[Mimedefang] Why 'defanged_src' ?

[Matthew.van.Eerde at hbinc.com]

Many email blasts use a "tracking image" to keep track of which emails get
read

something like
< img height="1" width="1"
src="http://server/track.cgi?email=your@email.address&campaign=some_camp
aign_number" />

This could be construed as an invasion of privacy - hence defanging
