+1 In other words SSP-MUST means "if you do SSP you MUST get it right". An example from the also voluntary SPF: If the receiver aborts SPF-evaluation for his own private reasons (no TempError, let alone PermError) it's fine, but then this receiver shouldn't add a dubious Received-SPF: NONE (or even NEUTRAL) trace header field, because that would be a lie.
