I propose an optional feature for current mail systems. The main idea is if a message is considered spam, this spam status can be tracked by the sender (but not sent to him directly, as the From field can be faked). The message can be re-marked as "not spam" if the sender can solve a CAPTCHA. Sounds like a dream come true for 419 scammers... Whether a mail is considered spam is entirely on the recipient's discretion. Not the sender's. That said, Henrik is correct -- this is off-topic for SA. I don't agree it is off topic. I think any discussion of possible ways to block spam is on topic. Even if the idea turns out to be not workable generally you have to have 5 bad ideas for every good idea. And a bad idea might get someone thinking who comes up with a better idea. I personally am always looking for the next good idea so I want to encourage anyone who even thinks they might have the next solution to blocking spam., or passing ham.
