DMARC's "job" is to mitigate direct domain abuse, nothing more and nothing less. The use of homoglyphs is a form of "spoofing". DMARC does nothing to prevent this. The use of cousin domains is a form of "spoofing". DMARC does nothing to prevent this. DMARC is very useful for what it does, but that's it. DMARC does not " flat out prevent unauthorized spoofing ".
