Hotmail/MSN/Live help?

My mail server is currently being blocked by Windows/Live/Hotmail even though I am (and have been for years) a member of Microsoft's JMRP and SNDS services. Not sure what changed after years of peaceful co-existence. Could someone from Windows Live Hotmail please contact me off list?
