In the post above, Eric 4 is on the right track with slide number 10 in his link. It's just not under the anti virus tab. Do the following:
1. Click on Security Tab on Top.
2. Click on Anti-Spam Tab on Left.
3. Click on "Settings" in Anti-Spam window that pops up, next to the "STOP" Button.
4. A menu will pop up (like the one in Slide 10) of Eric's link.
5. Select the options you desire, the phishing option is #2.
6. If your using Outlook be careful, you might want to de-select the option in the MS Outlook section at the bottom that automatically moves marked item's to spam folder until you are satisfied with what is being moved.
That's it, hope it helps
