Test remote system for unsecured mail relay

The rlytest utility tests a host to determine whether it will relay third-party email. It will try to relay an email message to yourself through that host. A host that allows third-party relay is subject to attack by Internet vandals, and frequently is hijacked by spammers to relay massive amounts of junk email. A host that allows third-party relay should IMMEDIATELY be secured, disconnected, or shunned as a menace to the Internet.
