A spam trap is
|“||a mail server that only has one purpose: to receive spam. It resides on a domain with e-mail addresses that is not used for any legitimate e-mail communication. The e-mail addresses from this domain are then posted on websites and other places from which spammers typically harvest e-mail addresses, when compiling their distribution lists. When the spammers eventually send out spam to these addresses, the spam trap logs the spam message, the time it is received, the IP addresses of the spam sending machine, and other details of the connection.||”|
