Technical Summary

   This brief document corrects an error in RFC 5451 regarding 
   one Email Authentication Result Name (see RFC Editor Erratum 
   #2617).  Namely, the name "hardfail" is incorrect, and the name
   "fail" is correct (and is used in all existing implementations). 
   As far as can be determined, all implementations of Sender 
   Policy Framework (SPF) use "fail" instead of "hardfail", as 
   specified in Section 2.5.4 of RFC 4408.  The same is true of 
   Sender-ID (see Section 5.3 of RFC 4406).  The error in RFC 
   5451 was not caught during review of that specification.   
   Although in practice the error has not yet caused confusion
   among implementers, it is best to correct the error in order to
   forestall possible interoperability problems.

Document Quality

   Existing implementations use "fail" (RFC 4406, RFC 4408)
   instead of "hardfail" (RFC 5451), so there are implementations
   of the correction described in this specification.  This document
   simply corrects the error in RFC 5451 and does define any new 
   protocol.

   This correction was discussed on the apps-discuss@ietf.org
   and spfbis@ietf.org lists.  Some people thought it might be 
   appropriate to correct the error if and when the SPFBIS WG,
   whereas others thought it would be better to correct this simple
   error without opening up discussion of RFC 5451 more generally
   (and thus possibly delaying the fix).  There was agreement that
   correcting error sooner rather than later would be preferable.
