I've spent some time getting Hotmail to work within Thunderbird. One of the snags was that test messages sent to my PN address did not get through. That was until I white listed my address. Why were the incoming messages blocked prior to white listing? There was nothing strange about them ( not even Niagara was mentioned let alone you know what ).
No one has to agree with my opinion, but in the time I have left a miracle would be nice.
