I will second the recommendation to increase your RAM to 1 GB.
SpamAssassin tends to use lots of RAM.  As long as you can keep it out
of swap, it runs great, but as soon as it runs out of memory and
starts swapping, your performance will drop like a rock and probably
cause mail to start piling up.

Your machine should be fast enough to run ClamAV and SpamAssassin
locally, as long as you increase the RAM.
