For what it's worth, I still test against REVDNS and it's never been worth a HOLD action all by itself. I score it at 25% of my HOLD weight threshold. Reverse DNS lookups can go through a lot of lookups; if their DNS is too slow and doesn't respond, you will inadvertently score against them unfairly. Worse, if your DNS is slow or your Internet tube is clogged, you'll inadvertently score against everybody. I keep a single file full of counterweight lines (instead of whitelisting) and the comments are inconsistent, but a quick check tells me that 4% of the comments I made included a mention that the sender triggered REVDNS. If you want to get fancy, look into using or making "combo" tests where you add weight based on tests being triggered. Andrew from Vancouver.
