Recently our spam load has gone up dramatically. I'm not sure why the spam filters are letting so much spam in. Sometimes DSPAM tags it but it get's allowed anyway. Yesterday I fed satrain 5000 messages from my junk folder. It seems to work ok for the rest of the day - but this morning a bunch got through again. Also, there was an error message about connecting to the MySQL database, so I'm not sure what effect if any that woudl have had.

I'm frustrated because I don't know where to start looking for the problem. Can someone explain the chain of events for the spam filter so that I can start troubleshooting effectively? Also, if you need any log info let me know.
