I use MS outlook for emails and the junk email filter had been working
on its own -- blocking junk emails and placing them in Junk E-mail
folder. Recently it has simply stopped working!

The only change I can think of that I made, was to add many more
addresses to the blocked sender's list.

I have the following setting, but I still receive emails from the
addresses in blocked sender's list, while the junk email folder
remains empty:
* Level of protection set to high
* Permanently delete junk emails instead of sending them to junk email
folder is UNchecked

Any suggestions on what might be happening and how I can fix this? All
suggestions are appreciated!
