Recently, Rob wrote about a tool, Proxifier, that can intercept requests from specific processes. Proxifier is available for Windows, macOS, and Android.

Besides serving as a place where Microsoft Outlook places suspected spam, the Outlook Junk folder has one additional function that can be quite helpful when it comes to identifying malicious messages.
