For whatever it's worth, Stanford's main campus servers never bounce spam
for basically this reason. We either silently discard it if it's
extremely high-probability spam or we deliver it tagged and let the
recipient filter it or not as they choose.
Bouncing spam is a reliable way to mailbomb some innocent person, and as
someone who's been mailbombed by such things repeatedly, I don't like the
experience. This is true even when you do it properly at the SMTP level,
since there are numerous ways in which spam gets forwarded, particularly
in a university context where there are a lot of departmental mail servers
and a lot of forwarding back and forth to one's server of choice. None of
the attempted reworks of the SMTP protocol to address this have really
I can't speak for CS, however; I'm not sure what they do.
