I happened to relay check our entire campus once back when I first started
my previous job.  I found an entire lab of around a dozen SGI's that were
of course open relays (among other things), a Sparc 20 that was an open
relay (which the FBI later confiscated), and an AIX machine that was an
open relay.  I knew where the first two groups were but didn't know where
the second was.  After searching our switches SAT's for that MAC I was
surprised to see that it was in the office next to mine.  The office of my
super, the lead sysadm.  Whoops!  OT story but I still find it funny. :)
