That server should handle much higher volumes of mail.  Try invoking
mimedefang-multiplexor with the "-Z" option; then use the command:

		       md-mx-ctrl busyslaves

to see what the scanners are doing.  If you're using SpamAssassin, it
can be a real CPU pig, but 1 message/second should be no problem even for it.
