The values in these tags are based on the data that is received in the Delivery Status Notification that is received by the system.  As a result, they conform to the standard descriptions that are commonly used on the Internet.  Some details on the codes that are commonly used may be found in RFC 3463.

It should be noted, however, that not all mail transfer agents use the same codes to mean the same thing, and some will deliberately use codes that do not match the standards for the purposes of SPAM prevention, so you should use these descriptions with a bit of care.
