Sounds like a separate WCP document. I agree it could be nice to have something to point to when people insist that it's my fault that their DMARC rules don't match the way my mail system works. >It also strikes me as more of an exercise in enumeration of possibilities than >an actual analysis. > >Let's see. We have: > > o Illegitimate mail > o Message changed in transit, invalidating DKIM signature > o Incorrect DKIM signing > o Incorrect SPF setup > o Unintentional domain misalignment > o Improper assertion of DMARC policy Don't forget o Normal forwarding of SPF validated mail o Authorized third party senders with no access to DKIM keys Could be an interesting document.
