 === Flush deferred email from one queue to another queue ===
 
-If deferred email is building up in one instance (referred to below as the clogged instance), you can move it to another instance (referred to below as the target instance). For example if msn-a is deferring email (clogged), but msn-b is delivering (target), you can move all deferred email from msn-a to msn-b by following these steps.
+If deferred email is building up in one instance (referred to below as the clogged instance), you can move it to another instance (referred to below as the target instance). For example if aol-b is deferring email (clogged), but aol-a is delivering (target), you can move all deferred email from msn-a to msn-b by following these steps.
  
+NOTE: This only works if you move the messages between instances on the same server.
+
  * Figure out which instance is running with which IP address:
 {{{
-0 rustin:~# grep bind /etc/postfix-msn-{a,b}/master.cf
-/etc/postfix-msn-a/master.cf:smtp      unix  -       -       -       -       -       smtp -o smtp_bind_address=209.51.172.9
-/etc/postfix-msn-b/master.cf:smtp      unix  -       -       -       -       -       smtp -o smtp_bind_address=216.66.15.4
-0 rustin:~#
+0 cleveland:~# ip addr | grep aol
+    inet 216.66.23.44/27 brd 216.66.23.63 scope global eth0:aola
+    inet 162.247.75.211/24 brd 162.247.75.255 scope global secondary eth0:aolb
+0 cleveland:~#
 }}}
- * Ensure that the target instance will accept relayed email from the clogged instance. Edit main.cf on the target instance (in this case /etc/postfix-msn-b/main.cf), adding the clogged instance's IP address (209.51.172.9) in the mynetworks line.
- * Create the file /etc/postfix-msn-a/transport.relay with the contents that instruct the instance to flush all email to the server running on the IP address 216.66.15.4.
+ * Pull all deferred messages on hold on the clogged instance:
 {{{
-* smtp:216.66.15.4
+0 cleveland:~# postsuper -c /etc/postfix-aol-b/ -h ALL deferred
+postsuper: Placed on hold: 127 messages
+0 cleveland:~#
 }}}
-Note: you can replace * with a domain name if you only wanted to flush messages going to hotmail.com but not outlook.com.
- * Run `postmap /etc/postfix-msn-a/transport.relay`
- * Edit /etc/postfix-msn-a/main.cf and uncomment the transport_maps line at the end of the file.
- * Reload postfix: /etc/init.d/postfix reload
- * Flush:
+ * Move all held messages to the target maildrop folder
 {{{
-postfix -c /etc/postfix-msn-a flush
+0 cleveland:~# mv /var/spool/postfix-aol-b/hold/* /var/spool/postfix-aol-a/maildrop/
+0 cleveland:~#
+}}}
+ * Clean up. Deferred messages have a corresponding file in the defer queue with the reason why they were deferred. Delete these files.
