Document Delivery Failed Status

"Delivery Failure" does not get written back to the Docusign Status component in Salesforce when an envelope fails to deliver to an email address. It would be very helpful if senders could be notified in Salesforce when this happens as well as earlier than after the final bounce. We had a rep who was notified via email three days after she sent the envelope and had not idea the signer had not received the email.
