Suprisingly not the case. In the last 4 or 5 years mail server admins - 
even the dumb ones - aren't being as obviously stupid as they used to be. 
(Open Mail Relay is no longer the big bane.)

Insecure boxen (mostly windows) are the cause of most of the worlds grief 
now.  And the increasing number of broadband connections available to 
end-users are only making the situ worse.

(NAT helps slightly, which keeps NZ's stats relatively low, but places 
with Cable and other PPPoE type links where the link terminates on the 
end-user's wide-open system, are the big guilty parties.)

My experience (which is now a coupla years old, mind you) is that most 
NZ-originated spam comes from spyware ridden windows machines. Even NAT 
wont stop you from becoming a relay when you actually click-on and run the 
vulnerability....
