I have limited internet here where I am right now, at home this wouldn't be an issue, but abroad it is. My stock email app on OS X Lion is constantly re-downloading the same emails over and over and over again. That gets pretty bandwidth dependant when its downloading 1500 emails over and over again. Is there a setting I need to check where it only downloads new emails in my inbox and not the thousands in various folders? It only needs to download those once, why is it downloading them over and over if they are already there?
