It’s now public that we added a phishing filter for Windows Mail in Windows Vista.
Phishing is a type of fraud designed to steal your identity. In phishing scams, scam artists try to get you to disclose valuable personal data—like credit card numbers, passwords, account data, or other information—by convincing you to provide it under false pretenses. Phishing e-mails claim to be from a trusted financial institution or online service. By including links to fraudulent websites, these e-mail messages can trick you into providing your personal information. Windows Mail has a phishing filter that analyzes e-mail to help detect these fraudulent links and help protect you from these online scams.
