junk email filtering is not working properly

I have a user who has the email junk filter option set to do "no automatic filtering" yet this is not stopping a ton of email from going to the junk email folder. I have my setting set to the same thing with no problem. She only has two senders in her blocked senders list. We are using Outlook 2010 and Windows 7. I am wondering what the fix here might be?

Thanks!
