+	  <para>The FreeBSD.org mail system rejects mail that is
+            either misconfigured or is potential spam.  Your mail
+            might bounce for one of the following reasons:</para>

+
+              <para>The FreeBSD mail servers reject email from known
+                spam sources.  If you have service through a company
+                or domain who generates or relays spam, please switch
+                to a service provider who does not.</para>

+              <para>The mailer at FreeBSD.org cannot resolve the IP
+                address of the connecting host back to a symbolic

+
+              <para>Working reverse DNS is a standard requirement for
+                accepting mail from a host. Set up reverse DNS for
+                your mail server's IP address.  Many home services
+                (DSL, cable, dialup, etc.) will not give you this
+                option.  In this case, relay your email through your
+                service provider's mail server.</para>
