which is why ARC brings nothing new to the table. it's not that it was 
correctly signed by the originator, it's whether i trust the mangler at 
all. if i do, then i implicitly trust that they handled the dkim 
verification too. it would be a lot more productive to work on that 
trust problem than hoping a renamed dkim signature is going to somehow 
change that.
