ASK - Active Spam Killer |
http://www.paganini.net/ask/ |
13433x |
This program (Active Spam Killer, or ASK for short) takes an "Active" approach in solving the problem: Everytime an email is received, a message is sent back to the sender asking for confirmation. If that sender does not confirm the message, it remains queued for delivery. If the sender confirms, the message is delivered and removed from the queue. The "confirmed" senders will be added to your "whitelist" and will never be sent another confirmation. Messages from these emails will always be delivered immediately . You can also specify an "ignorelist" for emails that should be always ignored and a "blacklist" that will cause a nastygram to be sent back to the sender everytime an email is received.

The SpamBouncer sorts suspected spam into three categories -- email sent by a virus, email from known spam sources which is definitely spam, and email which is probably spam, but might also be legitimate. It then tags each email with appropriate headers for the spam classification, and responds according to the parameters you have set.
