Spam Issues

I have serious spam issues. I have users complain all the time about spam, and nothing seems to help. And to top it off, spam filtering uses tons of ram and cpu. It is filtering about 1500 spam messages per day out of the inbox's of the users who are complaining, but still letting through about 300-400 spam messages and pretty obvious ones. I was considering switching to the spamd/c mode to save ram & cpu, since no one really uses the usermin to train spam except me, but there are a few users who do not want spam filtering on their accounts at all. Is there a way to turn spam filtering off per account while using the spamd/c method? How do I train the spam database if I am in spamd/c mode?
