Yahoo reporting "No MX or A Records" and bouncing emails

FYI, I had a client report the same Yahoo error over the weekend when 
attempting to send to a working domain. Our determination was that it 
was a sender side (yahoo) issue. It did not appear that yahoo queued or 
retried the message and instead instantly (or very quickly) gave up. 
This seems atypical MTA behavior upon what could be (and likely was) a 
temporary DNS resolution error.
