I finally got oVirt node installed with gluster on a single node.

Once that step was complete...
I noticed that the Engine Deployment wizard asks for SMTP settings for where to send notifications. I was kind of surprised that it doesn't allow one to enter any credentials. It looks like this requires an unauthenticated local relay. I don't like that. :) See attached screenshot.

Has there been any talk about adding this into the wizard deployment?
