All we can say is that there's a 270 minute gap between it arriving at
Yahoo and it being accepted for delivery by LiveMail.  It could be that
Yahoo sits on it for all that time before submitting it but it could
also be that Livemail temporarily rejects it once or twice before
finally accepting it; there is no way to tell from the headers because
they are only updated at each successful stage.

If you want to be sure, you need to submit the message IDs to mail admin
staff at Yahoo and Livemail so they can check logs.  If they're willing,
that is.
