I have setup gms 2.0.3 on a fresh SLES install. I think I am having difficulty with my SMTP Relay setup. I can't get any message to send. SMS does not work. I can access the web interface on the server and all appears to work. I get a message from Gwia 450 host is down when I try to do a relay. Any suggestions on how to correct this? I thought about setting up a SMTP server on the GMS server itself so a relay wouldn't be necessary.
