Spammers have found a way around the filter. You can see how they do it by clicking "reply all." If you look at the original message, you will see 3 "from" lines. First one is blank, the 2nd line has YOUR" email address, and 3rd line is the spammer email address. Pretty much, they're fooling hotmail into thinking that you are sending yourself an email. They are fooling the rules and filters. Microsoft support keeps telling people the add the spammer email addresses to your blocked list, but that won't solve anything. THEY NEED TO FIX THE SPAMMING LOOPHOLE!!!
