Looks like Yahoo! Mail have made the effort to support email standards 100%. This is excellent news, having one of the top mail clients prove their support to The Email Standards Project shows the weight this standard initiative has behind it.

I wrote about the importance of the Email Standards Project a while back. It’s great to see awareness and its popularity growing. Gmail has my emailing love at the moment, I can’t fault the service compared to its competitors, it’s fantastic! It will upset me, though, if they don’t sacrifice a little of their genius to implement the changes needed to bring them into compliance, or, at the very least give an explanation for not doing so.
