Re: [ietf-dkim] NEW ISSUE: Limit the application of SSP to unsigned messages

Sure thing!

The purpose of SSP is to detect unauthorized domain use. This can not be achieved if the spec assumes that a signature from just anybody what-so-ever is OK. So, the engineering rationale for rejecting your idea is that accepting it would mean a complete defeat of the purpose.

Arvel,

It would help to have some engineering rationale and market demand commentary to flesh our a call for "utter" rejection.

All text that causes SSP to be applied to an already-signed message needs to be removed.

-1.  That simply has to be utterly rejected.

A DKIM signature is a statement of responsibility. When a signature is present, an organization has taken responsibility for the message.

That's fine for DKIM-Base.  We're discussing SSP though.
