I'm afraid I don't have an answer to your particular question. In case nothing else comes up and you decide to reconsider the idea of running a spam filter, I've been using bgp-spamd[0] quite successfully on a machine with very few resources and have been getting virtually no spam. At the very least, even if you decide to continue forwarding everything to Gmail, it would eliminate much of the spam you're currently forwarding to Gmail and would hopefully get your non-spam to spam ratio to an acceptable level.
