Hosting - Domain Mapping

I have set up a site and am testing out a multisite instance. I note above you mention that SSL & Domain Mapping are a way off as yet - these would be crucial for me. I have installed Domain Mapping and set up two sites (and tried to map the domains over) with differing results - both failing to map to the sites.

I do however notice that I can add the new domain to my server and have the direction and SSL validity confirmed.

Any idea whats happening here ?
