NewsForge is running a story on OpenDNS, a new re-thought and compatible implementation of dns that can fix spelling errors, typos and even help in blocking phishing sites.
These guys did a great job of taking something that has always existed and is deeply rooted at the heart of the Internet and improved it while keeping it compatible. It is so simple that you wonder how you didn't come to think of it earlier, like the egg of Columbus!
Before you rush to try it out think about the implications of its spelling correction on your mail servers while they attempt to deliver mail. This could save you a couple of bounce back if you're lucky, but it could screw your DNSBLs.
It seems that OpenDNS is smart enough to figure out if you're querying a BL, so it should be safe even on mail servers.
