Yes Joachim this is EXACTLY what I was looking for!..Thank you so much! 
My Inbox seems to be growing every day with more and more spam. I 
literally spent a whole hour and a half ...JUST adding email addresses 
to the "Block" list...and now that you've given me this knowledge, I 
should just be able to let in what I need and everything else will get 
tossed into the trash!..thanks so much! Happy New Year!!
