Open Replacement For MAPS?
quackPOT asks: "Is there anyone with an open database similar to the MAPS DUL list? Now that MAPS charges for service, I either have to pay (which ain't gonna happen) or deal with the spam from direct client connections from crappy dial-ups. One of MAPS excuses for charging was the overhead cost of network bandwidth/etc/whatever. Why not distribute mirrors to other networks to reduce the amount of strain on their servers?"
here are some websites for replacements of ORBS and or MAPS

I keep one year's worth of mail logs for my company's mail server. The company is small, with about 1000 email accounts. With a simple grep I found that the RBL blocked 3000 messages in one year. That's about one message every 100 days per user. Obviously, the RBL is virtually worthless for our company, so we didn't pay for a subscription.
If possible you should see how many messages the MAPS services you used blocked for you. Notice that as far as I can tell MAPS doesn't provide any hard data for the success rate of their services. When they were free that wasn't so important but once money enters the equation I need some real eveidence.
Don't forget that MAPS is free for individuals' mail servers. It only costs if your server is for a business. This sounds wholly reasonable for me.
