We had the same problem. I solved it by adding an SPF entry to our DNS server: example.com. IN TXT "v=spf1 mx mx:mail.example.com -all" (mail.example.com representing our outgoing and incoming mail server). Originally, following the recommendation made by the SPF wizard at http://www.openspf.org/, we had "v=spf1 mx mx:mail.example.com ~all" (note the tilde instead of the dash), but that was apparently not good enough for hotmail. See http://www.openspf.org/SPF_Record_Syntax for an explanation of the SPF syntax.
