Spammers continually scan the Internet for open proxy relays: by using these open relays, they can obscure their originating IP address and remain anonymous. However, when a spammer comes across a service on a honeypot, that honeypot can collect valuable information about the spammer's true identity and help unmask it. In response to the threat that honeypots pose to spammers, the first commercial anti-honeypot technology has surfaced: Send-Safe's Honeypot Hunter (www.send-safe.com) attempts to detect "safe" proxies for use with bulk-mailing tools.
