I'm fairly well used to setting these things up in other environments.  

This is a Dell PowerEdge T110 II.  OMSA 7.4.0 is installed.
I see System \ Alert Management \ Alert Actions \ Alert Actions Information with icons showing on the right of that.  I select E-mail.  

- What's not clear in the email setup is which email server is being assumed?  

-What's also not clear is the relationship between this dialog and the settings for Broadcast Message.  One might well assume that they are connected.  Otherwise, how is an email to be sent when there's an alert?
