ATMs are limited to 420 Euro per week per account for Greek accounts. Other than the first couple of days, or so, after the capital controls went into effect (July 12), machines were always filled, though with a limit of 60 Euro per week. There was never a government-imposed limit on foreign cards, although I think that you were never allowed to get more than 200 Euro (or is it more?) per card per day. At least, that's what my bank has been doing for "safety reasons".
