Arguably, *all* remote images are tracking pixels, regardless of how 
many pixels they contain.  Even without individualising the image URLs, 
you can more or less strongly correlate image loads to email recipients 
based on other qualifiers (User-Agent, time of day,...).

That said, I wouldn't object if MailMate could make an educated guess 
about images being "tracking pixels" in the stricter sense.
