RFC stipulates the following:
 
"The class sub-code provides a broad classification of the status.
   The enumerated values the class are defined as:

    2.X.X   Success

       Success specifies that the DSN is reporting a positive delivery
       action.  Detail sub-codes may provide notification of
       transformations required for delivery.

    4.X.X   Persistent Transient Failure

       A persistent transient failure is one in which the message as
       sent is valid, but some temporary event prevents the successful
       sending of the message.  Sending in the future may be successful.

    5.X.X   Permanent Failure

       A permanent failure is one which is not likely to be resolved by
       resending the message in the current form.  Some change to the
       message or the destination must be made for successful delivery.
 
So, I guess we CAN make our own conclusions from the detailed reason data, but it does seem to me that the interpretation of the code by iMS sort of steps away from the RFC spec.

It seems to me that there's no real difference between the way you
should handle a "temporary" failure that goes on for days and a
"permanent" failure, especially considering the wide variety of mail
system configurations (and misconfigurations) out there.  In either
case, if you're really interested in contacting the person you have to
use a different means or try to involve the admin of the receiving
server.  I don't think most end users know or care about the distinction.
