My impression at least is that valid mail from hotmail.com <http://hotmail.com/> and other Microsoft attached domains can come from essentially anywhere in Microsoft’s IP address ranges. Also, in my experience, sending any offending messages with full headers intact to j...@office365.microsoft.com <mailto:j...@office365.microsoft.com> (more likely than not the offenders are in fact Office 365 customer) and abuse@ whichever was the sending domain is as close to a useful thing to do with those.
