Run into following. Mail may or may not be declared spam or even blacklisted , does not matter if the sender is in the friendlist. Mail from family will disappear at random, a business will send me an order confimation but the next email (within minutes) from the same sender will end up blacklisted. I stopped using MW Pro because I lose too much time going through the Recycle Bin looking for missing emails.
Recover is no option even with the throttle at 9999. Btw The feedback popup that shows when uninstalling MW Pro crashes if you enter feedback.
