[snipped intersting stuff]

what i do not like is HTML mail with external links... this way the 1 pixel 
(or larger) image can be used to identify you by email address. (and get 
your mail on the "verified" lists)

a filtering proxy does help agains some of the collectors but there are 
just too many out there.

any real solutions availble?
