Exchange 2010 Edge Transport Server

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.

Thanks,

I completed that process, noted a full syncronization success. Added the DNS entries, local host entries as well, created an xml send connector info file, and imported it. All seems good.

Howeer, the SMTP Replay In Active Directory Site to Edge Transport Server (on the hub transport server) is in a continual retry status with messages in the queue.

Any idea how to troubleshoot the retry error on the hub transport server?

You mean outbound emails are stuck in the queues of your hub?

On your edge server ypu should have 2 connectors, edit the internal one and changethe authentication to allow exchange authenication

yes that's exactly the error I am talkign about

On the edge server -> EMC -> Receive Connector -> Internal Mail Servers -> Authentication -> TLS and Exchange Authentication should be chekced
