After a hard drive crash I re-installed windows 7 and Windows Live Mail. Now the Junk Mail filters don't work. No matter how many times I flag a message as junk it still comes through to my inbox. Before the crash a dialog box would appear telling me there was junk mail, then when I clicked on the button all the junk mail was pulled from the inbox and into the junk folder. None of that happens anymore. What can I do to avoid having to go through 60 or 70 emails every day?
