What you're missing is that the assumption that systems sending valid mail will always (or even will usually) be listed in DNS is fundamentally wrong and should never be used even as a weighted guess to indicate spam. In fact, what's listed in the MX record in DNS is systems where email should be sent. For any company larger than 50 employees, that's probably not the same as from where one could reasonably expect legitimate email. DNS provides no assertion about the sending of email, and any system that operates under the assumption that it does is inherently broken, because it'll get a false positive on better than half of the valid emails out there. It's a useless heuristic. -- gabriel rosenkoetter [EMAIL PROTECTED]
