 We are running two servers (rustin in Telehouse and cleveland in XO) that are configured to run multiple instances of postfix.
 
-These servers relay mail on behalf of our servers than send bulk mail:

+== The relays ==
+
+Currently, there is only one relay setup on rustin. The setup is handled in puppet by the following lines in rustin's pp file:
+
+{{{
+ class { "m_postfix::multi":
+    smtp_bind_ip => "216.66.22.61",
+    multi_instance_directories => [ "postfix-a" ]
+  }
+  m_postfix::multi_relay_instance { "postfix-a":
+   smtp_bind_ip => "216.66.23.37",
+   mynetworks => $::mfpl_relaying_ips
+  }
+}}}
+
+The first stanza should be included once for each host.
+
+The second stanza should be repeated for each relay instance on that host.
+
+When adding a new instance:
+
+ * Create a DNS Host record that associates the IP address to the host
+   (e.g. rustin.mayfirst.org <=> 216.66.23.37).
+ * Create an A record set to a.rustin.mayfirst.org (or b or c, etc corresponding
+   to how you have named the instance).
+
+== Using the relay ==
+
+To use a relay, add an entry to /etc/postfix/transport.relay, e.g.:
+
+{{{
+hotmail.com     smtp:a.rustin.mayfirst.org
+}}}
+
+The line above says: relay all mail destined for hotmail.com through a.rustin.mayfirst.org.
+
+At the moment this must be done by hand on each individual server. Once fully tested, it will be handled by puppet.
