Research direction
Start by reproducing the failure through /rails/conductor/action_mailbox/inbound_emails/ and follow the Error performing ActionMailbox::RoutingJob path for inbound .eml files. Inspect the Cloudinary Active Storage integration and verify that all existing inbound emails can be fetched without HTTP 404 responses.
