i'm far from an expert but at some level i believe that you're both

this piece of unwanted email?"
if it's a Real MTA, then kicking back a 550 will -- probably -- have the
MTA trying to return the message to the "sender". there will probably
be backscatter.
if it's NOT a real MTA -- if it's a spam proxy or a virus trying to send
the message -- then kicking back a 550 will -- probably -- have the message
dropped on the floor. there will probably not be backscatter.
so i think you're both right, more or less.
