We have configure our MX Logic Console and our MX records for spam filtering through MX Logic.  All emails are being rejected by the server with the message:host 208.65.144.245: no unauthenticated relaying permitted.

I added a new receive connector with the above IP address in the Receive mail from box on the network tab.  The "Use Local IP address" is set to (all available).

Authentication is set to Transport Layer Security (TLS); Basic authentication; integrated windows authentication

Permission group is set to: Anonymous users

I also have the default receive connector set as follows
Local IP address:  (all available) Port 25
Receive mail from remote servers (0.0.0.0-255.255.255.255)
Authentication: TLS; Basic authentication, other basic authentication only after starting tls; integrated windows authentication.
Permission groups: anonymous users; exchange users; exchange servers; legacy exchange servers.

Any help would be most appreciated.

The default one will allow anyone to connect to your server. Therefore if you are following best practises then you should change that connector configuration.

HOWEVER, the true best practise is to limit the traffic to port 25 at your firewall, not on the Exchange server. I would only change the connector if the firewall isn't up to doing that.

Don't forget to restart the Transport service after making any changes.

Although looking at your message again, I am pretty sure that isn't an Exchange error. Turn on logging and see whether you are actually seeing connections from MXLOGIC.

Simon.
