I do see one big problem, Can you say "up to 40% of an incoming day's mail before I did this?" I thought so. :-( > though: FreeBSD-questions.

By implementing these measures, you may not kill -questions, but I didn't say we were killing AOL.COM, I merely cited them as an example of someplace people generally didn't want to be. :) As I said, the highest ratio of rejection comes from blocking invalid mail hosts and if these newcomer types have clueless admins or haven't registered their boxes properly, well, "sorry, I guess" :-) > I've taken a quite look at http://tech.gulf.net/spam/, and note that > they have a list of blacklisted IP addresses as well. Wouldn't that > be an alternative to domain names? Sure, but I think the biggest issue here is unresolvable host names - changing this part of the equation won't have any effect on those folks.
