I second that.We moved from dspam to spamassassin/greylisting, and I'm surprised if a spam makes it to my inbox, where before, I felt like I'd have to spend an hour every other day training and cleaning up. Greylisting was what made it amazing.

I have the delay set to 1 minute (I believe the default is 5 minutes). Do you find that a longer delay actually helps significantly more? From what I remember in the documentation, the theory is that in that delay time, the chances of the spamming source getting put on a blacklist increases. This way, when the message finally makes it through, its finally on a blacklist and spamassassin has a better chance of catching spam. Do you find this to be the case?You'd think so, but I have seen spammers who retry. It would be interesting to do an analysis of it but I've never quite been that motivated. I can say that after I added greylisting, my spam levels have dropped off quite a bit. It's worth the wait to me.
