This will be a spamasassin problem, we suffered the same fate, disable SA 
and it will skim through your queue in a couple minutes.

You will need to fine tune SA, if you have 2 CPUs in that box, make 
of mailscanner processes 10, batches of 50, and SA scan msg of no more 
than 30k.

To get through them now just disable spam assassin and sighup mailscanner, 
else things will only get worse.
