A comment in a recent blog http://www.dotnetnuke.com/Default.aspx?tabid=825&EntryID=1433 stated that since 4.5 DNN has had sitemap functionality.  I though that I has someone elses sitemap installed. When I looked at the aspx it appears to be DNN's.  I have the following errors:

On portal 0 www.agingsafely.com/sitemap.aspx The URL line shows
<loc>http://www.agingsafely.comhttp://www.AgingSafely.com/AgingSafely/tabid/92/Default.aspx</loc> 
The portal has several portal aliases.  The ones below have only one

On basic.agingsafely.com it works

On newcastlehomes.agingsafely.com/sitemap.aspx it shows
<loc>http://newcastlehomes.agingsafely.comhttp://newcastlehomes.AgingSafely.com/Home/tabid/332/Default.aspx</loc>

On test1.agingsafely.com/sitemap.aspx it works

Can anyone who knows about this functionality please give me a clue how to fix it.  One of DNN pre-4.5 promles was that multiple portals and a common sitemap didn't play well with Google and friends.

No duplicates  I do have www.agingsafely.com and agingsafely.com but no duplicates and for 4 portals I have a total of 8 alias. However I hope to add a bunch in the next three months and would like to see this working.
