Feature Request: MailScannerWebBug

[Julian Field]

Okay, I've written this for you. There is a new configuration option  
"Allowed Web Bug Filenames" which is a space or comma-separated list  
of filenames or bits of filenames. If the filename in the web bug  
location (just the filename, not any directories or host names)  
matches the list of allowed web bug filenames, then it is ignored.

A suitable setting might be
Allowed Web Bug Filenames = spacer pixel.gif pixel.png
