Local mailbox

This is a file on the machine running the app (or a named Vercel Blob when BLOB_READ_WRITE_TOKEN is set), not an internet mailbox. Local v1 writes leftover verification codes here, and watchlist digest copies (preview/test/scheduled send) land here too. Internet SMTP for digests is separate and only runs when ALERT_EMAIL_SMTP_HOST and ALERT_EMAIL_FROM are set. Do not treat this as a production mail service.

No local messages yet. Registration is closed; leftover verification codes and watchlist digest copies would appear here.
