Exchange 2010 - Error submitting email

Hi,

I just installed Exchange 2010 and upgraded to SP3 in my home lab to work with Sharepoint 2010. I ran the Microsoft Exchange Troubleshooting Assistant and received two errors. Any help is much appreciated. Regards.

1. Mail submission failed. SMTP host was not specified.

2. Mail submission failed. The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.1 Client was not authenticated.

1. Check the properties of the SMTP connector and ensure all Exchange services are running by running the below command
Test-ServiceHealth

2. Is this a single server environment ? Have you installed all 3 default roles on it ?
