Lets just say Yahoo starts blocking because of unusual traffic. Yahoo will keep telling "me" to try again later. In the mean time, new emails to be sent arrives and we never get the change to get unblocked.
So postfix gets the next yahoo recipient and try to deliver without considering that yahoo does not want us to keep trying for a while.
This is just an example. We don't have problem delivering to Yahoo, but to smaller providers.
