Third-Party Mail Relay (Open Relay) and Microsoft Exchange Server
- Abstract
- In the following paper I will be discussing the topic of Third Party Mail Relay, or Open Relay, the SMTP protocol, and the unwanted side affects of having a system that is configured as an open relay. Next I will go over the procedure of configuring Microsoft's email server software, called Exchange, so that it is not an open relay.
