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.
