I'm going to read that very carefully - it looks like it's very similar to what I did before, although perhaps the error messages are different... not that it's important how I tell the spammers to get lost! ;{)

We had something like this on all our raqs and it was great - I moved our site (webyourbusiness.com) to a new raq without the config (and I couldn't find my note on how to do it), and my SPAM has increased about 100x !!!!   I'm putting it onto our 2 new RAQs which don't have it ASAP!

thanks for digging this up Dan!
