I assume you already have /var/spool/MIMEDefang mounted as a tmpfs volume?
SpamAssassin is the real hog, usually. If you can avoid calling it, do
so. Do cheap rejection tests first -- for example, if you drop Windoze
executables, do those tests first and then don't bother calling SpamAssassin.
Try enabling the embedded Perl interpreter; that might reduce memory
consumption per slave and let you run more slaves.
Allow request queuing in the multiplexor. Avoid network-related tests
inside your MIMEDefang filter.
The hardware you mentioned seems pretty fast to me. You should easily
be able to handle 2 million messages/day on four boxes like the ones
you have. With 4GB of RAM, I would bump MX_MAXIMUM up to 100, and set
MX_MINIMUM to around 40.

David.
