I wish to use Domain Blocking directly from the SPAM folder that auto strips out the domain name from one or more mail addresses. Choose the option, click the button, and--viola--no more spam from those bad boys. Problem is the criminals just auto generate a gazillion more phony addresses and the blocking process continues evermore. Got to beat them back some day soon with better email technology--but not sure why it's taking so long.
