Gmail has an excellent SPAM filter built right in. It's automatic.

Some stuff will get through from time to time, or the bad guys will figure out how to get around the filter, and you'll get a flood for a bit, but then google will figure it out and then it'll drop back down again. I've got an old Gmail account (not as old as KC though) and I get very little SPAM. I do occasionally get these emails these days with very little text that purport to be from someone warning me about something on some account or trying to sell me something, but they are always pretty obvious.
