So after testing just now with a Yahoo! Mail account myself, it
appears that Yahoo! puts their little "Signed by DomainKeys" icon on
an incoming message that is signed with DomainKeys, but doesn't put
the icon there (or do anything special in the user interface) if it's
only signed with DKIM.

Again, I have zero data on deliverability comparison, but the fact
that Yahoo! would display an icon (whose intent is clearly to increase
the recipient's trust of a message) only with DK and not with DKIM is
mind-boggling! Are they just being stubborn about their intellectual
property rights around DomainKeys vs. DKIM?
