Increase the max blocked address list. I get a lot of spam and my list of 1000 blocked addresses fills up quickly. Then, I delete the whole list (one at a time! because I don't know how to remove the whole list) and have to start all over. It's a huge waste of time and makes for a lousy experience using Mail Pro. If the Mail were free, I could understand the cap at 1000, but it's not free, so it should be treated as a premium product.
