Chuck,

First, I would not have changed Max Normal Queue Size to such a low 
value.  Basically you tell MS to never deliver emails in FIFO order, but 
to use a random order instead.  Max Children is also a tad on the high 
side...

That being said, I think you may have a DNS problem.  Do you have a 
local caching-nameserver?  If not, you should.  RBL relies heavily on DNS!
