I'm trying to set up WSUS to send email reports.
To make that happen, I created a new receive connector on our Exchange server. I've limited that server to the IP address of the server that hosts our WSUS role. I've then enabled anonymous access to the connector.
Yet, when I test the settings, I get an error similar to:
System.Net.Mail.SmtpException: 5.7.1 Client does not have permissions to send as this sender
