Astaro security Linux has a webproxy that has an option(which i use) to block web bugs....:)
How can it tell web bugs from any other HTTP requests? The only thing that makes a URL contain a web bug is that I only sent it to you. So if I control images.example.com, and I send you and only you an email that includes the image http://images.example.com/faces/smile.png but on the server smile.png is a script that records information from your HTTP request before generating an image of a smile, how does your proxy distinguish my web bug from a normal image? They only look like obvious web bugs if I need to track thousands of recipients. If I've targeted you, you just can't tell.
