Zombie EMAIL!

Do any of u guys have this problem with outlook?

I got this spam message a while ago about free web advertising. And I delelte it, and about an hour later it comes back. But the weird thing is that it says it was received a week ago. And It kept doing that, and pretty soon I have 15 or more of them that keep poping back from the dead and saying they were received a week ago. Now I have more messages by a different adress with the same title, and they are doing the same.

I’ve tried blocking them, blocking their domain, blockign their subject, deleting them, eveything! and they keep coming back! HELP!
