The return ISP address gives the reason away. Many, many, many, and many more than you could count, SPAM messages originate from "@hotmail.com" addresses which have been spoofed by programs which generate false return email addresses. Apple and MSN have put HotMail accounts on their alert lists and sometimes that status causes messages originating from legitimate hotmail users to be flagged as SPAM by the Apple Mail and MSN Mail programs despite any rules that are created by the receiving users. Being on the "alert lists" does not mean that the messages will all be identified as being SPAM, but that they are suspect simply for the reason of having that particular return ISP address. Legitimate users get painted with the same tar brush and we all have to live with that condition until our governments get the idea that SPAM is truly an objectionable and despicable problem and provide appropriate punishment for the senders.
