Quoting Joel W. Shea via luv-talk (luv-talk@luv.asn.au):
You *might* be conflating DKIM with DMARC (and in particular its relationship with SPF)
I think you're right. Upon some review reading, my understanding is that MARC is an elaboration (expansion in scope) of DKIM (which in turn was an elaboration of DomainKeys), and DKIM implements digital signing & vetting of various SMTP headers and the body text. It doesn't attempt to validate the envelope, as does SPF.
DMARC tells the recipient what it should do when DKIM signatures don't match and/or when SPF records don't validate. It's additional to those things and sort of an expansion of ADSP. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
