Eudora Pro Security Hole for Windows Only -- After last week's CIAC advisory regarding possible security problems in primarily Windows email clients, a different security issue has been revealed in Windows versions of Eudora Pro. Eudora Pro 4.0, 4.01, and 4.1 betas for Windows can utilize Microsoft's HTML viewer when displaying messages, and that viewer can permit automatic execution of items included in the message, such as Java applets. In theory, other Windows applications that use Microsoft's HTML viewer could also be vulnerable. Qualcomm has released an updater to 4.0.2 that makes Eudora Pro ask for permission before executing programs automatically. 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 so users must specifically choose to execute them. However, the bottom line remains unchanged: don't launch any attachments unless you're sure they're safe. [GD]
View Full Threads in Apple Mail
Many users are aware of Apple Mail's message threading feature, which highlights related email messages within the Inbox. However, many people don't know how to view both sent and received messages within a thread at once. To do so, first enable Message Threading under Mail's Viewing Preferences. Then, Command-click both the mailbox containing your threaded messages, and your Sent box. Now you can view both sent and received messages within the thread simultaneously.
