Am I interpreting this correctly -- that Yahoo's implementation of DMARC is broken, such that anyone using a Yahoo address to participate in a mailing list is dead in the water?
Their implementation is not 'broken'.Rather, Yahoo has made a very conscious policy decision. So the "such that" clause of your sentence is correct. That is, the effect really is what you describe. But it's the result of an informed corporate choice rather than software or operations error.
From background exchanges and Yahoo participation in the development of DMARC, I believe they fully understood the technical and operations effects of the decision.
Whether it is the 'right' choice is primarily a political debate, and I'm not commenting on that.
