I'm having a little bit of trouble setting this up.
I need to setup this server to be a outbound relay to mimecast.

I have the server's IP mapped to a IP translated to an allowed IP for mimecast. and I configured that in the Relay Hosts.

But I cant figure out what I'm missing. I'm trying to do test emails to see if it will send the email out to mimecast and then back to me. But it looks like its just trying to send it to its self. Do I have to empty out the allowed domains?
