Hotmail support "would not tell me why my domain was being flagged for spam, and when asked what the possible solutions were I was told I could sign up for 3rd party accreditation through Sender Score Certified (at a cost of $400USD start up, and $1000USD each year) who maintain the only whitelist service Hotmail use, and was also advised I could try tightening my SPF policy.

SenderID technology which Microsoft had championed (and Hotmail use) as another anti spam technology was in fact highly incompatible with SPF policies. [and they knew it]
