveries keep a NULL address_id and fall back to the domain tag. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Do not infer a registered address from domain_id.
Catch-all deliveries intentionally have address_id = null. The domain fallback selects the first registered address for that domain, so a message delivered to an unknown catch-all recipient is shown with the wrong address label. Return no identity when the exact address_id lookup fails.
Proposed fix
function identity(thread: ThreadSummary): MailAddress | null {
if (addresses.length < 2) return null;
- return (- addresses.find((address) => address.id === thread.address_id) ??- addresses.find((address) => address.domain_id === thread.domain_id) ??- null- );+ return addresses.find((address) => address.id === thread.address_id) ?? null;

Persist address_id for outbound and draft messages.
sendAndStore and saveDraft resolve a registered address but do not persist its ID. Address filtering therefore excludes sent and draft messages, including trashed outbound messages. Pass the registered address ID to insertEmail and update it when an existing draft changes its sender.

Running one QuickMail with several connected domains surfaced two gaps in the combined inbox. This PR fixes both; the two commits are independent and reviewable on their own.
1. Conversations merged across domains
None of the three rules in
resolveThreadIdcarried a domain predicate, so an exchange with the same counterparty and subject on two different domains — or a forwarded message whoseReferenceschain matched — collapsed into one conversation mixing both identities.resolveThreadIdnow scopes all three lookups (explicit parent, References/In-Reply-To, subject+participant fallback) to the message'sdomain_idwhen one is known. Messages without a domain behave exactly as before.migrations/0012_domain_scoped_threads.sqlsplits any historical cross-domain thread, keeping each domain's own message chain intact (the oldest message per domain becomes that side's thread root), and adds two composite indexes the scoped lookups use.src/lib/server/threads.test.tscovers both directions: no merge across domains, normal merging within one.2. The combined inbox couldn't say which identity mail arrived on
ThreadSummaryexposeddomain_idbut nothing rendered it, and filtering stopped at whole domains — a user holdingsales@andsupport@on the same domain had no way to tell them apart or narrow to one.emails.address_idrecords the registered address that claimed each inbound message.resolveInboundRoutealready selected that row, so it now returns the id and both ingest paths (Resend webhook and Cloudflare Email worker) store it — no extra query. Catch-all deliveries keep itNULLon purpose.migrations/0013_address_identity.sqlbackfills existing inbound mail by exact recipient match (inbound rows store the routed mailbox into_addr).address_id(catch-all, pre-backfill mismatches) fall back to the domain.?address=query param thatGET /api/mailhonours too.Testing
