That would be called a "Joe Job", see <http://en.wikipedia.org/wiki/Joe_job>.

If they were originally sent out with the appropriate 
listname-bounces address, and the joe-job bounces were coming back to 
the list and it was trying to process them, then yes -- this would 
certainly explain a very heavy load on the system.

Otherwise, I'm not sure I have enough information to be able to make 
any more comments on this particular problem.
