All DSL/dialup accounts get a 554 from us (using a couple of RBLs), so I've actually seen our spam decrease lately.
I've used RBLs too, in the past. However, i've noticed legitimate mailservers sometimes turn up in such lists so we were "missing" mails, and there were quite a lot of complaints. I tried to put in less restrictive RBLs, but in the end I had to remove them.
Now I'm thinking to "enhance" my greylisting to check RBLs, and if the IP is found in an RBL, to increase the greylisting time...
