Notifications API questions

I hope someone could help me with the following:
 
- On the arrival event for a non-delivered job there is a 3 digit code. Do we have a reference of these codes. 511 seems to be an invalid email addres
- For a successful delivery – i.e. the email is in the customer inbox – is there a way in the response to identify thi
 
- the response does not show the email address. How do I get the email address?

I have attached the XML with the response, thanks!

  • The DSN definitions are largely based on RFC 1893.

    There is no reliable way to determine that an email has made it to the recipient's inbox. We will return (in JobDeliveryStatus or JobDetail) any DSN information we have received, and there are "success" DSN definitions (2.x.x), but recipient systems often do not provide these DSNs. We also provide an "HTML open tracking" feature, but that normally is only related to an email being opened (rather than just received), and as links are sometimes either blocked or pre-screened, that is not entirely reliable either.

    The missing destination address is a problem certain customer accounts are currently experiencing. The problem is under investigation and should be resolved presently.
