REVIEW:
Spam Arrest was selected as the premier example of a subscription type host-based product. It operates as a “challenge-response” system in which all incoming messages (except those from user-predefined whitelist addresses and previously verified senders) generate a “challenge” to the sender that must elicit a human response (first time only) to verify that the sender is not an automated system (e.g., a spamming program). For safety, unverified messages are kept for seven days to allow examination by the user.
Enabling this product immediately halts all incoming messages not previously whitelisted or verified.
