#5506 "Email outbox: a table of outgoing email and a sender that retries until accepted, for up to an hour" (milestone 501). - email_outbox (migration 0042) holds each message per recipient, its words, its state (held / pending / sending / sent / failed), attempts and the server's last answer. email_outbox_events links alert events for #5507. - core/outbox.py: enqueue; a sender task every 15 s claims what is due (SKIP LOCKED, stale claims released), sends the batch over one connection with no session held, and settles each row: - accepted -> sent; - a 5xx refusal -> failed at once with the server's words; - no connection, a timeout, a 4xx -> retried after 30 s, 1, 2, 5, 10, 15 min, the last try at the hour, then failed; - a test (retry=False) settles on its first answer. It runs on startup, so a row left by a restart goes out at boot. - notifications.smtp_open is the one place a connection is opened. - mail.message takes the html part as optional. - cleanup ages email_outbox rows on the data window. Senders move onto it in #5507 and #5508. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
