Overview

Rebuilds the full RFC 822 source of a received email so it can be ingested by Action Mailbox.

Resend's email.received webhook only carries metadata, so the message is fetched from the Received Emails API. When the API exposes a raw message download it is used as-is; otherwise the message is reconstructed as a Mail::Message from its parts, downloading each attachment through the attachments API.
