Ray, the correct protocol is "https://".
All you need do is enter your "www.p-s-s.com" detail into Publish > Other web host > Other web host settings > Website URL. As you are then Publishing to an http:// or https:// location, the Sitemap is ignorant of where it is and all should work.
Using "https://www.p-s-s.com" will probably work as well.
