That's the key point--while Postfix listeners are relatively
small, they
each consume some resources (if only for their own local
variable and
data stacks), and at some hardware-dependent point you'll
eventually
start to notice that impact.  You may be able to run 200
listeners on
your "beefy" hardware, but that's not advisable
for a guy running
everything on a single PII-300 in his basement

A sad comment on the state of spam, certainly.  But you're
doing the
right thing by doing as much blocking upstream from Maia as
you can
reasonably afford to do without incurring false positives. 
Getting rid
of the most "obvious" stuff before Maia ever gets
a look at it is just
good resource management.

This also makes a good case for running additional Postfix
listeners,
though, since the listeners that are handling all of these
rejections
can't otherwise be feeding mail to amavisd-maia listeners
behind them.
200 still sounds very high to me, but since you have the
hardware...
