[Evolution] Blocking a URL

[Internaut at Large <dkap haven org>]

A number of my emails seem to contain a URL from Yahoo, and sometimes it
takes a while to resolve it.  It seems to be just a marker or tag URL,
is there any way to block such?  They are of the format:

<!-- |**|begin egp html banner|**| -->

  <img
src="http://geo.yahoo.com/serv?s=97476590/grpId=14826722/grpspId=1705083802/msgId=12165/stime=1193882255"; 
width="1" height="1"> <br>

<!-- |**|end egp html banner|**| -->

And it would speed up my mail reading tremendously if this could be
blocked.  Anyone have any idea how it might be done?

Thanks!
