I think they have turned some knobs recently (or rather, they 
continuously do). Yesterday's soft reject (i.e. mail ending up in the 
spam folder) became a hard reject. I guess it's possible to argue both 
ways - at least the soft reject could be trained not to categorise real 
mail as spam. With a hard reject that problem is shifted entirely to the 
sender.
