Both mids and watermark fields are used to determine which messages were delivered. watermark is always present and mids is sometimes present. mids provides delivery receipts on a per-message basis but may not be present (due to backward compatibility reasons with older Messenger clients). watermark is always present and is a timestamp indicating that all messages with a timestamp before watermark were delivered.
