I have found that Greylisting works spectacularly well for my needs. I have SA as the 2nd line of defense, but it rarely gets called upon to declare an email as spam. Greylisting works because of two things: 1) The SMTP protocol requires SMTP servers to re-try delivery to a remote server if they are given a soft error code; and 2) Most spam bots will give up if they receive any error code, and move on to another address.
