[Evolution] Blocking only images in HTML mail? (help w/answering a 3rd party query please)

[Adam Warner <lists consulting net nz>]

Hi all,

I was doing some Evolution advocacy and I'm stuck in answering this
question. Can someone please help answer it and I'll pass it on. The
relevant part of the discussion is below (thanks):

It does not have to be an _image_ fetched off the net that gives you
away.  Any data that HTML will fetch off the net, including an image,
a sound clip, a stylesheet, or another HTML page, can reveal that 
the e-mail has been read.

Does it only block _images_ (as the description would seem to indicate), 
or does it block _all_ loading of _any_ data off the web?

I use Agent which does not render HTML at all.
No loss, 99.9% of the HTML mail that I get is spam.
