I have to agree that this could be one of the most powerful tools yet to fight SPAM. I would pay money for this even if it were a seperate product! A couple of questions about the implementation:
1- If the sender does not acknowledge the confirm request, do they go onto the blacklist? This could be helpful if its given a TTL and when expired goes onto the blacklist. This would help reduce traffic when a spammer sends repeated messages. 2- Will it be server and per user based? I don't want to configure anything on the client for this and I don't want to traffic to/from the client for confirm request/receipt. 3- Would it be specific to Imail? Would it be a gateway in front of the mail server? 4- How will the onslaught of "undeliverable" messages be handled? I would imagine that most of the SPAM messages would not have valid senders, and those would produce "undeliverable" messages. 5- If a message from a blacklisted address arrives, can it be put into a hold bin instead of deleted? Maybe the Imail SPAM folder, so we can continue to SpamReview on them. Thanks and I want to push for this product!!

The sender confirms by replying to this request message and then the original message will be delivered. This has the benefit of: Automated for the user. they just start out with an "empty" individual white-list. Catches most spam - since the "confirm" message will bounce if it is sent to a fake sender and that accounts for a lot of the spam Can be customized - user can reset or manually change their "whitelist" if they want to. works for the naiive user - simple system config can enable or disable the feature per-user but the actual user need do nothing (doesn't have to learn anything) The spam that does slip thru would still be processed by all the usual weighted scoring algorithms. --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
