That is not a failure message, that is just a deferred notice:
Judging by the following lines:
It looks like the problem is on the Yahoo end - nothing you can do about it I'd guess.

Also, please do not send me your same messages via private messages. I can read them here, and so can everyone else who may be able to help or would like to refer to his in future.
