What do you do to take it out of equation ?
What do you mean it never flows to the other server ?
Try like this:
>From another server do it about 5 times and post the results!
$ telnet 192.168.1.200 25
After it, go into the first server and shut down mail server and see if
ldirector set it weigh to 0 if it does, it should only goes to next server.
So for tests porpuses:
Shut down one mail sever and repet the test above.
WITHOUT restarting it, shutdown the other mail server, and repeat thet test
Now you can turn one the firt server again and repeat the teste.
When you post here the results i might be able to help!
