I use it or I wouldn't have known how to use it. ;) Like most other DNS blacklists, I wouldn't trust it completely. Whether something is "spam" depends largely on the perception of the person reviewing it. I don't know how you get in one list or another for mxrate, but I do know that a number of messages get flagged somewhat incorrectly at least in my perception of it. So, if you use it, score it where it helps you increase or decrease the score, but realize it will likely flag some real e-mail as "recommend block". It did here. So I treat it as "more likely to be spam" rather than "block this e-mail". Bret
