I get an error for the sitemap in webmaster tools for

Hi,

I get an error for the sitemap in webmaster tools for the url in the sitemap.
I am using multisite with domain mapping, and have then installed the smart crawl...

The thing is that accessing each site and look at the sitemap and download it through the smartcrawl shows the url to be correct, but Google Webmaster tools, show the multisite url, not the mapped domain url...

How is this effecting the sites SEO, and can it be fixed?
