Open Relay Report: Lotus Domino

An SMTP open relay is a mail server that permits an unknown, outside sender to pass mail through the server to unknown, outside recipients, usually without the consent of its manager. This gives professional spammers a ready delivery mechanism for dumping unsolicited commercial email (UCE) on undeserving end-users while avoiding detection. It's easy to see why spammers favor open relays. They can abuse other people's bandwidth and mail servers, without getting blocked, blacklisted, or suffering negative publicity.
