===Honeypots===
{{Main|Honeypot (computing)}}

Another approach is simply creating an imitation MTA that gives the appearance of being an open mail relay, or an imitation TCP/IP proxy server that gives the appearance of being an open proxy. Spammers who probe systems for open relays and proxies will find such a host and attempt to send mail through it, wasting their time and resources, and potentially, revealing information about themselves and the origin of the spam they are sending to the entity that operates the honeypot. Such a system may simply discard the spam attempts, submit them to [[DNSBL]]s, or store them for analysis by the entity operating the honeypot that may enable identification of the spammer for blocking.
