Mail accounts falling offline

yes I've had this same problem since MobileMe changed to iCloud everytime you go to check mail i've got the triangle with explanation mark on my email accounts and when i click get new mail nothing happens so i have to quit mail and restart it ..getting to be a pain in the backside...

Seriously, can we not find a solution to this? I have searched everywhere and closing Mail then re-opening it is the ONLY way to fix this problem? Yes, it works, but someone should have discovered a fix by now! This is a pain in MY backside as well....
