This is the first I've heard of this issue, but it doesn't surprise me at all.
Basically, Yahoo insists that their own mail servers are the only ones that can originate the message with @yahoo.com domain in the From header. Not Return-Path, Not the envelope sender, but exactly the From header in the message itself. If this practice gets adopted by more organizations, I don't know how else could this problem be solved.
