Do you rewrite/forward mail? .. we're a .edu, and allow our students to 
forward to hotmail/yahoo/whatever .. so when a phishing/malware sweep 
hits campus, about 60% is reflected back onto the Internet (sometimes 
our Anticrap gateway catches it, sometimes not). Because of the way 
addresses are re-written, it looks like it came from us.

They're true to their word here .. we got ourselves de-listed in ~12hrs.
