In the past, third-party mail relays were useful for allowing network administrators to debug mail connectivity issues and route mail around known problems. Spammers, however, have learned that by hijacking these open relays, they can in effect "launder" their spam by successfully delivering their unsolicited e-mail while spoofing their own identity. Spammers are able to locate accessible third-party mail relay servers by using automated tools that are readily available on the Internet. By relaying mail through several open relay mail servers at the same time, it is possible to flood the Internet with large amounts of junk mail in a very short period of time before being detected. Spammers who use third-party mail relays not only damage the reputation of those whose servers they have hijacked, clog networks with junk mail, and frequently crash servers -- they are guilty of breaking the law because technically, they are stealing services.
