On the heels of last week's CIAC advisory regarding possible MIME security problems in major Windows email clients, a different security issue has been revealed in Windows versions of Eudora, Qualcomm's widely used email program. Eudora Pro 4.0, 4.01, and 4.1 betas for Windows can utilize Microsoft's HTML viewer when displaying messages; that viewer can permit automatic execution of items included in the message, such as Java applets. In theory, other Windows applications which use Microsoft's HTML viewer could also be vulnerable to these sorts of problems. According to Qualcomm, updates to Eudora products to prevent this automatic execution will be available today. As a workaround, disable Microsoft's HTML viewer in the Viewing Mail settings panel of Eudora's Options dialog box. Eudora Light is not vulnerable, and Macintosh versions of Eudora have been safe for years because they encapsulate any attached applications such that users must specifically choose to execute them. However, the bottom line remains unchanged: don't run any email attachments unless you're sure they're safe.
Create Rules Based on Entourage Messages
When creating rules in Entourage 2008, you can save some time by selecting a message like those you want the rule to work on before defining the rule. That way, when you add criteria to your rule, Entourage fills in the data based on the data in the selected message. So if you wanted to filter messages containing TidBITS, you could select an issue and add a new "From Contains" criterion to a rule. Entourage will automatically fill in the email@example.com address in the criterion.
