The RBL provider is simply providing a list of IP's/Domain's that they have considered (by whatever methods - and I DONT agree with all of them) but the blocking is being done by the mail servers administrator(s). Spam is a problem, its not going to go away with the current methods of use, so filtering by whatever means is the only viable option - the challenge/response method definately has its merits, except when you have two different challenge/response systems in place, blocking any chance of either the sender or recipient from getting the challenge. I'm in an easy position where we don't have unknown clients attempting to reach us, contact is initiated outbound, or we know about any inbound email addresses (plus dealing with large corporates helps too :) Each to their own etc. ;) Anthony.
