Essentially no. The problem is MailScanner disarms the web bug by
replacing it's URL with a safe one that doesn't include tracking info.

The issue is if MS puts a file:/// URL in the message as the src of the
image, the client reading the message is probably on the user's
workstation or phone or tablet and the file:/// URL won't work because
the image is on the server, not the client.
