Trend Micro eMail ID is a web browser plug-in for Internet Explorer and Firefox in Beta that scans webmail and helps you identify legitimate email messages in your inbox. It uses a two-step check to verify the source and authenticity of email messages, and then displays the result in the “from” area. This prevents you from opening and acting on phishing messages attempting to spoof real companies.

Trend Micro eMail ID confirms the source of email messages using anti-spam technologies such as Sender ID and DomainKeys. After it gets a positive result from these authentication checks, eMail ID performs further checks for those messages against a list of identified senders. Once all tests have been cleared, TrendMicro eMail ID adds a Truemark icon against messages in your inbox to indicate legitimate messages.

In webmail clients, it also adds a button in the frame of the webmail to indicate it is active and scanning messages. If you move your mouse over a Truemark icon, a certificate appears, showing you the results of the authentication and identity checks, and giving you more detail about the sender of the message.

Trend Micro eMail ID is compatible with AOL/AIM, Yahoo, Windows Live-MSN, Google Gmail and Outlook Express on Windows XP and Vista. Click here to download Trend Micro eMail ID Beta.
