1.  I think the domain displayed to the end user matters.  In my sample size 
of 1, it matters to me.  I know I'm not the average user, but independent of 
the question of how many users it matters to, there are some.

2.  When abusers use different domains to send mail, it adds more information 
for filters to work on, so even if this is all about filtering, that works 
better too.
