Setting hostname for tcp transport table fails #31

Hello,

short: change the service=TcpTable MBean under the subetha Options. (stop,
change, apply, start) - still returns the localhost IP
trying to get the tcp transport to work with postfix.

My setup is the following:

DNS is set up for internal and external network separately but yields the right
values.

mx.example.com :: Postfix
  2 NICs (1 Public, 1 Private)
  Private IP 10.0.0.1
subetha.example.com :: jboss with subetha
  1 NIC
  Private IP 10.0.0.2 (hostname is subetha.example.com)
  reachable by postfix
  all mail to lists.example.com is routed there

Now looking up the protocol in http://www.postfix.org/tcp_table.5.html I made up
the following session.

# nc subetha.example.com 2502
get everyone@lists.example.com
200 smtp:[127.0.0.1]:2500

# postmap -q "everyone@lists.example.com" tcp:subetha.example.com:2502
smtp:[127.0.0.1]:2500

as you can see the problem is that subetha returns 127.0.0.1 as the transport
endpoint which of course won't work.

 * Now go to you jboss at Port 8080
 * Open the jmx Management Console
 * Search for the Subetha Options
 * go to the the "service=TcpTable" link
 * invoke "stop()"
 * HostName set to subetha.example.com
 * Apply Changes
 * Refresh MBean View reloads the page with the correct hostname
 * invoke "start()" (No errors until here)

Now again (first postmap then nc):

# postmap -q "everyone@lists.example.com" tcp:subetha.example.com:2502
postmap: warning: read TCP map reply from subetha.example.com:2502: unexpected

smtp:[127.0.0.1]:2500
#

# nc subetha.openforce.com 2502
get everyone@lists.openforce.com
#

Problems:

1. Subetha still returns the localhost IP
2. as postmap indicates there seems to be some problem restarting the MBean
correctly (forgive me the lack of terms, new to JBoss and SubEtha)
