Hi, I've tested it on our beta environnement and it seems to work.
Have you double checked that the action is correct for the the blocked senders ? (see screenshot)
However, while testing (with mote to junk) I've noticed that if you have mail forwarding configured on your account, it still forwards it. I guess it should avoid the forwarding here, or maybe I'm wrong.
Or maybe better, to have a setting like "Forwarding for blocked sender" On/Off ?
