Sorry,

This repeats a message sent earlier today with the subject: ssp- requirements-01 // DKIM Strict definition needed. There have been comments that notice nothing differentiates 4.1 from 4.2. This was discussed previously but not incorporated in the revision. This definition is compatible with terms used in Eric's latest draft as well.

2.  Definitions

Add:

o  DKIM Strict: the state where the domain holder believes that all
   legitimate mail purportedly from the domain are sent with a
   valid DKIM signature and that non-compliant services are avoided.

4.1.  Scenario 1: Bigbank.example.com
...
Was:
,---
|Note that for the foreseeable future, DKIM signature breakage for
|unrestricted use patterns (ie with users and especially where users
|are members of mailing lists) will likely suffer occasional damage in
|transit.  While probably not a large percentage of total traffic, the
|kind (quality) of breakage may be significant for certain usage
|patterns.  As such, this scenario defines a more limited situation
|where the risk of a legitimate piece of mail being mislabeled as
|unsigned outweights the risk of illegitimate mail being delivered in
|the eyes of the sender.

Change to:

:Note that for the foreseeable future, DKIM signature breakage for
:unrestricted use patterns (ie with users and especially where users
:are members of mailing lists) will likely suffer occasional damage in
:transit.  While probably not a large percentage of total traffic, the

:patterns.  As such, this scenario defines a more limited situation
:where the risk of a legitimate piece of mail being mislabeled as
:unsigned outweights the risk of illegitimate mail being delivered in
:the eyes of the sender.  [Rather than indicating a DKIM Signer
:Complete state, DKIM Strict would be used instead.]
