[ILUG] sanitize/disable image loading

[( Admin ) bryan]

It occurs to me that a large amount of Spam gets it's feedback when 
someone loads an
email and it contains an external image link.

Is there any popular way to disable this is ? For example here is what 
Thunderbird
does when you mark a message as Spam ....
snip=
<A href=3D"http://fork.pasede.com/gp/default.asp?ID=3D10045"><IMG 
alt=3D"Here" hspace=3D0 src=3D"http://lugging.haoltal.com/hi.gif" 
align=3Dbaseline border=3D0></A>
=snip

I can't see any immediate reference to this in the 
spamassassin/sanitizer documentation .

I don't think banning html messages altogether would please my users.
