I am setting up an exchange 2010 edge transport service on a workgroup computer, outside of the local domain.
Setting up inbound email doesn't seem to be an issue. I am having trouble with the outbound emails relaying. I set up the send connector from the transport service on the exchange servers, but it says unable to relay. I set up the connectors with the right port, and authentication on the edge transport service, but no go. Any ideas on how to troubleshoot?
I have always used a hardware solutoin (cisco spam routers) which takes minutes to set up to get working but wanted to give 2010 a try for being the outbound mail service.
