Just finished setting up the 2011SBS server, converted over from 2003 Standard and 2003 ExchangeSP2.
Internal and outbound mail work fine. outbound to inbound does not work.
I went through the troubleshooter and it did send an email to an internal user, but there was an error message. Mail submission failed: Error message: Server does not support secure connections.
Using the EMC under Organization Configuration/Hub Transport/Edge Subscriptions Tab there is nothing...should there be something there?
I looked at the receive connector (setup by default, I assume) and permissions does have Anonomous users ticked.
