Add an optional vertical column beside delete that allows you to select an individual sender to automatically block and delete an individual sender. Day after day I keep getting spam from the same senders. It's very time consuming to keep going in and deleting these emails several times each day. mailwasher identifies them, but you still have to go through each to make sure that it's correct and you don't want to turn on the global auto delete function as it catches some good emails too whichd ned correct with that mode. You might consider also having the option of automatically bouncing these specifically identified senders.
I've used your product since it's inception and wouldn't be without it. Both it and the service are outstanding.
