Yes.  SpamAssassin uses a lot of memory.

If your server is performing well, don't worry about it.  (Seeing almost
no free memory is perfectly normal on a Linux system; Linux tries to use
all the memory it can for disk buffers.)

One thing you should try is turning on the embedded Perl interpreter.
This can help reduce memory per Perl slave.
