Tim,

My servers don't accept mail from outside our University (blocked by 
iptables).  Emails could have entered from some other server on the 
campus and relayed to my servers, though... but would not have made it 
back to the outside world unless perfectly clean!

Fortunately, they blacklist for *only* 24 hours when something hits 
their smap traps...
