Am reliving my WSUS 3 days on a new box finally 
Problem is, I can't get the email reports to work. We are running Exchange 2007 and I want it to send the report to an external address:
Here is the error:
I've tried setting the admin with "Send as" properties in AD and have set a new receive connector in Exchange with anonymous users ticked but still the same error.
Anyone?
