This is by design. At this time, we are not inclined to allow users to modify the action of the block action. Flexibility within the product is almost always welcome; however, it's not always necessary and can often result in bloatware of settings or functionality. In SmarterMail 16.x, blocking a sender will send all future messages to Junk Email folder, which follows suit with the mark as spam features found in common email services.
That said, we are discussing the best method for users to manage spam and unwanted emails in their mailbox. There are many threads relating to the Block Sender and Mark Spam functionality throughout this Community, so we are locking those threads in favor of creating one thread to centralize the discussion and ensure we are meeting your needs.
