No, sorry Challenge/Response is just bad. Period. I can still remember the lengthy heated discussions back in the day with Len and Sandy and Scott and others.

I wanted to chime in here. We (MBF) actually have a utility for implementing exactly what Scott is proposing if anyone is interested in trying it. We call it The Gauntlet. Also, the following link has some additional information about how a program such as this works: http://www.lifeatwarp9.com/2012/06/gauntlet-a-solution-to-pre-tested-spam/. Please let me know if you have any questions about it.

It does have a big drawback, but the users may be OK with it if it stops the SPAM. Here is my idea. I am going to say this is from my standpoint of using SmarterMail. The basic idea is to process each message through declude twice. Any message that declude did not whitelist or delete would be sent to a hold queue folder and after a set amount of time declude would rescan the message. The first time through declude the message would process and drop out of declude only if whitelisted, or deleted. The message would also be counted by reputation tests such as barracuda. Once the message is processed it would be put in a hold queue where it would set for a set amount of time (Say 30 min). The delay would give a chance for tests to identify SPAM campaigns. After the Queue delay has passed Declude will process the message again and take the normal action to the message when complete.
