You version of MS is so old that it probably does not have this feature:
# If more messages are found in the queue than this, then switch to an
# "accelerated" mode of processing messages. This will cause it to stop
# scanning messages in strict date order, but in the order it finds them
# in the queue. If your queue is bigger than this size a lot of the time,
# then some messages could be greatly delayed. So treat this option as
# "in emergency only".
Max Normal Queue Size = 800

This would really help your server process those emails faster.
