The junk email filter in Outlook 2003 SP2 and Outlook 2007 includes an anti-phishing feature that will automatically disable hyperlinks in an e-mail message that may point to phishing websites.

Perfect but the phishing detection algorithm of Outlook can get funny sometimes - see the screenshot.

The email is actually a Microsoft Technet Newsletter from microsoft.com itself that was wrongly flagged by Outlook as a "potentially unsafe phishing message."
