Do you have any information about how to configure it to not do<br /> this?<br /> <br /> <br /> ====Resolution====<br /> With versions of Exchange Server below 5.0 it is impossible to configure the<br /> server to be a secured relay. If your Exchange Server version is below version<br /> 5.0 the recommended path is to upgrade to at least Exchange server 5.5 Service<br /> Pack 2 with the encapsulated SMTP relay address patch.<br /> <br /> There are several links listed below. The first is a third-party service<br /> where you can go to their website, plugin the IP address of your mailserver,<br /> and it will run a test to see if your mail server is misconfigured.<br /> <br /> If your mail server accepts the test message that the automated test tries to<br /> relay through it, the test will report that your mail server is an open relay.<br /> This does indicate that your server is misconfigured, but it might not be true<br /> that your server is relaying.<br /> <br /> If a mail server is configured properly, when someone, including this test,<br /> tries to relay through it, the mail server should refuse to accept the message.<br /> A common misconfiguration is for the mail server to accept the mail, then bounce<br /> it. This is better than relaying, but it is still a problem that needs to be<br /> fixed. To a spammer, that server will look like an open relay, and they will<br /> deliver hundreds, thousands, perhaps millions of messages to it, that it will<br /> then have to bounce. This will obviously affect the performance of your<br /> mail server. A second issue with this misconfiguration is that you can<br /> be used in a denial of service attack against someone else.<br /> <br /> The links following the link for the open relay test are all articles on how<br /> to properly configure a MS Exchange server. They explain both how to prevent<br /> your Exchange server from being an open relay, and how to fix the &quot;accept/bounce&quot;<br /> misconfiguration.<br /> <br /> ====Related URLS====<br /> http://rr.sans.org/email/open_relay.php<br /> http://mail-abuse.org/tsi/ar-fix.html<br /> http://www.microsoft.com/technet/security/bulletin/fq99-027.asp<br /> http://www.exchangeadmin.com/Articles/Index.cfm?ArticleID=7696<br /> http://nocops.pacific.net.sg/serviceLink/mailrelaycheck.html</div>
