Gets the string description of the status and the dot-numeric status code.
A string value with the description of the status and the dot-numeric status code taken from "Status" DSN field.
The per-recipient Status field contains a transport-independent status code which indicates the delivery status of the message to that recipient. This field MUST be present for each delivery attempt which is described by a DSN.
Status codes thus consist of three numerical fields separated by dot ("."). The first sub-field indicates whether the delivery attempt was successful (2 = success, 4 = persistent temporary failure, 5 = permanent failure). The second sub-field indicates the probable source of any delivery anomalies, and the third sub-field denotes a precise error condition, if known.
In this example, DSN field is:
Status: 5.1.1
The return value is marked bold.
